Abstract
This presentation will present an overview of wave guiding in thin film lithium niobate where surprising polarisation effects can be encountered. Polarisation conversion can occur inherently and this can lead to surprising leakage losses for both TE and TM polarisations and can significantly impact linear functionality including enabling single polarisation guiding in straight waveguides, challenges with achieving low-loss waveguide bends and also efficient second harmonic generation. A number of applications harnessing these effects will also be presented.
