The tunneling channel properties of 1D photonic quantum well with single barrier in the form (AB)m(CD)n(BA)m are studied with transmission matrix method(TMM).The results show that the number of tunneling channel only depends on the periodicity number of the well layer.Periodicity number of the barrier layer can not adjust the position, number,distance of tunneling channel.Larger lattice constant can significantly adjust the position, distance of tunneling channel, and the smaller the lattice constant is,the finer the tunneling channel becomes.The changes of incidence angle can slightly adjust the position,distance of tunneling channel, and the greater the incidence angle is,the finer the tunneling channel becomes.The abovementioned characteristics can provide guidance for designing new high quality quantum optical devices such as the adjustable multichannel optical filter.
