non-Hermitian topological interconnected light circuits

quantum inspirations

Inspired by the classic quantum mechanics and the electric trasmission line, a network of wave-guiding media can present optical properties qualitively and quantatively different from their components.

An optical switch composed of a network of waveguide.

The studies have two branches, namely the non-Hermitian or parity-time symmetric (\(\mathcal{PT}\)-symmetric) (Li et al., 2020; Zhi et al., 2018; Wu, 2019; Wu† et al., 2019; Wu & Yang, 2017) and the classical dielectric (Wu & Yang*, 2019). They are both good candidates in the project novel integrated photonic nanodevices, chips, & circuits.
