Abstract

Periodically poled LiNbO₃ (PPLN) makes available direct and efficient frequency conversion of laser light through quasi-phase matched (QPM) nonlinear optical interactions. For a given PPLN waveguide, the efficiency of frequency conversion strongly depends on QPM, which can be optimized by tuning the wavelength or the temperature. We propose a guided wave device for temperature measurement based on second harmonic generation (SHG) in a PPLN waveguide. Modeling of the device and a preliminary test in a PPLN waveguide fabricated through electric field poling and (APE) annealed proton exchange are reported.
