Abstract

In this paper, a high-speed 4 X 4 optoelectronic switch with on-chip optical signal distribution is presented. The switching matrix integrates both metal-semiconductor-metal photodetectors and polyimide waveguides onto a monolithic structure. The bias-switched photodetectors are used to select which incident optical signals are to be detected and converted to electrical signals for distribution. The polyimide waveguides provide on-wafer distribution of the input optical signals to the detectors. This switch had an isolation of less than 48 dB at 1.0 GHz, a crosstalk of greater than -26 dB at 0.8 GHz, and a bandwidth between 4.3 to 6.5 GHz depending on the particular crosspoint being measured. This optoelectronic switch shows improved performance over a wider bandwidth compared to the 3 X 3 optoelectronic switch presented earlier. The current switching implementation is also easier to package because it does not require the precise alignment to discrete fibers over the photodetectors for optical distribution. Fabrication details, circuit configuration, and performance for the 4 X 4 optoelectronic switch will be discussed in greater detail in these proceedings.
