Abstract
Official abstract text for this publication.
The present invention includes a slanted periodically poled device 12 including a light input surface 12 a and a light output surface 12 b parallel to each other and a terahertz wave input surface 12 c orthogonal to the light input surface 12 a and the light output surface 12 b , a pump beam source 14 which emits pump beam 1 perpendicularly to the light input surface 12 a , and a photodetector 16 which detects an up-conversion signal beam A converted from a terahertz wave 3 emitted perpendicularly from the light output surface 12 b . The slanted periodically poled device 12 is configured to generate the up-conversion signal beam A in the same direction as and in parallel with the pump beam 1 by quasi phase matching between the terahertz wave 3 perpendicularly incident from the terahertz wave input surface 12 c and the pump beam 1.
