Abstract: (2034 Views)
New defective resonant photonic crystals with optical response in infrared frequency range is proposed. This crystals is composed of periodic layers of slabs containing InAs quantum dots (QDs) and GaAs as barriers. Transfer matrix approach is utilized for investigation of the optical features of the proposed structures and in order to increase the simulation accuracy, despite of the previous studies, the effect of the disorders caused by fluctuations of the sizes of the layers/QDs are considered. Results show that disrupting the structural order of the crystal causes a defect mode generation in the band gap of the reflection spectrum. Due to the possible potentials of the defective structures in photonic devices such as optical filters/switches, tunability of its optical response is also investigated with taking into consideration of the crystal temperature, light incident angle and using an external control wave.
