EXTERNAL CAVITY TUNABLE LASER MODULE |
摘要 |
Provided is a wavelength tunable external cavity semiconductor laser module by a thermo-optic effect of a semiconductor optical waveguide. The wavelength tunable external cavity semiconductor laser module includes: a light source generating wideband light; a semiconductor optical waveguide having one end optically coupled to the light source; a Bragg grating formed on the optical waveguide; a thin film heater provided at an upper portion of the Bragg grating and controlling a reflection band of the Bragg grating by a thermo-electric effect; a first temperature sensor provided at an upper portion of the optical waveguide; a thermoelectric cooler (TEC) provided at a lower portion of the optical waveguide; a heat insulating layer provided between the optical waveguide and the TEC; and an optical fiber optically coupled to the other end of the optical waveguide. |
