利用具有特殊价值函数的模拟退火法设计了非周期光子量子阱(APQW)结构，实现了在任意预定频率下的多通道滤波。APQW结构由两个有限长的原型光子晶体(PC)夹在非周期性堆叠的介质层组成。插入APQW可以产生具有预定频率的指定缺陷状态。数值模拟结果表明，所设计的APQW能够达到预期的性能指标。
Designs of aperiodic photonic quantum-well (APQW) structures to achieve multiple channeled filtering at arbitrary preassigned frequencies are done by using the simulated annealing algorithm with a special merit function. The APQW structure consists of aperiodically stacked dielectric-layers sandwiched by two finite-length prototype photonic crystals (PCs). The insert of the APQWs can generate the specified defect states with predetermined frequencies. Numerical simulations show that the designed APQWs can achieve the desired specification.
