“…Several applications of photonic crystal resonators: perfect reflectors in waveguides [13,14], lensing and bridgelike regulators [15,16], signal processing [17,18]. an optically linear PhCr provides an opportunity to control the beam entrance angle into the resonator due to the phenomenon of shifting bands discussed in [19]. It was shown there that the Kerr nonlinear coating layer leads to the so-called quasi-shift effect of bands inside the total internal reflection (TIR) region, causing a strong deviation in transmission and reflection of the light signal introduced into the structure through the input.…”

“…The all-optical logic gates design based on the nonlinear elements was proposed in [17] and a partial case for the optical logic AND gate architecture was discussed in [18]. An important effect of shifting bands caused by the introduced inside PhCr χ (3) -type nonlinearity was found in [19] and general features of all-optical signal processing was discussed.…”

In this work, we consider a novel photonic crystal type, island resonator, perspective objects of all-optical processing domain, which can be used in the logic gate and adder architecture. Another kind of novel structures, gas-containing pneumatic photonic crystal, was considered as an optical indicator of pressure uniting several pressure scales of magnitude. This type of device includes layered elastic platform, optical fibers and switching valves, all enclosed into a chamber. We have investigated theoretically 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 high sensitive pressure measurements in the framework of scale echeloning procedure.
