Abstract :
Experimental results on an all-silicon optical modulator integrated into a SOI micro-waveguide are reported. A boron doped layer is embedded in the intrinsic region of a PIN diode, and carrier depletion is obtained by applying a reverse bias on the diode. Contrast ratio about 10 dB and insertion loss of 5 dB have been measured. A 3 dB bandwidth larger than 1 GHz is obtained with a 4 mm long phase shifter in a Mach-Zehnder interferometer.
