Abstract: 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.

Abstract: A polarisation control device having a polarisation converter (22) in a first section (B)of an optical waveguide (15) with a gradually varying asymmetrical cross - sectional (transverse) profile and an active phase shifter (38) in a second section (C) of the optical waveguide whose birefringence is adjustable by a relative phase controller. The polarisation converter (22) converts an orthogonal fundamental mode (TE or TM) into a hybridised signal present in the active phase shifter (38). The first and second sections (B, C) of waveguide are joined to one another to form a single continuous waveguide (15), which can significantly reduce interfacial reflections.

Abstract: An optical amplifier comprising a signal semiconductor optical amplifier (SOA) (1) and a control SOA (2) in an optical circuit comprising a signal path (4) passing through the signal SOA (1) and a laser cavity containing both the signal SOA (1) and the control SOA (2). The control SOA (2) may be arranged outside the laser cavity so that it does not amplify a signal in the signal path (4). Alternatively, the control SOA (2) is arranged in the signal path (4), but has insignificant gain in the predetermined signal band (3) so that it does not amplify a signal passing along the signal path (4). The laser cavity clamps the total gain of the signal SOA (1) and the control SOA (2). In use, the bias current supplied to the control SOA (2) is varied to control the clamped-gain of the signal SOA (1). Therefore the gain of a signal passing along the signal path (4) is clamped to a level which may be varied by control of the control SOA (2). In an alternative type of embodiment, a similar type of control is achieved in a structure integrated in a single semiconductor chip. In particular a waveguide (56) extends along a signal active layer (52) and a laser cavity arranged perpendicularly to the layered structure of the semiconductor chip contains both the signal active layer (52) and a control active layer (59) which corresponds to the control SOA (2).

Abstract: A polarisation control device having a polarisation converter in a first section of optical waveguide with a gradually varying asymmetrical cross-sectional (transverse) profile and an active phase shifter in a second section of optical waveguide whose birefringence is adjustable by a relative phase controller. The polarisation converter converts an orthogonal fundamental mode (TE or TM) into a hybridised signal present in the active phase shifter. The first and second sections of waveguide are joined to one another to form a single continuous waveguide, which can significantly reduce interfacial reflections. The invention teaches the introduction of a selectable degree of asymmetry to a section of planar optical waveguide after growth of that waveguide to form the polarisation converter. This feature enables the use of lower efficiency mode convertors to give far greater control over fabrication tolerances, leading to increased yield.
