TL;DR: In this paper, the authors demonstrate a low-power WDM transmitter near a 1550-nm wavelength using silicon microrings, which achieves low energy-per-bit values of 36 fJ/bit under 2.4

TL;DR: The same foundries and processes that were developed to build transistors are being repurposed to build chips that can generate, detect, modulate, and otherwise manipulate light as discussed by the authors.

TL;DR: The results suggest that gain peaking is a generally applicable tool for increasing detector bandwidth in practical photonics systems without requiring the difficult process of lowering detector capacitance.

TL;DR: This paper presents a 5 × 25 Gb/s carrier-depletion microring-based wavelength-division multiplexing (WDM) transmitter in 65 nm CMOS that incorporates 2-tap asymmetric pre-emphasis to effectively cancel the optical nonlinearity of the ring modulator.

TL;DR: Measurements of the nonlinear distortions of a traveling-wave silicon Mach-Zehnder modulator based on the carrier depletion effect suggest silicon may be a suitable platform for analog optical applications and show that the linearity of a silicon traveling wave Mach- Zehndermodulator can be improved by differentially driving it.
