Patent ID: 7577364

Claim:
An optical wireless LAN comprising at least one base station and a plurality of terminal stations, the at least one base station comprising an optical transmitter providing a line-of-sight optical downlink to transmit data to a terminal station receiver in each of the plurality of terminal stations, wherein each of the plurality of terminal stations is provided with a terminal station transmitter providing an uplink for transmitting data to a base station receiver in the at least one base station, said uplink comprising at least one of an undirected optical link and a radio link, and wherein the optical transmitter comprises: a) an integrated solid state light emitter comprising a two dimensional unit cell array of solid state light sources formed in an emitter layer and superposed on a corresponding two dimensional unit cell array of respective drive circuits formed in a driver layer, each drive circuit for producing a shaped drive signal for the corresponding light source in response to an input logic signal, wherein the surface area of each unit cell of the drive circuit array is less than or equal to the surface area of each unit cell of the light source array, whereby each drive circuit is confined within a region underlying the corresponding light source unit cell; and b) at least one adaptive optical element positioned in the path of light from the light sources.
