✦ Synopsis

We report on a theoretical analysis for the narrowband multiple wavelengths filter in aperiodic optical superlattice (AOS). The sequences of the opposite domains in AOS are optimized to realize the prescribed multiple wavelengths filtering using simulated annealing (SA) algorithm. Two, three and four wavelengths narrowband filters at telecommunication wavelength (near 1550 nm) are presented. The full width at half maximum (FWHM) of the filtering spectrum is about 0.5 nm. The influences of domain errors, as well as the working temperature, on the performance of the filters are also studied.
