We demonstrate an electro-optic ˇSolc-type wavelength filter in periodically poled lithium niobate (PPLN). ˇSolc-type transmission spectrum is observed experimentally in a PPLN with four periods from 20.2 μm to 20.8 μm. Modulation of transmission power of the filter can be realized by applying electric fields along Y -axis of PPLN. It is observed that the wavelength can also be tuned
by temperature. Furthermore, we report on a theoretical analysis for the narrowband multiplewavelength filter in aperiodic optical superlattice (AOS). The sequences of the opposite domains in AOS are optimized to realize the prescribed multiple-wavelength filtering by using a simulatedannealing
(SA) algorithm. The influences of domain errors, as well as the working temperature, on the performance of the filters are also studied.
