提出并演示了一种低串扰平顶4通道粗波分复用（解）复用器。级联马赫-曾德干涉仪用于提供平坦的通带。通过利用基于弯曲定向耦合器的功率分配器，马赫-曾德尔干涉仪的串扰对于所有四个通道来说都可以是超低的。所制造器件的测量结果表明串扰为
A low-crosstalk and flat-top 4-channel coarse wavelength-division multiplexing (de) multiplexer is proposed and demonstrated. The cascaded Mach-Zehnder interferometers are used to provide flat pass-bands. By utilizing the power splitters based on the bent directional couplers, the crosstalk of the Mach-Zehnder interferometers could be ultra-low for all four channels. The measurement results of the fabricated device show that the crosstalk is
