High Transmission Bit Rate of A thermal Arrayed Waveguide Grating (AWG) Module in Passive Optical Networks
摘要：
本文对无源光网络（PON）中硅基热阵列波导光栅（AWG）的高传输速率进行了参数化分析和研究，该阵列波导光栅由LiNbO 3/PMMA混合材料构成，在较宽的影响参数范围内实现高传输速率。从理论上研究了阵列波导光栅（AWG）波长漂移随温度的变化与材料折射率和波导尺寸的关系。通过选择合适的器件材料和结构参数，可以实现AWG的热化。此外，我们分析了热AWG在基于最大时分复用（MTDM）技术的无源光网络（PON）中的数据传输比特率。
英文摘要：
In the present paper, high transmission bit rate of a thermal arrayed waveguide grating (AWG) which is composed of lithium niobate (LiNbO3)/polymethyl metha acrylate (PMMA) hybrid materials on a silicon substrate in Passive Optical Networks (PONs) has parametrically analyzed and investigated over wide range of the affecting parameters. We have theoretically investigated the temperature dependent wavelength shift of the arrayed waveguide grating (AWG) depends on the refractive-indices of the materials and the size of the waveguide. A thermalization of the AWG can be realized by selecting proper values of the material and structural parameters of the device. Moreover, we have analyzed the data transmission bit rate of a thermal AWG in passsive optical networks (PONs) based on Maximum Time Division Multiplexing (MTDM) technique.
