摘要

A near-infrared (NIR) multichannel filter based on the use of a finite 1-D semiconductor metamaterial (MTM) photonic crystal (PC) is proposed. We consider a PC air/(AB)N/air, where N is the stack number, A is a dielectric layer, and B is a semiconductor MTM made of Al-doped ZnO (AZO) and ZnO. Resonant transmission peaks can be found in the frequency region where the permittivity of AZO/ZnO is negative. It is found that the channel number is equal to N-1 for a given N and that resonant channels are located in a passband of the photonic band structure. Additionally, the channel positions are tunable, i.e., they can be tuned by the thicknesses of A and B, the filling factor of AZO, and the incidence angle as well. The design of NIR tunable multichannel filter is of technical use for semiconductor optoelectronics.
