Abstract
The present invention includes a slanted periodically poled deviceincluding a light input surfaceand a light output surfaceparallel to each other and a terahertz wave input surfaceorthogonal to the light input surfaceand the light output surface, a pump beam sourcewhich emits pump beamperpendicularly to the light input surface, and a photodetectorwhich detects an up-conversion signal beam A converted from a terahertz waveemitted perpendicularly from the light output surface. The slanted periodically poled deviceis configured to generate the up-conversion signal beam A in the same direction as and in parallel with the pump beamby quasi phase matching between the terahertz waveperpendicularly incident from the terahertz wave input surfaceand the pump beam
