摘要
The photonic band structures of waves in configuration-periodic equilateral polygonal networks (EPNs) are studied in the paper. The results indicate that comb-like optical transmission spectrum can be realized by EPNs.The number, width, and range of continuous equidistant frequency bands can be controlled conveniently by adjusting the waveguide length and the unit cell numbers of upper arm. Those comb-like frequency bands have potential in the design optical narrowband filters, multichannel filters, and optical switching.
