摘要	An apparatus for use in optical communication systems to multiplex/demultiplex an optical signal consisting of an optical channel(s) of distinct wavelength(s) having a select channel spacing within a select wavelength range. The apparatus includes a plurality of optical waveguides aligned generally along the same optical axis with each having a propagating end. At least two of the optical waveguides each propagate a distinct multiplexed optical signal comprising a plurality of channels, with the multiplexed optical waveguides being arranged in a multiplexed linear array. The others of the optical waveguides are single channel waveguides arranged in a two dimensional array with linear rows perpendicular to the multiplex linear array and with each linear row corresponding to a multiplex optical waveguide. A reflective echelle grating is optically coupled to the plurality of optical waveguides along the optical axis and receives an optical signal emitted from at least one of the optical waveguides and detracts the optical signal(s) to at least one other of the optical waveguide(s).
其他摘要	一种用于光通信系统的装置，用于多路复用/多路分解由一个或多个不同波长的光信道组成的光信号，该光信道具有在选择波长范围内的选择信道间隔。该装置包括多个光波导，这些光波导通常沿同一光轴对准，每个光波导具有传播端。至少两个光波导各自传播包括多个信道的不同的多路复用光信号，多路复用光波导以多路复用线性阵列排列。光波导的其他部分是以二维阵列排列的单通道波导，其中线性行垂直于多路线性阵列，并且每个线性行对应于多路复用光波导。反射阶梯光栅沿光轴光学耦合到多个光波导，并接收从至少一个光波导发射的光信号，并将光信号减弱到光波导中的至少另一个（s）。）。
