Semiconductor laser device and method for fabricating the same
摘要:
A semiconductor laser device includes a MQW active layer, a p-type cladding layer formed on the MQW active layer, having a ridge portion and having a smaller refractive index than that of the MQW active layer, a plurality of dielectric films formed at least on part of the p-type cladding layer extending from each side of the ridge portion.
