    • There is provided a filter assembly for combining a wavelength multiplexed optical signal by multiplexing optical signals of different wavelength emitted from respective optical devices, and/or for dividing a wavelength multiplexed optical signal into optical signals of different wavelength and causing the optical signals of different wavelength to enter respective optical devices. This filter assembly comprises: a light transmitting member within which each optical signal propagates; plural optical filters disposed on an upper face of the light transmitting member at a predetermined spacing wherein each optical signal passes through the optical filters; upper reflective layers respectively provided between adjacent ones of the optical filters; and a lower reflective layer provided on a lower face of the light transmitting member, and wherein the wavelength multiplexed optical signal propagates along the same optical path within the light transmitting member.
    • 提供了一种滤波器组件,用于通过复用从各个光学器件发射的不同波长的光信号和/或用于将波长复用光信号分成不同波长的光信号并使不同波长的光信号 进入相应的光学装置。 该过滤器组件包括:光传输构件,每个光信号在其内传播; 多个滤光器,以预定间隔设置在所述光传输部件的上表面上,其中每个光信号通过所述滤光器; 分别设置在相邻的滤光器之间的上反射层; 以及设置在所述透光构件的下表面上的下反射层,并且其中所述波长复用光信号沿着所述光透射构件内的相同光路传播。
