The successful marriage between nanophotonics and micro-electromechanics has led to the blossoming research field of optomechanics, with important outlooks both in the classical and in the quantum regimes. Indeed, optical sensors, modulators, and devices for quantum state manipulation are among the various applications demonstrated in recent years.

Optomechanical resonators exist in several geometries, based on microdisks, photonic crystal nanobeams, membranes etc., each with its own advantages and disadvantages. In this study, S. K. Manjeshwar et al. propose a hybrid geometry where a photonic crystal resonance (also known as guided mode resonance) hybridizes with a distributed Bragg reflector (DBR) through a Fabry-Pérot-like mechanism. As a result, the observable optomechanically-induced resonance frequency shift has a peculiar lineshape, not usually seen in other systems. Moreover, the proposed device could in the future embed in the DBR layers an active medium, enabling laser optomechanics in a compact platform. The article is a pleasant yet technically complete read, featuring advanced theoretical analysis and detailed experimental data.
