METHOD AND SYSTEM FOR CONVERTING A MODULATED OPTICAL SIGNAL TO A MODULATED ELECTRIC SIGNAL

摘要

A system for converting a modulated optical signal to a modulated electric signal, the system includes: (a) an optical interface, which is adapted to receive a modulated optical signal, which comprises a carrier signal with a carrier signal frequency, and a modulated optical signal that is superimposed on the carrier signal with a modulated optical signal bandwidth; (b) a substrate; and (c) a thin semi-insulating microstrip, which is coupled to the substrate on one side and to the optical interface on the other side; wherein (a) a depth of the microstrip is of the scale of a penetration depth of the modulated optical signal into the microstrip; (b) an impedance of the microstrip is very responsive to a modulation of the modulated optical signal.
