A hybrid-integrated diode laser in the visible spectral range
Cornelis A. A. Franken, Albert van Rees, Lisa V. Winkler +7
Generating visible light with wide tunability and high coherence based on photonic integrated circuits is of high interest for applications in biophotonics, precision metrology and…
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…
Hybrid integrated semiconductor lasers with silicon nitride feedback circuits
Klaus-J. Boller, Albert van Rees, Youwen Fan +17
Hybrid integrated semiconductor laser sources offering extremely narrow spectral linewidth as well as compatibility for embedding into integrated photonic circuits are of high impo…
Ultra-narrow linewidth hybrid integrated semiconductor laser
Youwen Fan, Albert van Rees, Peter J. M. van der Slot +6
We demonstrate a hybrid integrated and widely tunable diode laser with an intrinsic linewidth as narrow as 40 Hz, achieved with a single roundtrip through a low-loss feedback circu…
Integrated frequency comb laser with narrow intrinsic optical linewidth based on a dielectric waveguide feedback circuit
Jesse Mak, Albert van Rees, Youwen Fan +4
We present an integrated hybrid semiconductor-dielectric (InP-SiN) waveguide laser that generates frequency combs at a wavelength around 1.5 m with a record-low intrinsi…
