2 APPLICATIONS DETECTING BREAST CANCER CELLS USING GOLD NANOPARTICLES 1 [1] Sergiy Patskovsky, Eric Bergeron, David Rioux, and Michel Meunier, Hyperspectral darkfield microscopy of PEGylated gold nanoparticles targeting CD44-expressing cancer cells, Biophotonics, 213. Gold plasmonic nanoparticles (AuNPs) are used extensively as biomarkers, and are a viable candidate for a variety of other biological applications. However, it has been proven that their small size and the complex environment in which they navigate make their observation and characterization quite a challenge. In order to address this issue Patskovsky et al. 1 used a hyperspectral dark field microscope in backscattering configuration, replacing the usual white light illumination with by a tunable laser. With this set-up, the group of researchers was able to sweep the illumination over the range 4nm to 1nm. The wide range of wavelengths and high output power of the were essential parameters for this study. They could indeed follow the spatial position and distribution along the z axis of the AuNPs targeting CD44 (see figure 1), a cell surface receptor actively expressed in cancer stem cells. The hyperspectral imaging set-up described here can also be helpful in a wide range of biological applications requiring a combination of spatial and spectral information.

TESTING THE GEMINI PLANET IMAGER'S CORONAGRAPH The Gemini Planet Imager (GPI) is an astronomical instrument made to detect giant planets in nearby star system. The GPI uses a coronagraph in order to eliminate 99% of the coherent starlight. Before sending the GPI at Gemini South (located in Chilean Andes), it was crucial to test the coronagraph by reproducing the experimental conditions in which it would serve. The light required to measure its performances had to be nearly achromatic, tunable across the GPI's wavelength domain (near-ir.9-2.4µm), in addition to being powerful and collimated. Most of the light s match one or two of these requirements but only Photon etc's unequalled and efficient tunable laser combines all three above. The wide spectral range of the TLS and its high output power were exploited for sensitivity measurements of the imager. Figure 2 illustrates the sensitivity measurements of GPI s coronagraph across the astronomical H band ( µm). At the wavelengths it is most efficient (i.e. 1.6 and 1.6 µm), GPI s coronagraph allows the detection of a less than a million times fainter that the diffraction core of the unmasked star at a separation of only.3". This would be sufficient to detect a planet only slightly more massive than Jupiter around a 1 million year old Sun-like star.

SOLAR CELL EXTERNAL QUANTUM EFFICIENCY MAPPING 2 [2] L. Lombez, D. Ory, M. Paire, A. Delamarre, G. El. Hajje, J. F. Guillemoles, Micrometric investigation of external quantum efficiency in microcrystalline CuInGa(S,Se)2 solar cells, Thin Solid Films, 214. In the race for higher solar cell efficiency, a better understanding of their fundamental electronic properties is paramount. With that in mind, Lombez et al. 3 investigated the spatial variations in the spectral response of CuInGa(S,Se) 2 solar cells. In this study, Photon etc's TLS served as the illumination for measurements of light beam induced current (LBIC) at different excitation wavelengths. The LBIC experiment allowed an estimation of the external quantum efficiency (EQE) at different positions of the sample (see figure 3). The LBIC measurements at enough positions on the sample allowed a map reconstruction of EQE. To carry out successfully this experiment, the illumination needed both a wide spectral range and a high output power, delivered in a diffraction limited point to achieve the best spatial resolution. Combining all of the above requirements, Photon etc s TLS was chosen to excite the sample, mounted on a piezoelectric stage, to map the EQE for a large range of wavelengths..7 A) B).7 3 C).7 D) y-axis (µm) Wavelength (nm) x-axis (µm) Cell λ=84nm y-axis (µm) x-axis (µm) Cell λ=78nm y-axis (µm) x-axis (µm) Cell λ=1nm F3: measurement of the external quantum efficiency of 2µm diameter microcell.

3 79 DE GASPE AVENUE, #222 MONTREAL, QUEBEC, H2S 2X3 CANADA LLTF CONTRAST OPTIONS & ACCESSORIES LLTF DESCRIPTION The LLTF is a non-dispersive tunable bandpass filter that transmits a single laser line while blocking unwanted lines. It delivers the highest signal throughput in the industry. Output pointing is very stable, removing the need to realign optical setup. It is also ideal as a premonochromator for triple spectrograph. The LLTF is compatible with any VIS-NIR broadband, but is optimized to fit Fianium s s. Depending on the application, a series of options are available and described below.

