Abstract
A TE-TM mode converter is provided which is capable of performing a TE-TM conversion in a wide bandwidth. In a TE-TM mode converter using an electrooptic effect, a waveguide is formed on a substrate using lithium tantalate having a birefringence of about 0.0005 or less. The direction of an optical axis of lithium tantalate forming the waveguide is approximately parallel to a primary surface of the substrate. In addition, a first electrode and a second electrode are provided on the primary surface of the substrate so as to face each other with the waveguide placed therebetween.
