A relay consisting of an f/1.5 95 mu m diameter microlens and an f/1 75 mu m microlens has been modelled to study how variations in alignment and manufacturing parameters affect the efficiency of the system. It was found that a 5% variation in focal

Within the past 15 years there has been significant progress in the development of two-dimensional arrays of optical and optoelectronic devices. This progress has, in turn, led to the construction of several free-space digital optical system demonstr

Two-dimensional arrays of logic self-electrooptic effect devices (L-SEEDs), consisting of electrically connected quantum-well p-i-n diode detectors and modulators are demonstrated. The topology of the electrical connections between the detectors is e

Free-space interconnection of widely spaced pixels may be implemented using microlenses, rather than conventional imaging. Advantages, problems, and studies of system capacity are discussed.

A prototype digital free-space photonic switching fabric consisting of three cascaded 16*8 arrays of symmetric self-electrooptic effect devices (S-SEEDs) is demonstrated. The three stages implement the input interface and one 2*1 node stage of a mult

One of the more promising interconnection schemes proposed for use in photonic switching networks is the crossover interconnection network; however, reported implementations of the crossover have been limited in size and complexity. A large-scale cas

Optical energy is limited in any optical interconnect system. Therefore we require an amplifier to decrease the optical energy for data communication. Electrical power consumed by this amplifier reduces the optical power required. An optical receiver
