Abstract :
The authors report an enhanced LiNbO3 microdisk photonic microwave receiver modulator with a sensitivity of 3 pW (-85 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.
