Estudo de luz espalhada em moléculas fotônicas baseadas em três cavidades acopladas

Abstract

In recent years, research on optical sensors based on integrated microcavities has advanced significantly, offering solutions for various technological demands, but most of them rely on spectral scanning, which requires complex experimental setups. This work proposes the study and design of a compact Photonic Molecule (PM) capable of exhibiting a consistent spectral response for the generation of scattered light when pumped at wavelengths coinciding with the resonances of its constituent cavities. Through simulations, it was demonstrated that the distribution of scattered light among the cavities varies characteristically with the pump wavelength, enabling the identification of the pump position relative to the resonances without the need for spectral scanning, by analyzing the spatial intensity patterns. This result may enable new sensing approaches based on scattered light for portable applications, without requiring complex experimental setups.
