Ridge waveguide type distributed feedback semiconductor laser device and method for manufacturing the same |
摘要 |
A ridge waveguide type distributed feedback semiconductor laser device includes a diffraction grating formed on a surface of a semiconductor wafer, a semiconductor layer formed on the diffraction grating, the semiconductor layer serving to alleviate the irregularity of the diffraction grating, and a stripe-like ridge having a cladding layer and a contact layer formed on the semiconductor layer. Also, a method for manufacturing the ridge waveguide type distributed feedback semiconductor laser device is disclosed.
