英文摘要 | PURPOSE:To narrow the width of an oscillating spectrum and to stabilize a frequency by regulating an effective light length from a reflecting return light wavelength selecting and laser light emitting end face to a grating waveguide in the waveguide by utilizing electro-optical effect of a quantum well structure semiconductor in the waveguide. CONSTITUTION:A light emitted from laser light generating means 1 arrives at a grating waveguide 23 through a light waveguide 19 of a quantum well structure formed in a semiconductor substrate 20, only the light having a wavelength selected by a filtering function of the waveguide 23 is reflected, and emitted from laser light generating means 1 through an optical waveguide 22. Here, effective light length from the emitting end face of reflecting return light wavelength selecting and laser light emitting means 1 of the waveguide 2 to the waveguide 23 can be electrically controlled by applying suitable voltages VB, VP to an electrode 14, thereby obtaining extremely narrow stable spectrum. |
