3 THz Lenses Polished Picarin Lenses focus THz and visible light Picarin is highly transparent in THz and visible spectral ranges (see transmission spectra on the next page). Refractive index of Picarin is almost the same for THz (n=1.56) and visible light (n=1.55). Unpolished Picarin Lenses Offer the best performance at 2-7 THz spectral range (see transmission spectra on the next page) Unpolished surfaces scatter visible and near-ir light Polyethylene Lenses The lenses are manufactured from a purified high-density polyethylene Offer the best performance at frequencies below 1 THz and above 7 THz (see transmission spectra on the next page Polyethylene is not transparent in visible and near-ir spectral ranges, so that the lenses can be used to block light.

8 THz Sources and Detectors Backward Wave Oscillators (BWOs): High power: mw Narrow spectral line-width: 1-10 MHz Wide spectral range: THz BWOs are electro-vacuum diodes, where THz emission is generated by electrons decelerating in a periodic electric field. BWO emission wavelength is tuned by a voltage applied to one of the electrodes (cathode). Tables below show tuning ranges for a number of different BWOs. BWO model # QS-260 ov84 QS-300 ov83 QS-350 ov82 QS-400 ov81 Frequency range, THz Output power, mw Cathode Voltage, kv Cathode current, ma BWO model # QS-500 ov80 QS-700 ov32 QS-1000 ov30 QS-1500 ov24 Frequency range, GHz Output power, mw Cathode Voltage, kv Cathode current, ma BWO model # QS-2.1 ov86 QS-3 ov71 QS-4 ov70 QS-6 ov69 Frequency range, GHz Output power, mw Cathode Voltage, kv Cathode Current, ma BWO cooling system: BWOs operating at frequencies above 180 GHz require water cooling. While BWO dissipates only 300 W of heat, the cooling system has to provide for at least 40 psi of water pressure, due to very narrow tubing on BWO. We recommend a Lytron chiller RC006G03, that can be also purchased from Microtech Instruments. 8
9 BWO Power Supplies and Magnets Operation of BWO-based THz sources requires a high voltage power supply (e.g. VR-6MU) and a magnetic system (e.g. MS-1.2) that houses a BWO tube. High Voltage Power Supplies: VR-series power supplies provide for highly stabilized cathode voltage ranging from 0 to 6000 V, as well as BWO grid and heater voltages. The software package ( EPSIL ) and digital-to-analog converter (DAC-16) enable user-friendly control of the system via RS- 232 or GPIB interfaces. Model # Max Voltage Application VR-2S 1500 V Low frequency BWOs (<180 GHz) VR-6M 6000 V High Frequency BWOs (>180 GHz) VR-6MU 6000 V All types of BWOs Focusing Magnetic System MS-1.2: MS-1.2 magnetic system includes a 1.2 Tesla permanent magnet designed to house high-frequency BWOs operating in the spectral range THz. The system is equipped with a 3-axis mechanical translation stage for centering BWO in the magnetic field. The system also has inputs for BWO electrical connections and water cooling system. 9

18 2 Microtech Instruments, Inc Transmission measurements is the best method for characterization of highly transparent materials. In particular, transmission spectra of plane parallel plates exhibit a periodic transmission pattern caused by interference (Fabry-Perot etalon fringes). Real and imaginary parts of the dielectric constant can be determined from these measurements, as the period and amplitude of the etalon fringes depend on the material refractive index and absorption, respectively. Characterization of semi-transparent materials requires a THz Mach-Zehnder interferometer (shown below), since no etalon fringes can be observed in the transmission spectra of such materials. The Mach-Zehnder setup enables measurements of a phase shift induced by the sample as a function of frequency. Combining this data with transmission spectrum, real and imaginary parts of the dielectric constant can be calculated.
