title: Aperiodic photonic quantum-well structures for multiple channeled filtering at arbitrary preassigned frequencies.
abstract: 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.
