测量了垂直耦合微环谐振腔(VCMRR)滤光片在1.55/splµ/m波长下的超短光脉冲传输特性，并对其每通道传输容量进行了估算。当来自光纤激光器的秒脉冲形状的1.2ps输入脉冲入射到半高全宽为0.75 nm(94 GHz)的微环谐振腔滤光片上时，测得输出脉冲宽度为3.4ps。从理论上分析了滤光片的脉冲展宽，证实了从滤光片光谱响应带宽估算的脉冲展宽与测量结果吻合较好。
The ultrashort optical pulse transmission characteristics of a vertically coupled microring resonator (VCMRR) filter were measured at 1.55 /spl mu/m wavelength, and the transmission capacity per channel was evaluated. The pulsewidth at the output was measured to be 3.4 ps, when 1.2 ps input pulse with a sech pulse shape from a fiber laser was incident on the microring resonator filter with a fullwidth at half-maximum (FWHM) of 0.75 nm (94 GHz). From this result, the maximum transmission capacity of the filter was estimated to be approximately 50 Gb/s. The pulse broadening through the filter was theoretically analyzed, and it was confirmed that the pulse broadening evaluated from the bandwidth of the filter spectrum response were in good agreement with the measured results.
