Nonmagnetic optical isolation and circulation with meta-surfaces and integrated photonics
Abstract/Contents
- Abstract
- Nonreciprocal optical components, such as optical isolators and circulators, allow light to transmit in one direction but block its transmission in the opposite direction. Such devices play an indispensable role in photonic systems, as they provide lasers with feedback protection and mitigate multi-path interference in communication channels. Constructing nonreciprocal devices require the breaking of Lorentz reciprocity, which has traditionally been achieved with magneto-optical materials. This method, however, is incompatible with integrated photonics platforms, most notably silicon photonics, because most standard optoelectronic materials do not exhibit magneto-optical effects. As such, there has been a significant demand for achieving optical isolation without magneto-optic materials. In this Thesis, we present our recent advancements in using nonmagnetic approaches for constructing nonreciprocal optical devices. First, we discuss the use of nonlinear optics for optical isolation and highlight some of their fundamental limitations. Next, we focus on the use of dynamic modulation of refractive index to achieve nonreciprocal manipulation of light. In particular, we discuss our recent developments in the simulation of dynamically modulated optical devices, as well as the design and demonstration of optical isolators and circulators on both meta-surface and integrated photonics platforms. These elements provide the basis for robust photonic systems, improve the flexibility in optical designs, and expand the degrees of control over light propagation.
