摘要： An optical subassembly includes a substrate, a heat spreader, and a submount. The submount has a submount mounting surface and a component mounting surface with either the submount mounting surface or the component mounting surface including an angle. The submount is positioned on either the heat spreader or the substrate such that the component mounting surface is positioned at the angle relative to the substrate. An optoelectric device is positioned on the component mounting surface and coupled to interconnects on the substrate. The optoelectric device is thermally coupled to the heat spreader through the submount to provide a low thermal resistance between the optoelectric device and the heat spreader. An encapsulant structure is mounted on the substrate and hermetically encloses the optoelectric device. The encapsulant structure includes a window positioned to pass light between the optoelectric device and an externally mounted optical fiber.

摘要： A Mach-Zehnder interferometer modulator for modulating a beam of laser light includes a pair of separate waveguides through which the laser light is passed after splitting in a splitting zone and after which the light is recombined in a merge zone. The waveguides are formed in a semiconductor material with one of the electrodes of each pair being formed in a doped layer while the other electrode, the top electrode, is a surface metalisation. The doped layer is trenched so that adjacent electrodes in the doped layer are electrically isolated from one another so that one of the electrodes in the doped layer can be connected with a different electrical polarity to the other electrode in the doped layer thereby permitting the connection of the pairs of electrodes in parallel anti-phase mode.

摘要： An EDF amplifier comprises two EDF loops separated by optical isolators and pumped with light by pump laser diodes under the control of an output power control system. To achieve the required output power the current supplied to the pump supplying light to the input loop is set to the maximum drive current Imax for the pump laser, and the pump currents of all pumps not supplying light to the input loop, that is the pumps supplying light to the further loop or loops, are adjusted to achieve the required output power. To avoid a very high MPI, the inversion of all loops is never so low that the gain in the first loop has to compensate for loss in the following loop or loops. This is done by providing a minimum pump power to the second loop and any following loops. This ensures that the loops are always inverted enough, and that they do not exhibit too much loss. The required minimum pump current is obtained by modelling and experimental verification.

摘要： A method for integrating optical devices in a single growth step by utilizing a combination of Selective Area Growth and Etch (SAGE) is provided. An first device is formed between a set of oxide-masked regions, whilst a second device is formed in an adjacent planar region. By use of Selected Area Growth and Etch (SAGE), in which the growth between the oxide-masked regions is greater than the growth in the planar region, and in which the etch rate in the area between the oxide-masked regions is substantially the same as that in the planar region, the number of active quantum layers for the first device are formed between the oxide-masked regions, and a different number of layers for the second device is formed in the planar region.
