Title: Optical transmitter
Inventor: TANAKA TOSHIKI
IPC: H04B10/43
Filed: 2011-03-10
Abstract: PROBLEM TO BE SOLVED: To provide an optical transmitter capable of applying different modulation rates between sub carriers, and coping with changes in a transmission distance and the like.SOLUTION: A clock signal from one reference clock is frequency-converted and supplied to a regular-interval optical frequency comb generator and modulation parts of optical modulators. A frequency interval of a generated frequency comb can be changed by changing an electrical frequency of the clock signal to the regular interval optical frequency comb generator, and an irregular interval frequency comb can be generated by selectively using only a specific optical frequency of continuous light of the generated frequency comb. In addition, a modulation rate can be changed by changing a clock frequency of a driving signal to be given to the optical modulator. By using the clock signal from the one reference clock, the frequency interval of the frequency comb and the variation of the modulation rate are synchronized.
