Crosstalk analysis of synchronous and asynchronous optical chip interconnects with direct detection

Abstract

This thesis provides a crosstalk analysis of optical chip interconnects via single-mode waveguides with synchronous transmission and asynchronous transmission. This crosstalk model is general and can be used for any type of waveguide network. Three cases of laser sources will be considered: (1) each channel operates with an independent laser sources, (2) all laser sources have the same mean wavelength but with different phase noise processes, and (3) all laser sources are identical with the exception of the initial phases. The analysis takes into account the coupling-induced crosstalks between adjacent waveguides, the laser linewidth, the shot noise, the dark current generated by the photodiode, and the post-detection thermal noise. Bit error probabilities versus received peak powers are presented together with power penalties.
