Title

Cascaded second-order nonlinearity in nonuniformly temperature tuned LiNbO3 channel waveguide

Abstract

The different temperature scan speeds that can be use to yield different temperature profiles, accordingly different wave-vector mismatch, are investigated in 47-mm long Ti-indiffused LiNbO3 channel waveguides with propagation along the X-axis of a Y-cut crystal. The waveguides are single-mode at the fundamental wavelength λ = 1.32 μm. Temperature phase-matching, around 342 °C, between the fundamental TM00 mode and the second-harmonic TE00 mode is studied. For this purpose, the crystal is placed in an oven capable of achieving temperatures between room-temperature and 450 °C, controlled within a stability of ±25°mK. Waveguide modeling is based on graded-index profiles that are determined by the indiffused Ti concentration profile.
