Abstract
Silicon – based devices for optical signal processing has established itself as a mainstay in the field of photonics. Their special significance lies in their ability to be manufactured alongside CMOS electronics, thus enabling commercial applications in transceivers and interconnects. In this paper, we present recent research progress pertaining to ultrafast optical signal processing on silicon – based platforms. Advances in on – chip wavelength and mode division multiplexing strategies with the potential for meeting 200GHz dense wavelength division multiplexing standards across the C – and L – bands will be discussed. In addition, the development of a silicon – based nonlinear optics platform with high nonlinear figures of merit will be presented. Nonlinear optical devices fabricated on the aforementioned platform possess nonlinear parameters 500 times larger than that in silicon nitride waveguides, while possessing negligible nonlinear losses at 1.55µm
