Performance of Micro-ring Wavelength Division Multiplexing
Here, we numerically show the use of time and wavelength division multiplexing (WDM) to solve four independent tasks at the same time in a single photonic chip, serving as a proof of concept for our proposal. The flat-top channel response obtained by the second-order filter design is exploited to compensate for the detrimental. Photonics offers the flexibility of multiplexing streams of data not only spatially and in time, but also in frequency or, equivalently, in wavelength, which makes it highly suitable for parallel computing. However, the resonant wavelength of Si-MRRs is very sensitive to temperature fluctuations and fabrication process. We demonstrate a fully integrated eight-channel dense wavelength-division multiplexing silicon photonic transceiver supporting 200-Gbps per-channel PAM4 operation, enabling a total chip-to-chip data rate of 1. The transmitter employs compact single-bus microring modulators, whereas the.
