Investigation of Optical-Switching Mechanism Using Guided Mode Resonances

Recently, photonic crystals have paved the way to control signals. Therefore, this research numerically investigated design of optical switch using guided-mode resonances in operating a communication window around 1.55 ?m. The device is based on dielectric slab waveguide make it compatible with waveguides circuits. Moreover, two signals are used and termed as data signal signal. coupled into an out-of-the-plane vertical coupling mechanism, whereas index-guided amplify switching parameters adjusted by changing number crystal periods implementing varying radius PhC-cavity within middle PhC-lattice, where characteristics terms resonant wavelength, reflection peaks, linewidth, quality factor can be adjusted. numerical simulations carried out open-source finite difference time domain-based software. Congruently, 7% amplification achieved wavelength shift 0.011 ?m 12.64. utilized implement mechanism. easy has great potential programmable photonics integrated
