Their broad frequency bandwidth capabilities, high isolation on/off ratio and low crosstalk in the input and output distribution lines readily lead to the construction of large dimension matrix switches. This thesis presents the design and analysis of a 2 x 4 broadband optoelectronic matrix switch operating at a wavelength of 1.55 µm . The switch is constructed utilizing InGaAs/InP avalanche photodiodes and an InGaAsP laser source modulated with several signals to test the performance of the switch over a wide range of frequencies. The switch is analyzed using conventional mathematical techniques for loss , SNR and frequency response and a system model is developed to characterize the overall performance. The results are then compared to actual measured data and summarized.130 pagesAvailable to the World Wide WebThe design and analysis of an optoelectronic broadband matrix switchThesis
