METHOD FOR PRODUCING A RESONANT STRUCTURE OF A DISTRIBUTED-FEEDBACK SEMICONDUCTOR LASER

摘要

The invention concerns a method for reproducibly producing a resonant structure of a distributed-feedback semiconductor laser having a narrow waveguide of the order of tens of micrometers, the production of the diffraction grating being carried out after the step of producing the ribbon. In a final step, a diffraction grating is inscribed depending on a desired specific wavelength.
