摘要： The invention provides a chemical etching method for a semiconductor device, which comprises a step of forming a first layer of Ga.sub.1-x Al.sub.x As (0.ltoreq.x . The slope angle of etch face of the second layer depends on the mol fraction y of the second layer, and the slope angle of etch face of the first layer depends on the mol fraction y of the second layer and the mol fraction x of the first layer. These facts are best utilized in the invention so that the etch profile of the first layer may have a desired slope angle. By utilizing this chemical etching method it is possible to produce by chemical etching a semiconductor laser having a flat cavity facet perpendicular to a junction; it is also possible to provide an inner stripe type semiconductor laser having grooves whose side walls are perpendicular.

摘要： In a laser of such type that the distribution of the effective refractive index varies in a direction which is along the face of its active layer and perpendicular to the direction of the laser light transmission, thereby defining the active region to be between a pair of refractive index changing zones, the refractive indexes of a pair of end surfaces of a laser resonator (i.e. the active region) is made smaller than the intrinsic refractive indexes of the cleavage face of the active layer.

摘要： On an n-type semiconductor substrate having a ridge part of stripe-shaped pattern, the following layers are formed by liquid phase sequential epitaxial growth: an undoped active layer; a p-type clad layer; and an n-type isolation layer. Thereafter, a Cd impurity is diffused in the isolation layer in a stripe-shaped pattern at the position above the ridge part, thereby forming a p+-type conduction region in the central part of the isolation layer. By forming the stripe-shaped ridge part on the substrate overriding the active layer, the injected current is effectively confined to the lasing region which is the thinner part of the active layer and is on the ridge part. Therefore the threshold current is decreased. Accordingly, the light lased in the active layer is effectively confined in a stripe-shaped lasing region thereof, and a stable transverse mode of lasing is obtainable.

摘要： Rubber compositions curable to rubbery elastomers by heating are provided, in which co-vulcanization of an organic rubber, e.g. natural rubber or an organic synthetic rubber and an organopolysiloxane rubber can be effected to a satisfactory degree, whereas such co-vulcanization in the prior art involves several difficult problems. The characterizing components in the rubber composition are the organopolysiloxane which has at least two functional units of either mercapto groups or aliphatically unsaturated linkages in the molecule and a specific organosilicon compound which has a polysulfide linkage and one or more silicon-bonded hydroxy groups or hydrolyzable atoms or groups in the molecule.
