| Abstract(in English) | Oscillation wavelength of distributed feedback semiconductor lasers varies from device to device due to inevitable fabrication error. Therefore, selection from a number of devices as well as external tuning of wavelength is necessary for practical use. In order to manage this problem, we have proposed a new concept of wavelength trimming technology where the oscillation wavelength is adjusted without using external active control circuitry. We have made use of photo-absorption induced disordering of quantum wells for wavelength trimming and realized 0.36nm adjustment in a 1.55μm ridge waveguide DFB laser |
