Abstract: (1375 Views)
We propose a new model for fiber Bragg grating filter based on one-dimensional defective photonic bandgap (PBG) structures, which operates within the Telecom windows. The device is realized in an asymmetric photonic crystal microcavity with the defect layer placed in the center of the structure. It is shown that depending on the gate voltage value and as a result of tunneling parameter, the adsorption and dispersion properties change with the effective voltage change. By optimizing the effective parameters, optical filtering with telecommunication spectral bandwidth is possible. Also, tuning the filtering wavelength and the number of guided modes is performed by changing the properties of PC’s defect layer. The effect of the incident angle of the probe field on the transmittance spectra is calculated.
Keywords: photonic crystal microcavity, quantum-dot molecules, defect layer, tunneling, absorbtion &dispersion
