摘要： A surface-emitting semiconductor laser device is provided that includes an edge-emitting laser integrated in a semiconductor material with various reflectors and a diffractive lens. The edge-emitting laser has a first section comprising an active MQW region, a second section comprising a passive region and a third section comprising a semi-insulating or un-doped semiconductor bulk layer. This configuration ensures that the injection current will pass through all of the layers of the active region, thereby preventing the occurrence of optical losses due to un-injected areas of the MQW active region. In addition, the inclusion of the passive region ensures that there is no current passing through the interface between the active MQW region and the regrown semiconductor bulk layer. The latter feature improves performance and device reliability.

摘要： A semiconductor laser device includes an edge-emitting laser monolithically integrated with a diffractive lens formed on the chip surface to emit a focalized or collimated beam in a direction perpendicular to the surface. An upper reflective surface and an angled reflective surface are formed in the chip upper surface. A lower reflective surface is formed in the chip lower surface. The laser, angled reflective surface, upper reflective surface, lower reflective surface and diffractive lens are oriented in relation to one another so that a first portion of the light emitted by the laser impinges directly upon the upper reflective surface, which reflects it onto the angled reflective surface, while a second portion of the light emitted by the laser impinges directly upon the angled reflective surface. The angled reflective surface reflects the light portions onto the lower reflective surface, which in turn reflects them through the diffractive lens.

摘要： A fiber stub assembly is provided that has a cladding layer that is reduced in diameter near the end of the stub into which light is launched from a light source. The portion of the stub having the cladding layer with the reduced diameter is surrounded by a light-absorbing material that is in contact with the inner surface of the ferule and with the outer surface of the cladding layer. The light-absorbing material and the outer surface of the cladding layer have indices of refraction that are matched, or very close to one another, such that any modes of light that are propagating in the cladding layer that impinge on the interface propagate into the light-absorbing material and are absorbed thereby. The reduced diameter of the cladding layer and the surrounding light-absorbing material form a pin hole opening through which light is received. The pin hole opening makes it possible to use a simple ball lens to focus light from the light source into the end of the fiber stub to thereby reduce the number of modes that are dispersed into the cladding layer.

摘要： To determine the polymerization profile of a layer of polymeric material, particular a coating of an optical waveguide, a source sends a light radiation towards the layer under test at different angles of incidence, and both the portion of radiation reflected by the layer and the portion transmitted by the layer are converted into electrical signals. The electrical signals are supplied to devices for measuring their intensity, and a processing system processes the intensity values to obtain a value of the refractive index at a different depth inside the layer and to obtain the degree of polymerization at each depth by comparison with the values of the refractive index of a precursor of the polymer and of the fully polymerized material.
