Virtual reality (VR) technology has been applied successfully in a wide range of fields, as mobile devices and wearable electronics have become popular commercial products. In this pilot study, we apply the VR technology with seven main steps to reconstruct a historical site (i.e., a nonextant historic east Taiwan railway station) to develop a VR simulation system. It provides an interactive environment...
In this study, we investigate the potential of a light-focusing device (LFD) for high coupling of self-collimated beams from two-dimensional photonic crystals. The high transmission power is higher than 70% by removing at z=8. The LFD consists of a slab waveguide to calculate its coupling efficiency, and the numerical results show the coupling efficiency is about 66%. The proposed LFD increase the...
In this paper, we proposed a photonic crystal ring-resonator (PCRR) based on a quasiring shape. The numerical results show that the PCRR is feasible to design a high quality filter for accurate wavelength control.
