Ultra-Narrow-Band Filter Based on High Q Factor in Metallic Nanoslit Arrays

Ultra-Narrow-Band Filter Based on High Q Factor in Metallic Nanoslit Arrays

Here we propose a novel high <i>Q</i> ultra-narrow-band filter in the optical regime. Multiple high <i>Q</i> resonances are achieved in ultra-thin metallic nanoslit arrays on stacked low index–high index dielectric (LID–HID) substrate. Based on the cooperative effect of suppr...
