Ring resonator enhanced mode-hop-free wavelength tuning of an integrated extended-cavity laser
Albert van Rees, Youwen Fan, Dimitri Geskus +4
Extending the cavity length of diode lasers with feedback from Bragg structures and ring resonators is highly effective for obtaining ultra-narrow laser linewidths. However, cavity…

High confinement, high yield Si3N4 waveguides for nonlinear optical application
Jörn P. Epping, Marcel Hoekman, Richard Mateman +6
In this paper we present a novel fabrication technique for silicon nitride (Si3N4) waveguides with a thickness of up to 900 nm, which are suitable for nonlinear optical application…
