Summary:
Microwave down-converters play an important role in many applications such as wireless communication, radars, and radio-over-fiber systems. Photonic microwave down-converters have attracted much interest recently because of their inherent advantages, including low conversion loss, broad bandwidth, and good electromagnetic interference immunity. When semiconductor lasers are subjected to strong external optical injection, stable-locking dynamics can be induced. In this paper, a highly efficient harmonic microwave down-conversion scheme using semiconductor lasers at stable-locking dynamics is proposed and experimentally demonstrated. The proposed scheme provides a conversion gain of more than 25 dB over a frequency range of 4 GHz without phase noise deterioration.
