Low-Cost, High-Performance Analog Optical Links
Abstract
Photonic Systems, Inc. pursued the goal stated in the RF Lightwave Integrate Circuits' (RFLIC's) BAA ("...achieving a Vpi in the range of 0.1 to 0.5 Volts [to enable a link having] zero RF insertion loss with 1 - 10 mW of optical power available from conventional laser diode sources") on two parallel development paths. Collaborating with Sarnoff Corporation, Photonic Systems developed a Bipolar Cascade Laser that achieved a slope efficiency of 0.5 W/A by forcing the link's input RF signal to feed a series-connected succession of multiple laser junctions whose optical outputs are collected in parallel to illuminate the link's single photodetector. Additionally, Photonic Systems developed a Broad Bandwidth Resonant Modulator, in which two low-loss optical resonators act as a lever to reduce the effective Vpi by 25% for a Vpi=2.7V of the interferometric optical intensity modulator process relative to the Vpi of the optical phase modulator embedded within the two resonators.
