Abstract :
A balanced velocity-matched distributed photodetector (VMDP) with both impedance and velocity matching has been designed and successfully fabricated. Preliminary experimental results shows that the relative intensity noise has been suppressed by 12-dB, and the signal has been enhanced by 6-dB. This was the first integration of high power and high speed balanced detectors with a slow microwave transmission line to be used in high performance RF photonic links.
