Abstract

The design and experimental characterization of the substrate-mode guided wave optical backplane using 0.5mm, 0.75mm and 1mm pitch 2D optical beam array are described. The system sues arrays of multiplexed holograms to implement board to board interconnects and employs 250micrometers pitch 2D vertical-cavity surface-emitting lasers and microlens array as transmitter to provide 0.5mm to 1mm pitch 2D beam array, operating at 850nm. By comparing the optical beam properties at the detector plane including the spot size and power uniformity of optical beam array, as well as signal to noise ratio, the acceptable design parameters are justified. Furthermore, the improvement of throughput that can be achieved by 1D and 2D crosstalk analysis within the same design concept is presented. The results of crosstalk analysis obtained here are used for application to the standard five-board holographic optical backplane system.
