摘要： An optical wireless local area network using line of sight optical links. The base station and terminal stations are provided with optical transceivers which include a transmitter array and detector array. The transmitter array consists of an array of resonant cavity light emitting diodes integrated using flip-chip technology with a CMOS driver circuit. The driver circuit includes constant bias, current peaking and charge extraction. The driver circuitry is compact and can be confined within a region underlying the corresponding light source. The detector array consists of an array of photo diodes, provided with sense circuitry consisting of a pre-amplifier and post-amplifier. The diodes and sense circuitry are also integrated using a flip-chip technique. The light emitter and the detector may include adaptive optical elements to steer and/or focus the light beams.

摘要： A receiver assembly (100) and data communications method are disclosed. In one arrangement, a receiver assembly (100) comprises a concentration stage (14). The concentration stage (14) receives radiation via an input surface (120) and outputs concentrated radiation via an output surface (122). The concentration stage comprises a wavelength converting member (6) that converts radiation to longer wavelength radiation. An optical element (102) is provided which is such that if a plane wave of radiation is incident on the optical element a spatial distribution of radiation derived from the plane wave on the input surface of the concentration stage varies as a function of a direction of incidence of the plane wave relative to the optical element. A plurality of detectors (42) are provided, each detecting radiation output from a different portion of the output surface of the concentration stage.
