Abstract: PURPOSE: A multi/demultiplexer is provided to eliminate an additional device for regularizing a loss by regularizing a minimum loss of an output waveform using an offset. CONSTITUTION: The device is composed of a substrate(51), the first arrayed waveguide(52), the second arrayed waveguide(54), a slab(55), and an optical arrayed waveguide grating(53). The first arrayed waveguide and the second arrayed waveguide comprises a linear arrayed waveguide of an input side, a linear arrayed waveguide of an output side, and a curved arrayed waveguide of an output side respectively. An offset of specific value is provided to a connecting portion between the curved arrayed waveguide and the linear arrayed waveguide. If a signal light of a constant mode progresses along an optical waveguide, the intensity distribution in the curved arrayed waveguide and the intensity distribution in the linear arrayed waveguide are different. The disagreement of the intensity distribution causes the transfer loss of the signal light at the connecting portion between the curved arrayed waveguide and the linear arrayed waveguide. Since the offset of specific value is provided to the connecting portion between the curved arrayed waveguide and the linear arrayed waveguide, it is possible to minimize the transfer loss.
Abstract translation: 目的：提供多/多路分配器以消除用于通过使用偏移来规范输出波形的最小损失来规范损耗的附加装置。 构成：该器件由基片（51），第一阵列波导（52），第二阵列波导（54），平板（55）和光阵列波导光栅（53）组成。 第一阵列波导和第二阵列波导包括输入侧的线性阵列波导，输出侧的线性阵列波导和输出侧的弯曲阵列波导。 在弯曲阵列波导和线性阵列波导之间的连接部分提供具体值的偏移。 如果恒定模式的信号光沿着光波导进行，则弯曲阵列波导中的强度分布和线性阵列波导中的强度分布是不同的。 强度分布的不同意味着在弯曲阵列波导和线性阵列波导之间的连接部分处的信号光的传输损耗。 由于具体值的偏移被提供给弯曲阵列波导和线性阵列波导之间的连接部分，所以可以最小化传输损耗。
