Island photonic structures: Properties and application in sensing and metrology

Abstract

In this work, we consider a novel photonic crystal type, island resonator, as a perspective objects of the all-optical processing domain, which can be used in the logic gate and adder architecture. Another kind of novel structure, a gas-containing pneumatic photonic crystal, was considered as an optical indicator of pressure uniting several pressure scales of magnitude. This type of device includes a layered elastic platform, optical fibers, and switching valves, all enclosed in a chamber. We have investigated the distribution of deformation and pressure inside a pneumatic photonic crystal, its bandgap structure, and light reflection changes depending on the influence of external pressure and temperature. A method has been proposed to determine the fundamental molar gas constant R with the relative standard uncertainty near 10⁻¹⁰ that is based on extra-accurate volume controlling and highly sensitive pressure measurements in the framework of the scale echeloning procedure.
