Paper Abstract

A simple structure is proposed to generate slow and fast light simultaneously in a double-waveguide coupled disk resonator (DCDR) launched with dual contra-propagating inputs. The interaction between the intra-cavity backscattering and the losses out of cavity are investigated for the disk resonator while random surface defects (backscatters) are intentionally introduced in the cavity to produce the backscattering. The theoretical investigation done in this work shows that by adjusting the amplitude and/or phase difference between the dual inputs the interaction between the cavity modes and backscatters can be controlled thus the transmission and dispersion of the output lights of the system can be manipulated. This scheme is attractive for slow and fast light tuning applications especially when active tuning elements such as a p-i-n diode or a heater is absent in the cavity.
