Strong-confinement silicon photonics: from telecom-grade signal processing to light-powered nanomachines

Milos Popovic

University of Colorado at Boulder


Abstract: Microphotonic circuits based on strong confinement raise the prospect of dense photonic integration on a chip, highly energy efficient on-chip communication links, and of novel device concepts based on unique device physics and topologies that become practical in this regime, including optical nonlinear effects and optical forces. In this talk, I will describe the demonstration of telecom-grade filters and hitless wavelength switches in strong-confinement microphotonics. I will also talk about device concepts based on localized destructive mode interference and a new, unidirectional guided Bloch wave, that enable efficient waveguide crossings, modulators, and other optically efficient contacted structures. I will describe recent efforts to integrate silicon photonics with advanced CMOS electronics in the front end CMOS process, and will show the first demonstrations of photonic devices in 65nm and 32nm CMOS technology with no process changes, compatible with microprocessor grade state-of-the-art CMOS. These developments are the first results of current research on deeply integrated photonics in both processor and DRAM technology.
