14.6-GHz LiNbO3 Microdisk Photonic Self-Homodyne RF Receiver
نویسندگان
چکیده
Nonlinear optical modulation combined with simultaneous photonic and RF resonance in an LiNbO3 microdisk modulator is used to create a self-homodyne photonic RF receiver. Carrier and sidebands are mixed in the optical domain, and the modulated optical signal is detected using a photodetector. The photodetector has a bandwidth matched to the baseband signal. It filters out the high-frequency components and generates the baseband photocurrent. Receiver operation is demonstrated by demodulating up to 100-Mb/s digital data from a 14.6-GHz carrier frequency without any high-speed electronic components. A bit error rate of 10 9 is measured for 10-Mb/s downconverted digital data at 15-dBm received RF power. Preliminary results of employing this photonic RF receiver in a short-distance -band wireless link demonstrate the potential of using high-quality optical microresonators in RF receiver applications.

The authors report an enhanced LiNbO3 microdisk photonic microwave receiver modulator with a sensitivity of 3 pW (285 dBm) and a bandwidth of 60 MHz centred at 14.6 GHz. The sensitivity of the modulator is improved by using a critically coupled microwave ring resonator and a modified ground plane for passive E-field amplification and confinement.
