摘要： A semiconductor optical device comprises an active waveguide having a tapered portion, and a passive waveguide extending beyond the end of the active waveguide and optically coupled to the tapered portion of the active waveguide. The passive waveguide beyond the end of the active waveguide supports an optical mode of larger size than the optical mode supported by the active waveguide. The tapered portion of the active waveguide is truncated and the separation between the active waveguide and the passive waveguide is greater than in previously known devices in order to minimize or at least reduce the truncation loss at the truncation.

摘要： A fibre-optic module incorporating a semiconductor optical amplifier is compatible with a standard specification for a fibre-optic transceiver module, which is typically pluggable. The module comprises optical connectors capable of connection to first and second optical fibres and being in accordance with said standard specification and the input optical signal received from the first optical fibre is amplified by the semiconductor optical amplifier and supplied to the second optical connector for transmission along the second optical fibre. The module further comprises an electrical parallel connector having a physical configuration in accordance with said standard specification and a control circuit which receives control signals from the electrical parallel connector and to control the operation of the optical amplifier. Thus the module maybe connected to a standard electrical backplane alongside fibre-optic transceiver modules to augment the optical performance of the transceiver modules.

摘要： An optical amplifier is disclosed comprising a signal semiconductor optical amplifier having a waveguide, forming at least part of a signal path between an input and an output, extending along a signal active region for amplification of a signal. The amplifier also includes a control active region of semiconductor material having a gain which is controllable independently from the gain of the signal active region. The amplifier also includes a laser cavity containing both the signal active region and the control active region and being capable of clamping the gain of the signal active region, and the control active region is arranged not to amplify a signal in the signal path within a predetermined signal band.
