Abstract :
Millimeter-wave generation by photomixing at 1.55 μm in long-wavelength velocity-matched distributed photodetector (VMDP) is experimentally demonstrated. The VMDP exhibits a dc responsivity of 0.25 A/W, a breakdown voltage of 7-9 V, and up to 15-mA dc photocurrent without damage. Millimeter-wave output powers of -21 dBm at 75 GHz and -24 dBm at 95 GHz were measured.
