摘要

We propose a scheme in which an arbitrary incidence can be made perfectly reflected/transmitted with a phase mod-ulator.We analyze the variation of intracavity field as well as output field with closed-loop phase φ1 of the control fields and relative phase φ2 of the probe beams.With two phases,medium absorption and light interference can be controlled so that photon escape from the cavity can be manipulated,thus an intensity switching based on phase modulation can be real-ized.And the condition for perfect transmitter or reflector is obtained.Then based on the transmission/reflection analysis,the total absorption of this system can be investigated.Therefore our scheme can be used as an absorption interferome-ter to explore the optical absorption in some complicated system.The state delay of the output light intensity,which is dependent on φ1 or φ2,can be applied in the realization of quantum phase gate and subtle wave filter.And based on this scheme,we implement the state transfer between perfect transmitter/reflector and non-perfect coherent photon absorber via relative-phase modulation.
