摘要： To make a grating substructure in semiconductor material for use in a DFB laser, a first layer of semiconductor material is doped at a first doping concentration. A second layer of the semiconductor material is formed over the first layer. The second layer is doped higher concentration than the first layer and sufficiently different to change the refractive index of the semiconductor material. A third layer doped at a concentration comparable with the first layer is formed over the second layer. An etch is performed through a mask to form spaced etched regions extending at least through the second and third layers. Then a further layer of the semiconductor material doped at a doping concentration comparable the first and third layers is overgrown on the wafer. This results in a composite layer of the semiconductor material doped at a low doping concentration containing spaced islands of the semiconductor material doped with a dopant at a high doping concentration and having a different refractive index from the composite layer. The semiconductor material is preferably silicon-doped InP.

摘要： An integrated optical package comprises an integrated optical device supported on a carrier with a gelatinous material therebetween to assist in heat conduction. The carrier can include a thermal regulating device such as a heat sink or heater for regulating the temperature of the integrated optical device via the gelatinous material. The gelatinous material can include a metallic second phase suspended in the gelatinous material, to improve its thermal conductivity. The maximum dimension of the particles is ideally smaller than the gap between the integrated optical device and the carrier in which the gelatinous material is located, such as in the 5 to 95 percent range of the dimension of the gap. The particles of the metallic second phase can be elongate, in which case they can be aligned with each other such as in a direction extending from the integrated optical device towards the carrier. Alternatively, they can be substantially spherical. Ferromagnetic particles are easier to align by using a magnetic field. A method is also disclosed, comprising the steps of disposing a closed loop of adhesive, thus forming a well, on one or the other of the integrated optical device or the carrier, placing a gelatinous material into said well, placing the other of the carrier or integrated optical device in contact with the adhesive layer and gelatinous material, and curing the adhesive to secure the integrated optical device to the carrier. The gelatinous material can be thixotropic.

摘要： Semiconductor laser diodes, particularly broad area single emitter (BASE) laser diodes of high light output powers are commonly used in opto-electronics. Light output power and stability of such laser diodes are of crucial interest and any degradation during normal use is a significant disadvantage. The present invention concerns an improved design of such laser diodes, the improvement in particular significantly minimizing or avoiding (front) end section degradation at very high light output powers by controlling the current flow in the laser diode in a defined way. This is achieved by controlling the carrier injection, i.e. the injection current, into the laser diode in a novel way by creating single current injection points along the laser diode's longitudinal extension, e.g. along the waveguide. Further, the supply current/voltage of each single or group of current injection point(s) may be separately regulated, further enhancing controllability of the carrier injection.
