Highly efficient 1×3 power splitter at 1550 nm for triple play applications using photonic crystal waveguides

Abstract

We presented a highly efficient 1 × 3 optical power splitter based on photonic crystal waveguides (PCWs) with a triangular lattice of air holes. By only modifying a single hole in a Y junction area, the input power can be almost evenly split into three ports. The optimal device can operate with a total transmittance higher than 99% simultaneously at 1384, 1490, and 1550 nm, which are within the E-, S-, and C-bands of optical communication spectra, respectively. It provides a new method and a compact model to split the input power into three channels in PCW devices and can find triple play applications in an optical communication system. © 2014
