Lithium niobate waveguide

WebThe photorefractive effect induced by 775-nm laser light on doped lithium niobate crystals is investigated by the direct observation in the far field of the transmitted-beam distortion as a function of time. Measurements performed at various Zr-doping concentrations and different light intensities show that the 775-nm light beam induces a steady-state … WebA silicon nitride (SiN) and lithium niobate heterogenous integration platform on SiN waveguide circuits is introduced. An efficient evanescent coupling structure is realized for low‐loss light transitions between waveguides of different materials with a measured mode transition loss of 0.4 dB. An electro‐optic Mach–Zender modulator on SiN is built with …
