英文摘要 | PURPOSE:To stabilize both optical output and wavelength for the titled laser by a method wherein, in the case of the wavelength sweeping laser with a duplex feedback loop, an optical output detecting section and a wavelength detecting section are integrated on the same substrate. CONSTITUTION:The wavelength sweeping laser consists of a wavelength controlling type semiconductor laser 1 provided on the same substrate, an optical output detector 3, a wavelength detector 4, and amplifiers 5 and 6. In this constitution, the laser 1 and a detector 2 are formed on the same substrate. To be more precise, a laser section 20 and an optical output detecting section 30 are provided adjacently, and between them, an insulating layer 23 is provided by performing a chemical etching or an irradiation of proton. Also, on the detecting section 30, a terminal that will be used to apply inverted bias is installed, a waveguide passage 10 with periodic structure is formed on the laser section 20, and an N type GaAa active layer 13 is formed in the center part having no periodic structure. Subsequently, electrodes terminals 11 and 14 are provided respectively on the layer 13 and the periodic structure, and the light emitted from the waveguide passage 10 is incidented into the detecting section 30. |
