Control of the properties of micro-structured waveguides in lithium niobate crystal

Opt Express. 2013 Jul 15;21(14):17122-30. doi: 10.1364/OE.21.017122.

Abstract

We study numerically depressed-index cladding, buried, micro-structured optical waveguides that can be formed in a lithium niobate crystal by femtosecond laser writing. We demonstrate to which extent the waveguiding properties can be controlled by the waveguide geometry at the relatively moderate induced refractive index contrasts that are typical of the direct femtosecond inscription.
