AI Article Synopsis
- - When single microdisks with active emitters are used, they naturally cause simple backscattering and lack effective control over this process.
- - By adjusting the cavity size, researchers can manage the direction of backscattering in microdisks, confirmed through experiments with two coupled microdisks.
- - The study also identifies diabolical points at the resonance of the two microdisks, aligning with theoretical predictions, which could advance quantum information processing in photonic networks.
Article Abstract
In single microdisks, embedded active emitters intrinsically affect the cavity modes of the microdisks, resulting in trivial symmetric backscattering and low controllability. Here we demonstrate macroscopic control of the backscattering direction by optimizing the cavity size. The signature of the positive and negative backscattering directions in each single microdisk is confirmed with two strongly coupled microdisks. Furthermore, diabolical points are achieved at the resonance of the two microdisks, which agrees well with theoretical calculations considering the backscattering directions. Diabolical points in active optical structures pave the way for an implementation of quantum information processing with geometric phase in quantum photonic networks.
