Phast: Simultaneous reconstruction of photoelectron count and time profiles from PMT waveforms via machine learning
Yiming Xu, Youwen Fan, Siyu Chen +3
Photomultiplier tubes (PMTs) are widely used in particle and nuclear physics experiments. The reconstruction of PMT waveforms is a fundamental task in these experiments, where accu…
Integrated diode lasers for the generation of sub-GHz repetition rate frequency combs
Anzal Memon, Albert van Rees, Jesse Mak +4
We demonstrate absorber-free passive and hybrid mode-locking at sub-GHz repetition rates using a hybrid integrated extended cavity diode laser around 1550 nm. The laser is based on…
High-purity microwave generation using a dual-frequency hybrid integrated semiconductor-dielectric waveguide laser
Jesse Mak, Albert van Rees, Rob E. M. Lammerink +5
We present an integrated semiconductor-dielectric hybrid dual-frequency laser operating in the 1.5 m wavelength range for microwave and terahertz (THz) generation. Generating a…
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…
