    摘要: A method for producing a semiconductor laser having an edge window structure includes the steps of forming masks of insulating films on a nitride-based III-V compound semiconductor substrate including first regions and second regions periodically arranged in parallel therebetween; and growing a nitride-based III-V compound semiconductor layer in a region not covered by the masks. The first region between each two adjacent second regions has two or more positions, symmetrical with respect to a center line thereof, where laser stripes are to be formed. The masks are formed on one or both sides of each of the positions where the laser stripes are to be formed at least near a position where edge window structures are to be formed such that the masks are symmetrical with respect to the center line. The nitride-based III-V compound semiconductor layer includes an active layer containing at least indium and gallium.

    摘要: A method for manufacturing a semiconductor laser includes the steps of forming a mask layer having a stripe-shaped mask portion corresponding to a ridge stripe to be formed on a nitride-based group III-V compound semiconductor layer, etching the nitride-based group III-V compound semiconductor layer to a predetermined depth using the mask layer to form the ridge stripe, forming a resist to cover the mask layer and the nitride-based group III-V compound semiconductor layer, etching-back the resist until the stripe-shaped mask portion of the mask layer is exposed, removing the exposed mask portion of the mask layer by etching to expose the upper surface of the ridge stripe, forming a metal film on the resist and the exposed ridge stripe to form an electrode on the ridge stripe, removing the resist together with the metal film formed thereon, and removing the mask layer by etching.
