We present a novel concept for THz generation based on non-linear integrated waveguide optics leading to compact, coherent and room-temperature stable THz sources. Our concept is based on non-linear frequency down conversion of near infrared modes in a silicon waveguide with organic electro-optic polymer cladding. Organic electro-optic polymers have an engineered ultra-high non-linearity [1] and can...
Poled and unpoled chromophore-containing polymers offer some unique advantages in device functionality and fabrication. UV light and electron beam (e-beam) can bleach out the color of chromophores and reduce the index of refraction of the polymer. The photobleaching and e-beam bleaching methods form optical waveguides in a single step and do not involve solvents or wet chemicals, and can be applied...
