The use of optical devices for high-speed data transmission has been considered for some
time. Structures which can be used in optical integrated circuits are very important. Photonic …

In this work, the process of designing and simulating optical sensors based on photonic
crystal (PC) micro-ring resonators (MRRs) has been investigated. According to the PC type …

This work proposes a photonic crystal refractive-index sensor for detecting volatile organic
compounds (VOC). Two sensor designs are analyzed with Y-splitter photonic crystal …

In this study, merging two photonic crystal-based structures, a new design for an all-optical 2-

Optical microcavities have the ability to confine photons in small mode volumes for long
periods of time, greatly enhancing light-matter interactions, and have become one of the …

We present the design, fabrication, and the characterization of a high-quality-factor (Q) and
high-sensitivity photonic crystal (PhC) cavity sensor on the silicon-on-insulator platform. By …

This comprehensive review investigates the diverse landscape of blood component
detection through the one-dimensional, two-dimensional, and photonic crystal fiber …
