Abstract
Free Space Optical (FSO) interconnects can resolve several existing problems in current copper-based chip-to-chip and board-to-board communications, including electromagnetic interference and limited data capacity. FSO systems can overcome these limitations by employing Multiple Input Multiple Output (MIMO) schemes which increase the number of parallel datastreams. However, due to the increase in the number of transmitters and receivers, MIMO FSO systems are prone to optical crosstalk due to misalignment of components and divergence of optical transmitters. Space time coding (STC) is a technique that can potentially mitigate the problems caused by optical crosstalk in FSO systems. However, hardware suitable for implementation of STC on MIMO FSO systems has yet to be realized. This thesis describes the design and testing of a MIMO transceiver system suitable for implementing STC. The designed system includes a 4 4 transmitter board, two designs for the receiver board and the optical elements required for such communication. A prototype Single Input Single Output (SISO) link is constructed to characterize the system by performing several tests, including data rate tests, range tests, power tests and noise analysis. A Multiple Input Single Output (MISO) system is also characterized to provide experimental inputs in a simulation which demonstrates the practical e ffectiveness of STC in FSO systems.
