Recent advances in nonlinear optics have revolutionized the area of integrated photonics, providing on-chip solutions to a wide range of new applications. Currently, the state of t…
On-chip polarization rotator for type I second harmonic generation
Eric J. Stanton, Lin Chang, Weiqiang Xie +12
We demonstrate a polarization rotator integrated at the output of a GaAs waveguide producing type I second harmonic generation (SHG). Form-birefringent phase matching between the p…
Improved second harmonic performance in periodically poled LNOI waveguides through engineering of lateral leakage
Andreas Boes, Lin Chang, Markus Knoerzer +4
In this contribution we investigate the impact of lateral leakage for linear and nonlinear optical waveguides in lithium niobate on insulator (LNOI). Silicon nitride (SiN) loaded a…
