Abstract: An optical beam splitter arrangement comprising two beam splitter mounts one of which is turnable relative to the other by flexing a deformable connection. By controlling the turn angle of rotation it is possible to use the light reflected by one of the beam splitters to monitor the output power of a laser and to use the light reflected by the other beam splitter to monitor the wavelength transmitted by the laser.

Abstract: A multimode optical fibre communications system, and in particular to a system in which non-linearities in the propagation of the signal through a multimode optical communications channel degrade the signal presented to the receiver. The system includes an optical transmitter unit for connection to a multimode optical fibre transmission link. The transmitter unit has a data input for receiving an input data signal, a data signal processing circuit and a source of optical radiation. The data signal processing circuit is arranged to receive the input data signal from the data input and to provide a processed data signal to the source of optical radiation and the source of optical radiation is arranged to generate from this an optical signal for transmission by a multimode optical fibre. The data processing circuit is arranged to provide from the input data signal a non-inverted data signal and an inverted data signal, receive a control signal for controlling the generation of the processed data signal, apply a controllable delay in accordance with the control signal to at least one of the non-inverted and inverted data signals, and combine the non-inverted and inverted signals after the application of the controllable delay(s) and gain factor(s) to generate the processed data signal.

Abstract: A laser located within a casing of an optoelectronic module is operated by heating the laser to an operating temperature at or above the maximum specified, operating temperature of the module casing using a heater device within the module, the laser having operating characteristics at its operating temperature that are sufficient for its required function. The heater device can be separated from the module casing by an insulating layer or by a thermal switch. The thermal switch can include a droplet of thermally conductive fluid displaceable between a first position where it provides a low thermal impedance path between the heater device and the module casing and a second position wherein a high thermal impedance path is provided between the heater device and the module casing.

Abstract: A method for aligning optical components in an optical assembly. The method comprises the steps of pre-aligning the optical fiber to the optical device, measuring a coupling efficiency of the optical fiber to the optical device, applying energy to a support means, the energy being sufficient to enable the support means to become ductile, and applying a force to the support means in a direction which increases the coupling efficiency.
