Abstract
Provided is a wavelength-tunable external cavity laser module. The wavelength-tunable external cavity laser module includes: a gain medium generating light; an optical waveguide combined with the gain medium and including a Bragg grating and a thin film heater adjusting a temperature of the Bragg grating; and a high frequency transmission medium delivering a high frequency signal to the gain medium, wherein the high frequency transmission medium controls an operating speed of the light.
