Smart pixels for optical wireless applications
Optics InfoBase Conference Papers (1997) 265-271
Abstract:
Most smart pixel systems use optical channels that are highly directed; Care is taken to use efficient optical paths that transfer as much energy as possible from source to detector. In this paper we describe the use of highly inefficient 'loosely directed' optical channels in wireless local area networks, and how smart pixel integration techniques can be applied to such systems. An overview of the system and its operation is presented. Techniques for meeting eyesafety regulations at the transmitter are discussed, as well as receiver design issues.Optical preamplifier designs for IR-LAN applications

Abstract:
This paper examines some of the issues involved in the design of optical receivers for IR-LAN applications. Bootstrapped transimpedance preamplifiers and photoreceiver arrays are investigated as techniques for mitigating the effects of the large capacitances associated with the photodetector. In addition, the performance of a low cost, absorptive optical filter is analyzed and shown to have minimal angular dependence and low losses in the passband.Systematic study into resonant cavity light-emitting diodes
