The laser device preferably has cavity lengths greater than 1000 &mgr;m, and compressive strain multi-quantum well active layer, and front-facet reflectivity of less than about 4%. Higher optical outputs and longer cavity lengths are achieved.

The laser device preferably has cavity lengths greater than 1000 μm, and compressive strain multi-quantum well active layer, and front-facet reflectivity of less than about 4%. Higher optical outputs by longer cavity lengths are achieved. Preferred modules use these laser diodes with external wavelength-selective reflectors that have narrow bandwidths of 3 nm or less, and which include a plurality of longitudinal mode subpeaks within the bandwidth. Relationships between reflectivity value of the front facet and the peak reflectivity of the wavelength-selective reflector for long cavity length laser device are also disclosed, with the relationships providing higher output power along with a stabilized output spectrum.

摘要： A semiconductor laser device having two active-layer stripe structures includes an n-InP substrate, an n-InP clad layer, a lower GRIN-SCH layer, an active layer, an upper GRIN-SCH layer, a p-InP clad layer, and a p-InGaAsP contact layer grown in this order, in a side cross section cut along one of the stripe structure. A high-reflection film is disposed on a reflection-side end surface, and a low-reflection film is disposed on an emission-side end surface. A p-side electrode is disposed on only a part of the upper surface of the p-InGaAsP contact layer so that a current non-injection area is formed on an area absent the p-side electrode.

摘要： The present invention provides a method for hermetically sealing a semiconductor laser element, by which the cleanness of a package can be maintained extremely satisfactorily in a stabilized state, in order to prevent organic substances from being adhered to the end faces of high output semiconductor laser elements due to photochemical actions. The method comprises the first step of introducing oxygen into a chamber of a hermetical-sealing apparatus and irradiating ultraviolet rays onto an unsealed package having a semiconductor laser element mounted, in the chamber, and the second step of purging the chamber with an inert gas and hermetically sealing an unsealed package in the inert gas atmosphere without being exposed to the outer atmosphere.
