摘要
Provided is a quarter-wavelength shifted distributed feedback laser diode. The laser diode includes a substrate having a laser diode section and a phase adjustment section, a waveguide layer on the substrate, a clad layer on the waveguide layer, a grating disposed in the clad layer in the laser diode section, an anti-reflection coating disposed on one side walls, of the substrate, the waveguide layer, and the clad layer, adjacent to the laser diode section, and a high reflection coating disposed on the other side walls, of the substrate, the waveguide layer, and the clad layer, adjacent to the phase adjustment section.
