Waveguide-enhanced THz parametric generation and oscillation in thin lithium niobate wafers

[[abstract]]We observed 2-time efficiency increase in THz parametric generation when reducing the thickness of a lithium-niobate waveguide from 1 to 0.5 mm. Efficient THz emitted from such a waveguide OPO with an intracavity grazing-incidence grating[[fileno]]2030114030017[[department]]電機工程學
