多重散射理论对光子晶体量子阱结构光子共振透射的研究

The resonant transmission properties of a photonic quantum-well were studied by a spheric-wave expansion method in combination with multiple-scattering techniques.Similar to the electronic quantum wells the photonic quantum-well is constructed by sandwiching a uniform medium between two photonic barriers.The calculated resonant transmission peaks show that some photonic states exist in a quantized way,satisfying a quantized frequency relation.The finite photonic potential barrier plays different confining roles on the different photonic levels.By appropriately choosing the parameters of the well and barrier,a high-quality multichannel filtering can be achieved.The calculation in the coupled double photonic quantum-wells shows that the coupling between the modes in the two wells weakens with the widening of the barrier thickness,and the mode splitting becomes smaller.
