摘要
A nonlinear optical loop mirror device having a distributed directional asymmetry. A dispersion decreasing optical fiber is formed into a loop by an optical coupler which divides input pulses into two component pulses that propagate around the loop in opposite directions, and which transmits and/or reflects returning component pulses in accordance with their relative phases. The parameters of the loop, such as its length, effective area, rate of change of dispersion, etc. are selected so that input pulses may be switched or transmitted in accordance with whether their widths or amplitudes are above or below predetermined threshold values.
