Multichannel filtering properties of a one dimensional photonic crystal containing semiconductor photonic quantum well defect were theoretically investigated in the infrared region. We have considered two possible structures of photonic quantum well, symmetric ((AB)P(C1C2)Q(BA)P) and asymmetric ((AB)P(C1C2)Q(AB)P). It was found that, for a symmetric structure number of channels equal to Q + 1 whereas for asymmetric structure channel number is Q. Further it was observed that the position of channels can be tuned by means of temperature variations in semiconductor material. In addition, more channels can be generated by the use of a double photonic quantum well defect.
