On the edge of the bandgap in a fiber Bragg grating(FBG) narrow peaks of high transmission exist at frequencies where light interferes constructively in the forward direction.
Comment on “Nonreciprocal Light Propagation in a Silicon Photonic Circuit”
Nonreciprocal Light Propagation Silicon Photonic Circuit
2015/8/7
We show that the structure demonstrated by Feng et al. (Reports, 5 August 2011, p. 729)cannot enable optical isolation because it possesses a symmetric scattering matrix. Moreover,one cannot construct...
