Based on a silicon-on-insulator (Silicon-on-insulator, SOI) material system design and optimization of a high performance, the polarization independent of 1 × 3 subwavelength grating stars beam splitter.
Similarly,for the TM polarization,it can also get the back diffraction efficiency and the forward diffraction efficiency respectively: , (12) 2.2 Structure design This paper based on the single tooth grating as an example,design a 1 × 3 grating beam splitter.The device is based on the multi-layer dielectric film structure of SOI material system ,the grating is placed on the top silicon layer.
A bunch of plane monochromatic vertical irradiate on the structure,through the grating,incident TE and TM polarized light is divided equally between 0 and ± 1-order transmitted diffraction orders.Paper assume that grating in the y direction is infinite,dielectric material of the composition grating is lossless,and the dispersion of the material is also negligible, design and optimization the device by rigorous coupled-wave analysis method.
(a) TE polarized angle response lines (b) TE polarized angle response lines Figure 3 1.55μm at the angle of the device response spectrum 3 Conclusion Based on the SOI material system performance, the polarization-independent 1 × 3 subwavelength grating beam splitter, in the 1550nm wavelength range, at vertical incidence,the device can achieve power splitting for the TE and TM polarized light at the same time.The device is only need a layer of simple subwavelength grating,which makes it easy to integrate with other devices within a relatively wide band range.The grating beam splitter can be widely used in communication systems routing and switching devices. 4 Acknowledgement This work is supported by Natural Science Foundation of Jiangxi Province No.20122BAB201026 5 References [1].
