ABSTRACT:
An optical transmitter includes a continuous wave optical source for generating an optical signal having a carrier frequency component, a clock modulator for performing a clock modulation upon the optical signal using a clock signal to generate a clock-modulated signal, and a data modulator for performing a data modulation upon the clock-modulated signal using a data signal. The clock signal has a half frequency of that of the data signal. The clock modulator is constructed by a single-end type phase modulator and at least one tap type optical filter.
