Non-Chromated Flexible Primer

Not Available Sensors Unlimited will grow, fabricate and test a broadened-wave guide distributed feedback laser designed to operate at a wavelength of 1.55 um. The goal of this program is the delivery of the relevant basic material and structural characterization necessary for the design of a broadened-wave guide DFB laser along with a reliable broadened-wave guide DFB laser emitting powers of at least 200 mW. The motivation for a 200 mW laser are the commercial and government RF-photonic applications such as links, modulated mm-wave communications sources, and local oscillator distribution for space radar. To achieve this goal, Sensor Unlimited will use the services of Sarnoff Corp to fabricate low-loss broadened wave guide structures. Such structures are expected to permit significant expansion of both modal cross sections and cavity length to dramatically reduce power density within the laser. In addition, we will separately fabricate structures for analysis of anti-guiding, current diffusion, carrier heating, and propagation loss. Data from these measurements will prove invaluable for further designs to be fabricated and tested in Phase II of the program. For this program, Sensor Unlimited and Sarnoff Corporation will leverage experience gained by successful commercialization of DFB and high-power broad area lasers.
