Modified Uni-Traveling-Carrier Photodiode-Based V-Band Optoelectronic Mixers with High Up-Converted Power and High Responsivity

摘要

A modified uni-traveling-carrier photodiode-based V-band optoelectronic mixer is demonstrated which can up-convert intermediate-frequency (IF) signals with both the 59.5 GHz local oscillator (LO) and the IF signals in optical form. By properly choosing the ratio between the injected optical LO and IF signals, a high up-converted signal power of-13.1 dBm was obtained at 30 mA of photocurrent and 1.6 V reverse bias without any cooling operation. When a thermal electric cooler is used, up-converted signal power as high as -4.7 dBm was obtained at 70 mA of photocurrent and 3.5 V reverse bias.
