Abstract
PURPOSE:To facilitate the coupling of a semiconductor laser and a photo waveguide by a method wherein a well is created in a substrate whereon a photo waveguide has been constructed and the bottom of the well is coated with a metal film and a semiconductor laser chip is fixedly inserted in the well. CONSTITUTION:Ti or the like is diffused into an electro-optical crystal substrate 1 composed exemplifiedly of LiNbO3 or LiTaO3 for the creation of a thin film photo waveguide 2. A part of the waveguide 2 is subjected to plasma etching for the formation of a well 3. Au or the like is evaporated and deposited on the bottom surface of the well 3 to construct an electrode metal film 4. Then a semiconductor laser 5 with a stripe shaped electrode 7 is fitted into the well 3 so that the active layer 6 of the semiconductor laser 5 and the photo waveguide 2 may be in alignment with each other. This method facilitates the coupling of a semiconductor laser with a photo waveguide.
