摘要：

A compact integrated folded Solc filter using periodic 90degrees-domain structures in KNbO3 single crystals is proposed. The periodic 90degrees-domain structures with a period of 200 pm are fabricated on 0.7-mm-thick ((1) over bar 01)-cut KNbO3 single-crystal plates by applying an electric field of 200 V/mm. Using the refractive index change between 90degrees-domains, we can construct the same arrangement for a folded Solc filter. The measured filtering properties agree well with the calculated ones. This is the first demonstration of an optical filter using periodic domain structures other than 180degrees-domain structures. It is now possible to fabricate a compact folded Solc filter without inconvenient alignment.
