WebThe change in the absorption spectra due to reversal of the direction of light propagation (nonreciprocity of absorption) is a consequence of a simultaneous violation of both time-reversal and spatial-inversion symmetries. Here, we report on a Webmagneto-optical crystal based Faraday rotation [11, 12], reservoir engineering [13] and photonic Aharonov-Bohm e ect [14]. In addition to nonreciprocity, tunable slow and fast light propagation [15, 16] is another useful mechanism to provide on-demand photon transmission in chip devices.
