Abstract
Provided is a tunable laser module emitting an optical signal having high speed, high power and wideband wavelength tuning. The tunable laser module includes a laser array configured to emit an optical signal having a plurality of different lasing wavelengths, a temperature controller configured to change a temperature of the laser array, and an optical integration device configured to modulate or amplify the optical signal at a side of the laser array opposing the temperature controller.
Claims9
A tunable laser module, comprising:
- a laser array configured to emit an optical signal having a plurality of different lasing wavelengths;
- a temperature controller configured to change a temperature of the laser array;
- a substrate separated from the laser array and the temperature controller;
- and
- an optical integration device configured to modulate or amplify the optical signal at a side of the laser array opposing the temperature controller;
- wherein the optical integration device is formed as one body including a plurality of components sharing the substrate.
