OPTICAL AMPLIFIER BASED ON ELECTRO-OPTIC EFFECT FOR ELECTRICAL SIGNALS AND ITS APPLICATION AS SEMICONDUCTOR RADIATION DETECTOR PREAMPLIFIER

摘要

An amplifier for amplification of an electrical signal comprises an electro-optic (EO) medium for receiving the electrical signal, wherein applying the electrical signal to the EO medium causes a change to an effective index of refraction, a device configured for measuring a light phase change for measuring the change to the effective index of refraction, and a photodetector configured to convert the change to the effective index of refraction into an amplified electrical current output signal.
