摘要： A wavelength-locked, integrated optical signal source structure using a semiconductor laser device is disclosed. The optical source structure has a semiconductor laser formed on a semiconductor substrate, and an etched portion coupled with an output end of the semiconductor laser. The etched portion is configured to pass on a first amount of light beam radiated by the semiconductor laser, and to reflect a second amount of light beam by a given reflection angle. A multiple microcavity is formed in a position spaced apart from the etched portion, and the first amount of light beam is incident upon the multiple microcavity. The optical source structure has a first optical detector for detecting the first amount of light beam passing through the multiple microcavity, and a second optical detector for detecting the second amount of light beam reflected by a slanted, reflecting surface portion of the etched portion. The relative change in the light intensity in the first and second optical detectors is measured out to maintain a constant optical wavelength.

摘要： A method for manufacturing the semiconductor laser device comprising the steps of sequentially forming an active layer, a photo-waveguide layer, a cladding layer, and an ohmic contact layer on an upper surface of an InP substrate; forming a first patterned dielectric layer on the ohmic contact layer; depositing a patterned photoresist on the ohmic contact layer to define a p- electrode stripe layer; forming the p- electrode stripe layer only on a part of the ohmic contact layer; performing an annealing process; etching back the layers until the photo-waveguide layer is exposed, using the first patterned dielectric layer and the p- electrode stripe layer as an etching mask, to form a ridge; depositing a second dielectric layer on the substrate formed thus; selectively removing the second dielectric layer to form a contact hole on the p- electrode stripe layer; coating a bonding pad metal layer on the second dielectric layer and in the contact hole; and coating an n- electrode metal layer on bottom surface of the substrate. Since ohmic contact resistance is lowered, thermal generation and threshold current of oscillation are decreased. As a result, operating characteristics of the laser device can be largely improved.
