This article represents a new Y-branch hybrid design of 2D photonic crystal with defect control. The structure is made of hexagonal arrays of InP nano-rods surrounded by air. This system is comprised of a modified add/change to a polymethylmethacrylate (PMMA) rod, which can be applied to the beam splitter selection device. The optical properties and radial of PMMA defect rods have been transfigured. By selecting an appropriate temperature, a change of refractive index and expanded radius are occurred. The obtained results have shown that the selected optical amplitude in a hybrid semiconductor-polymer Y-branch can be separated to 50–50, 60–40 and 67–33 % at wavelength 1.557 µm. Both of the photonic band gap and transmission spectra are calculated by using 2D finite different time domain (FDTD) method via OptiFDTD software. Such a device can be useful for photonic crystal switching devices in the integrated optical circuit. 相似文献
