Chris G. H. Roeloffzen,Marcel Hoekman,Edwin J. Klein,Lennart Wevers,R. B. Timens,Denys Marchenko,Dimitri Geskus,Ronald Dekker,Andrea Alippi,Robert Grootjans,Albert van Rees,Ruud M. Oldenbeuving,Jörn P. Epping,Rene Heideman,Kerstin Worhoff,Arne Leinse,Douwe Geuzebroek,Erik Schreuder,Paulus W. L. van Dijk,Ilka Visscher,Caterina Taddei,Youwen Fan,Caterina Taballione,Yang Liu,David Marpaung,Leimeng Zhuang,Meryem Benelajla,Klaus J. Boller +27 more
TL;DR: An overview of the most recent developments and improvements to the low-loss TriPleX Si3N4 waveguide technology is presented in this article, which can be combined to design complex functional circuits, but more important are manufactured in a single monolithic flow to create a compact photonic integrated circuit.

On-chip visible-to-infrared supercontinuum generation with more than 495 THz spectral bandwidth.
Jörn P. Epping,Tim Hellwig,Marcel Hoekman,Richard Mateman,Arne Leinse,Rene Heideman,Albert van Rees,Peter J. M. van der Slot,Christopher James Lee,Carsten Fallnich,Klaus J. Boller +10 more
TL;DR: The ultra-broadband supercontinuum generation in high-confinement Si3N4 integrated optical waveguides is reported, comprising a spectral bandwidth wider than 495 THz, which is the widestsupercontinuum spectrum generated on a chip.
Journal ArticleDOI
High confinement, high yield Si3N4 waveguides for nonlinear optical applications
Jörn P. Epping,Marcel Hoekman,Richard Mateman,Arne Leinse,Rene Heideman,Albert van Rees,Peter J. M. van der Slot,Christopher James Lee,Klaus J. Boller +8 more
TL;DR: Using this technique no stress-induced cracks in the Si(3)N(4) layer were observed resulting in a high yield of devices on the wafer, and propagation losses of the obtained waveguides were measured to be as low as 0.4 dB/cm at a wavelength of around 1550 nm.
Journal ArticleDOI
Hybrid integrated InP-Si3N4 diode laser with a 40-Hz intrinsic linewidth.
Youwen Fan,Albert van Rees,Peter J. M. van der Slot,Jesse Mak,Ruud M. Oldenbeuving,Marcel Hoekman,Dimitri Geskus,Chris G. H. Roeloffzen,Klaus J. Boller +8 more
TL;DR: 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 circuit that extends the cavity length to 0.5 meter on a chip is demonstrated.

TL;DR: In this article, a hybrid integrated diode laser source with feedback from low-loss silicon nitride (Si3N4 in SiO2) circuits is presented, achieving sub-100-Hz-level intrinsic linewidths, up to 120 nm spectral coverage around a 1.55 μm wavelength, and an output power above 100 mW.
