"Fast, widely-tunable frequency-agile lasers have the potential of delivering dramatic improvements in capacity, capability, robustness, compactness, and cost in fiber optic communications and sensing systems, for both military and commercial applications.The SGDBR (Sampled Grating Bragg Reflector)… More

For future satellite to ground optical links, large-area high-performance photodetectors are a key component. The APD is a natural choice, owing to its inherent sensitivity advantage compared to photodetectors that do not provide internal gain. Theoutput of Phase I of this program is an APD design… More

Optical networks that operate in harsh environments such as those on military aircraft can benefit from networking equipment having Built-In-Test (BIT) functionality to assist in determining potential network failure points. A BIT functionality isgenerally not present in commercially available… More

A widely tunable universal wavelength-division-multiplexed (WDM) transmitter will be a key technology for advanced battlespace platforms requiring the interconnection of a large number of sensors, data processors, and data storage equipment. In such adynamic WDM network, wavelengths are allocated… More

For future satellite to ground optical links, large-area high-performance photodetectors are key components. Phase I of this SBIR program has produced an APD design that incorporates low noise, Impact Ionization Engineering (I2E) technology, patented by the University of Texas and exclusively… More

A compact, high-performance, low cost optical transmitter chip comprised of a widely-tunable laser, monolithically integrated with an array of semiconductor optical amplifiers and elelectroabsorption modulators, is a key component of an optical source suitable for arbitrary waveform generation in a… More

High-performance, radiation-hard, widely-tunable integrated laser/modulator chip and large-area avalanche photodetectors (APDs) are key components of optical transmitters and receivers that can dramatically lower the barriers to deployment and operation of high capacity in-space optical… More

This SBIR project plans to develop a WDM transmitter qualified for the harsh environment of military and aerospace avionics applications. The fiber pigtailed transmitter will employ a Sampled Grating Distributed Bragg Reflector (SGDBR) InP laser to achieve a data rate of 310Gb/s. The laser will be… More
