在1.5μm波长下,证实了9信道单模光栅波分复用法。装置的插入损耗低至1.5dB。芯-芯间隙为36μm的光纤阵列可作信道集成器用,产生的信道间隔为20(?)、信道宽度为2(?)。
At 1.5μm wavelength, 9-channel single-mode grating WDM method was verified. The insertion loss of the device is as low as 1.5dB. A fiber array with a core-to-core gap of 36 μm can be used as a channel integrator, resulting in a channel spacing of 20 (?) And a channel width of 2 (?).
