摘要We report the fabrication of an optical fiber Bragg grating assisted mismatched coupler based on the fused biconical tapered technology. The investigation of the spectrum properties shows that the coupler has a good filtering property. The drop filtering efficiency as much as 94.2% at 1553.5nm is achieved. Furthermore, using the fabricated coupler, a wavelength de-multiplexing transmission experiment is carried out in a 10Gbps system with NRZ optical signals. Experimental results show that the coupler basically realizes the function of wavelength de-multiplexing.