4 OPTIONS Enhanced SWIR The Enhanced SWIR option allows to reach higher output power and to extend the spectral range of the LLTF up to 2 nm. As shown below, the standard version of the LLTF Constrast SWIR (in grey), combined with a 4W, already offers an interesting output power, but this can still be a limitation for certain demanding applications. The wide range of possible power output can of course solve this, but at a version high cost when compared to the Enhanced SWIR option. Also, the spectral window of the Enhanced SWIR option gives access to the complete spectrum of the used, a great advantage over the standard LLTF Contrast SWIR.,7,6, SWIR ENhANCEMENT OPTION WITH SWIR EXTENDED RANGE WITHOUT SWIR EXTENDED RANGE IMPROVEMENT (%) 7% 6% %,4 4%,3 3%,2 2%,1 1% % * Measured with WL-SC4-4 Fianium Supercontinuum Laser HIGH-RESOLUTION FWhM (nm) The high resolution option offers the possibility to reach a sub-nanometer bandwidth (FWHM). The spectral window covered will be reduced, but can still reach unmatched ranges for such narrow bandwidths. The figure shown here presents the typical evolution of the FWHM over the VIS ans SWIR range. We can customize the LLTF to cover up to of these ranges. Please contact us for more details

5 ACCESSORIES FIBERED OUTPUT The LLTF Contrast, in its basic configuration, delivers a collimated free-space output beam. The fibered output option takes this beam and couples it into a fiber to fit the needs of various applications. An X-Y-Z translation adjustment allows coupling optimization. The FC APC output is available with the following fibers: 1) 9/12 µm (single mode) 2) /12 µm (multimode) 3) 1/12 µm (multimode) HARMONIC FILTER HARMONIC FILTER - VIS HARMONIC FILTER - SWIR1 Our filtering technology is based on the use of resonant gratings. Thus, 2 nd harmonics of a given wavelength will not be blocked completely. The harmonic filter is a highpass filter that allows blocking this 2 nd harmonic. The harmonic filter for the LLTF Contrast VIS-2 blocks the harmonics coming from the region 4- nm. It will deploy automatically when it is enabled and the filter is set to concerned wavelengths (8-1 nm). The harmonic filter for the LLTF Contrast SWIR, when enabled, also allows blocking automatically the harmonics coming from the region 1-12 nm when the filter is set to wavelengths in the range 2-2 nm. Finally, the harmonic filter VIS-SWIR combines a permanent highpass filter to block harmonics coming from the region 4-1 nm and the automatic SWIR harmonic filter for the region 1-12 nm.

6 ACCESSORIES BACKGROUND SUPPRESSOR The purpose of the background suppressor is to remove unwanted reflections of light coming from the inside of the LLTF. This whitish halo is inherent to the core LLTF technology. The halo surrounds the filtered beam, but is not colinear. This phenomenon appears only when using the filter in its free-space configuration, and becomes more apparent as the power of the laser increases. Using any focusing system (e.g. Fiber Output option) naturally removes this unwanted halo. Beam Profile Through background suppressor Even if the halo appears only in small spectral regions and decreases rapidly in intensity over distance, it could be problematic for some applications. The spectral averaged intensity is indeed relatively low (few 1th of nw/nm at 3 cm from the LLTF output port), but will be completely removed by the background suppressor accessory if needed. It is to be noted that the laser beam quality (m 2 ) will not be significantly affected by this accessory. ALIGNMENT KIT (FOR FREE-SPACE) In free-space (input/output) configuration, the alignment of the input laser into the LLTF is a challenging task without the proper tools. The alignment kit allows the user to rapidly find the correct alignment. Two irises, mounted on removable posts, are easily placed at the entrance of the filter. The laser beam then simply needs to follow the path created by the irises. Photon etc. 79 de Gaspé Avenue, #222 Montreal, QUEBEC, H2S 2X3 CANADA T F E info@photonetc.com
