Abstract: A method and system for optical communication with between a device and a remote station include passing light incoming from the remote station and outgoing to the remote station through a lens system and an aperture of the device, for example the lens system comprising a Plössl lens or a double-Gauss lens. The method and device include receiving the incoming light at an optoelectronic assembly that has an array of VCSELs, an array of microlenses, and a plurality of photodetectors configured to generate an output signal in response to detected light. The VCSELs may be arranged in clusters for simultaneous emission, and multiple clusters may also be activated for simultaneous emission.
