lithium niobate thin film bonded to a 2-µm thick thermally grown silicon dioxide layer on a silicon substrate (NANOLN Inc.). To utilize the maximum nonlinear coefficient of lithium niobate, which isd33~27 pm/V, both the signal light and the pump light are expected to propagate in the...
In the latter case, periodically poled lithium niobate (PPLN) WGM cavities were produced to utilize the largest nonlinear coefficient, d33d33. Because d33d33 is much higher than d31d31 in lithium niobate crystal, PPLN WGM microcavities are more likely to perform nonlinear optical processes in ...

Lithium-niobate-on-insulator (LNOI), as a recently emerging material platform, shows excellent electro-optic, acousto-optic, and nonlinear coefficients [1]. Owing to its high refractive-index difference between core and cladding, LNOI shows great potential for photonic integrated circuits (PIC) and...

Lithium niobate (LN)24–27 has always been an excellent choice of material for THz gen- eration, owing to its high nonlinear coefficient of d33 = 27 pmV−1 28, and low optical losses in the near-infrared. LN's high optical power hand- ling is crucial for optical rectification since ...
Lithium niobate is famous for its large second-order nonlinear coefficient χ(2) and electro-optic coefficient r33. Based on the electro-optic effect of LN, we can achieve various electro-optic devices, among which electro-optic modulator is the most widely used one. Based on the similar prin...
