    摘要: A semiconductor laser includes an n-type semiconductor substrate, an n-type clad layer, an active layer, a p-type first clad layer, a current blocking layer, a p-type second clad layer and a p-type contact layer stacked in this order form the bottom. A p-side ohmic electrode is formed on the p-type contact layer and an n-side ohmic electrode is formed on a back surface of the n-type semiconductor substrate. A stripe is formed in the current blocking layer so as to extend in the optical oscillator direction. In a center portion of the p-type contact layer, a slit is formed so as to extend in the optical oscillator direction and intersect with the stripe with right angles.

    摘要: A method for manufacturing a semiconductor laser. As a preparative step for coating an end face of a resonator with a dielectric film, a cleavage plane of a semiconductor laminated structure that is to be the end face is subjected to a plasma cleaning to prevent a conductive film, which absorbs laser light, from attaching to the cleavage plane. During the plasma cleaning, a first process gas containing argon gas and nitrogen gas is introduced into a vacuumed ECR sputtering apparatus. After the cleavage plane is exposed to the first process gas in the plasma state for a certain time period without application of a voltage, a second process gas containing argon gas and oxygen gas is introduced, and the cleavage plane is exposed to the second process gas in the plasma state while a voltage is applied to the silicon target.

    摘要: A semiconductor laser includes an active layer formed on a substrate and a pair of cladding layers sandwiching the active layer. On at least one of resonator end faces of the semiconductor laser, a first dielectric film with hydrogen added therein is provided. Between the first dielectric film and the resonator end face, a second dielectric film for suppressing the diffusion of hydrogen is provided. Even when a semiconductor laser with an end face coating film including a hydrogen-added film is exposed to high temperatures, peeling of the end face coating film and deterioration of the end face coating film can be suppressed.
