The program goals were to demonstrate ultra-low noise RF links, and to demonstrate several key integrated optoelectronic components employing a versatile asymmetric twin waveguide technology. All objectives set forth in the proposal were either met or exceeded. These achievements included Demonstration of a versatile integration technology based on the asymmetric twin waveguide platform that allowed for the realization of a broad range of components useful in RF photonic components. This resulted in the demonstration of a fully integrated heterodyne receiver operating to 5 GHz, as well as balance photodiodesemiconductor optical amplifier pairs, and a wavelength tunable laser used as the local oscillator on the ATG platform. In addition we have demonstrated the highest bandwidth heterodyne links operating at 5GHz and 16GHz. These links were based on phase modulation and represent an extremely high sensitivity route to analog optical transmission. Paths to commercialization involve a close partnership Apogee Photonics, Inc., a start up from our group whose charter is to fabricate low cost photonic integrated circuits based on twin waveguide technology.
