ABSTRACT:
An optical transmitter that multiplexes a plurality of signal light each having less chirp characteristic by the CML technique is disclosed. The optical transmitter comprises a plurality of optical modules, a plurality of TEC controllers each driving the TEC in the optical module, a de-multiplexer that de-multiplexes the output of respective modules, an etalon filter, and a monitoring unit that monitors the component of the signal light output from respective modules. The TEC controller controls the temperature of the LD in the module such that two emission wavelengths of the LD each corresponding to the ON level and the OFF level is set in both side of one of the critical wavelengths of the etalon filter where the transmittance thereof becomes a maximum.
