Abstract

In this paper, the proposed switch of T-type based on photonic crystal ring resonator has been studied. The proposed structure is composed of two waveguides, between them the photonic crystal ring resonator is placed. Our structure can switch two wavelengths together following an external effect. The proposed design has a simple geometric shape, therefore it is capable to realize optical switch applicable to photonic integrated circuits. The parameters that can characterized the performance of optical device are quality factor, crosswalk and foot print. The values of crosstalk, quality factor and footprint that have been obtained are – 41.5db, 330 and 89.38 μm², respectively, which are superior to earlier reported values. The finite different time domain (FDTD) and plane wave extended (PWE) methods are used to calculate the outputs spectrum and band gap, respectively.
