16 Lateral Grating Laser Ridge Top View Sidewall Cross section Distributed Feedback (DFB) lasers can provide mode hop free tunability A grating etched laterally to the ridge acts as an internal optical filter that allows for single wavelength feedback. The grating linewidth is directly proportional to the wavelength of light, which for a 2µm laser is 295nm and 590nm for a 1 st order and a 2 nd order grating, respectively. The grating is defined by electron beam lithography and is etched in an ICP RIE etcher. The electronmicrographs show that there is no discontinuity in the grating, i.e. the grating completely covers the top, sidewalls, and edge of the laser ridge All rights reserved. 16
17 DFB Summary 3 & 4 µm Ridge Widths Fabricated both 1 st order and 2 nd order gratings Experimented with different grating pitches DFB coupling predicted to be small based on SEM AR coated to suppress facet reflectivity Maximum output power was factor of 6 lower for 2 nd order DFB (3.2 mw vs. 20 mw) All rights reserved. 17
