ABSTRACT:
A laser diode comprises a substrate, a first blocking layer having a groove, an alternate combination of a lower cladding layer and a second blocking layer, an active layer formed in the groove, and an upper cladding layer. A light-amplifying region and a light-absorbing region are formed alternately in the waveguide. Both regions are disposed periodically at a period corresponding to bragg wavelength.
