　　An athermal design for Solc-type filter based on periodically poled KTP (PPKTP) is proposed.The Athermal Static Phase Retardation (ASPR) direction in KTP,along which the quasi-phase-matched (QPM) condition is insensitive to the temperature,is found.The optimal design for Solc-type filter along ASPR direction is obtained.The coupling theory of QPM linear electro-optic effect is employed to study the polarization coupling in PPKTP.The study results demonstrate that the central passing wavelength of Solc-type filter keep unchanged with an almost 100 ％ 0utput when the temperature varies from 268 K t0 328 K.
