Wide-angle all-optical filtering via defective distributed Bragg reflectors

Abstract In this paper, we propose a distributed Bragg reflector (DBR) involving active atoms doped in the defect layer to manipulate the transmission and group velocity of a weak probe field. We exploit three-level rubidium atoms in a Ladder configuration, which provides the possibility of controll...
