A polarization-independent silicon light intensity modulator for 1.32 mu m fiber optics

The authors have developed an integrated silicon light intensity modulator based on polarization-independent free-carrier optical phase modulation and mode filtering in fibers. A novel push-pull complementary diode pair are used for a twofold increase in modulation depth over a single diode device. Operation is demonstrated at a wavelength of 1.32 mu m.<
