Numerical Investigation of Nanoresonator Based Ultra Narrow-Band Photonic Filters

A novel photonic crystal nanoresonator-based optical bandpass filter is designed with ultra narrow bandwidth, high quality factor, low optical loss and very small compact size. The proposed S-Shaped nanostructure is playing a very significant role on narrow wavelength filtering and effectively localize the incident light signal which leads to the high-quality factor is obtained with 100% transmission. The different light coupling mechanism is used to realize the four dissimilar narrow bandpass filters. These nano-filter performance parameters are numerically investigated by Finite Difference Time Domain Method (FDTD). The nanoresonator coupled waveguides platform is designed with high quality factor as about 3873.70, ultra narrow bandwidth of 60 GHz and 0.13 THz. The presented photonics platform footprint is very compact as about 128.52 μm ² . These enhanced results highly suitable for optical integrated circuits, 5G and 6G optical wireless network.
