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…
Automatic Delay Tuning of a Novel Ring Resonator-based Photonic Beamformer for a Transmit Phased Array Antenna
L. Bliek, S. Wahls, I. Visscher +5
We present a novel photonic beamformer for a fully integrated transmit phased array antenna, together with an automatic procedure for tuning the delays in this system. Such an auto…
