Abstract
In order to study the factors affecting the confined state in a photonic quantum well (PQW) structure, the transmission characteristics of the PQW structure with different dielectric thickness and constants were studied by means of optical transfer matrix,then it was known that the frequency in the PQW structure changed with the dielectric constants and thickness. The frequency in a confined state can be changed linearly by changing the dielectric thickness and constants in wells and barriers a little. The dependence of the confined frequency on the dielectric thickness and dielectric constants in wells is more than that in barriers. The investigation results might be used to obtain the desired frequency in the confined state in a PQW structure.
