Abstract
Official abstract text for this publication.
A terahertz-wave element includes a waveguide ( 2, 4, 5 ) that includes an electro-optic crystal and allows light to propagate therethrough, and a coupling member ( 7 ) that causes a terahertz wave to enter the waveguide ( 2, 4, 5 ). The propagation state of the light propagating through the waveguide ( 2, 4, 5 ) changes as the terahertz wave enters the waveguide ( 2, 4, 5 ) via the coupling member ( 7 ).
First claim
Opening claim text (preview).
The invention claimed is: 1. A terahertz-wave detecting device comprising: a first waveguide that includes a nonlinear optic crystal and allows light to propagate therethrough; a second waveguide that allows light to propagate therethrough; a coupling member that causes a terahertz wave to enter the first waveguide; and a light detector configured to detect the light propagating through the first waveguide and the light propagating through the second waveguide, wherein the…
