“…applications include arrayed waveguide gratings (AWGs) [211][212][213][214], echelle gratings (EGs) [215], cascaded MZIs [216], microring resonators (MRRs) [163,217,218], and Bragg grating filters such as contradirectional couplers [176,219]. AWGs, EGs, and cascaded MZIs are classified as finite impulse response (FIR) filters, which split input light to dispersive paths and recombine them at different outputs with regard to wavelength.…”

“…For the tunability, microheaters are commonly used to change the effective index of silicon waveguides, by which the transmission spectrum of MRRs can be efficiently tuned. In the study by Bélanger-de Villers et al [218], a thermally tunable filter in cascaded MRRs with (Figure 18). The device consists of three serially cascaded rings with radii of 2.5 µm and waveguide widths of 450 nm.…”

The tremendous growth of data traffic has spurred a rapid evolution of optical communications for a higher data transmission capacity. Next-generation fiber-optic communication systems will require dramatically increased complexity that cannot be obtained using discrete components. In this context, silicon photonics is quickly maturing. Capable of manipulating electrons and photons on the same platform, this disruptive technology promises to cram more complexity on a single chip, leading to orders-of-magnitude reduction of integrated photonic systems in size, energy, and cost. This paper provides a system perspective and reviews recent progress in silicon photonics probing all dimensions of light to scale the capacity of fiber-optic networks toward terabits-per-second per optical interface and petabits-per-second per transmission link. Firstly, we overview fundamentals and the evolving trends of silicon photonic fabrication process. Then, we focus on recent progress in silicon coherent optical transceivers. Further scaling the system capacity requires multiplexing techniques in all the dimensions of light: wavelength, polarization, and space, for which we have seen impressive demonstrations of on-chip functionalities such as polarization diversity circuits and wavelength- and space-division multiplexers. Despite these advances, large-scale silicon photonic integrated circuits incorporating a variety of active and passive functionalities still face considerable challenges, many of which will eventually be addressed as the technology continues evolving with the entire ecosystem at a fast pace.
