Abstract
We present a newly developed 90-GHz high O/E conversion efficient, high power photoreceiver for radio over fiber transmission, which is driven by photonic power supplies. The photoreceiver consisted of a hybrid integration with a 100 GHz photodetector and a 22-dB high gain RF amplifier. To save the fiber resources in the PoF system, bias-free operational design was employed for the photodetector. In the RF measurement result, we successfully achieved the high output power of +15 -dBm at 90-GHz, high linearity in RF output power against the input photo-current, and high 3dB bandwidth of 14 GHz (85-99 GHz).
