Semiconductor laser, method of driving semiconductor laser, and wavelength conversion element |
| abstract |
A semiconductor laser capable of performing a self-pulsation operation stably at a high frequency is provided. A semiconductor laser is provided with a first conductive type semiconductor substrate, a first conductive type cladding layer, an optical waveguide layer, and a front DFB region provided with a diffraction grating close to the optical waveguide layer. A rear DFB or DBR region 103 having a diffraction grating close to the optical waveguide layer 3 and electrically separated from the front DFB region 101; and a second conductivity type clad formed so as to embed the diffraction grating 5. And the diffraction grating 5 in the DFB region 101 and the diffraction grating in the rear DFB or DBR region 103 have a phase shift portion in part. [Selection diagram] Fig. 1 |
