摘要：

A wavelength division multiplexer (WDM) based on asymmetric grating-assisted couplers is proposed, which can flexibly adjust the bandwidth by changing the corrugation width of the grating. The simulation results show that, compared with asymmetric uniform grating-assisted couplers, asymmetric unilateral amplitude apodization grating-assisted couplers and asymmetric bilateral amplitude apodization grating-assisted couplers can effectively suppress the sidelobes. The experimental results show that the insertion loss of each wavelength channel is between 0.23dB and 0.58dB, and the sidelobe suppress ratio of both unilateral amplitude apodization grating-assisted couplers and bilateral amplitude apodization grating-assisted couplers is larger than 10dB, which reduces channel crosstalk and proves the feasibility of the wavelength division multiplexers.
