摘要:
采用模压成型的塑料相位光栅作为波分复用/解复用器的分光元件,根据矩形相位光栅衍射公式,理论分析和仿真其衍射效率和信道分离情况.研究结果表明:对于一定刻槽深度的塑料相位光栅,+1级衍射效率和入射角的关系与理论分析结果一致,即对于采用的波长分别为575,625,675nm的入射光,当刻槽深度为200nm时,+1级衍射效率最大值所对应的入射角为25°左右,此时衍射效率理论值最大可达0.79; 信道间隔为50nm时,从探测器观察其光斑间隔为230μm左右,大于光纤直径(200μm),能有效实现光波分离,可应用于塑料光纤波分复用系统.
Abstract:
Using a plastic molding phase grating as a light splitting element for wavelength division multiplexer/de-multiplexer,theoretical analysis and simulation of the diffraction efficiency and channel separation according to the rectangular phase grating diffraction formula have been given in this paper.The results show that a relationship between order +1 of diffraction efficiency and beam incident angle is consistent with the theoretical analysis for a certain groove depth of the plastic phase grating.Specifically,diffraction order of m=+1 efficiency of up to 0.79 corresponding to the angle of indence of about 25° when using the wavelength of incident light,respectively 575,625,675 nm,and groove depth of 200 nm.If the channel interval is 50 nm,the spot interval of 230 μm on the detector surface is greater than fiber diameter(200 μm),so the wavelength division multiplexer/demultiplexer based on plastic grating is valid and feasible in actual application.
