摘要

In this paper, we investigate the optical transmission properties of two-dimentional (2D) defective two-segment-connected triangular optical waveguide networks (DTSCTOWNs). By means of the network equation and generalized eigenfunction method (GEM) we calculate the optical transmission spectra of 2D DTSCTOWNs and find many groups of extreme narrow photonic bands (ENPBs), whose number and frequencies are mainly determined by defect types and the number of defect waveguides. The relevant quantitative rules of ENPBs are obtained and this kind of ENPBs will possess applications for the designing of extreme-narrowband filters, high-sensitive optical switches, and other all-optical equipment. In order to analyze the futures of ENPBs, based on the decomposition-decimation method of electronic energy spectra we propose an interesting pseudo dynamic method (PDM). Comparing with GEM, for the same kinds of 2D DTSCTOWNs PDM can not only reduce the computations of ENPBs significantly, but also predict the splitting types of ENPBs directly. Additionally, it is also found that injecting EM waves with the frequencies of ENPBs in 2D DTSCTOWNs strong photonic localizations can be produced at the nodes connecting with defect waveguides. It may be useful for the designing of high-efficient photonic energy storage devices.
