    摘要: A semiconductor laser element includes, on a substrate, at least a first conductive type first clad layer, an active layer, a second conductive type second clad layer, a current block layer having a stripe-shaped deficient portion extending in a direction of a resonator, a second conductive type third clad layer buried in the stripe-shaped deficient portion of the current block layer and a second conductive type protection layer provided on the third clad layer. The active layer includes at least a window region adjacent to its one end surface and an internal region having a quantum well structure, and a portion opposite to the internal region is irradiated with an ionized atom from a surface of a layer arranged on the second conductive type second clad layer side and thereafter subjected to heat treatment to form the window region. A peak wavelength λw of photoluminescence from the window region of the active layer has a relation of: λw≦λi−5 nm with respect to a peak wavelength λi of photoluminescence from the internal region of the active layer, and a half-width of the photoluminescence from the window region is narrower than a half-width of the photoluminescence from the internal region.

    摘要: In a semiconductor laser device having a quantum well active layer, an undoped thin spacer layer is formed between an undoped optical guide layer and a p-type cladding layer. The thickness of the spacer layer is preferably 5 nm or more but less than 10 nm. The spacer layer absorbs impurities diffusing thereinto from the p-type cladding layer. Thus, the dopant is prevented from being diffused into the undoped optical guide layer.

    摘要: A buried stripe type semiconductor laser device having a mesa stripe whose side faces are {111} facets and having a current confinement structure under epitaxial layers burying the mesa stripe is disclosed. The buried stripe type semiconductor laser device comprises a (100) semiconductor substrate having a stripe-shaped ridge in the direction, a multi-layer film of a double hetero structure formed on the upper surface of the stripe-shaped ridge. The mutil-layer film includes a laser oscillating active layer of a smaller width than that of the stripe-shaped ridge. The current confinement means are formed at both sides of the mesa stripe on the semiconductor substrate. In addition, a method of fabricating a buried stripe type semiconductor laser device having no raised portion above a mesa stripe of a substrate is disclosed. The laser device can be mounted in position with the epitaxial layer side down, without the mesa stripe being damaged or strained.
