Integrated Si3N4 Soliton Microcomb Driven by a Compact Ultra-low-noise Laser

Tobias Kippenberg, Rui Ning Wang, Nicolas Volet, Junqiu Liu, Erwan Guillaume Albert Lucas, Arslan Sajid Raja, Jijun He

We generate 100-GHz soliton microcombs in a photonic integrated high-Q Si3N4 microresonator using an ultra-compact, high-power and low-frequency-noise semiconductor-based laser. The soliton is initiated via direct current tuning of the laser. (C) 2019 The ...

An optical-frequency synthesizer using integrated photonics

Tobias Kippenberg, Nicolas Volet, Martin Hubert Peter Pfeiffer

Optical-frequency synthesizers, which generate frequency-stable light from a single microwave-frequency reference, are revolutionizing ultrafast science and metrology, but their size, power requirement and cost need to be reduced if they are to be more wid ...

Heterogeneous integration of lithium niobate and silicon nitride waveguides for wafer-scale photonic integrated circuits on silicon

Tobias Kippenberg, Michail Zervas, Nicolas Volet, Martin Hubert Peter Pfeiffer

An ideal photonic integrated circuit for nonlinear photonic applications requires high optical nonlinearities and low loss. This work demonstrates a heterogeneous platform by bonding lithium niobate (LN) thin films onto a silicon nitride (Si3N4) waveguide ...

Towards an Integrated-Photonics Optical-Frequency Synthesizer With < 1 Hz Residual Frequency Noise

Tobias Kippenberg, Nicolas Volet, Martin Hubert Peter Pfeiffer

We introduce an architecture for optical-frequency synthesis using photonic-chip frequency combs and a heterogeneously integrated CW laser. The Kerr dual-comb that we describe offers a microwave-optical link to discipline the laser to an RF clock. ...

Chip-scale Optical Resonator Enabled Synthesizer (CORES) Miniature systems for optical frequency synthesis

Tobias Kippenberg, Nicolas Volet, Hairun Guo, Martin Hubert Peter Pfeiffer

An approach for a low-power chip-scale package is described, that provides a laser output with a programmable frequency across 50 nm of bandwidth centered at 1550 nm, and a resolution of one part in 10(14). ...

Generation of an optical frequency comb in the green with silicon nitride microresonators

Tobias Kippenberg, Michail Zervas, Nicolas Volet, Hairun Guo, Martin Hubert Peter Pfeiffer

The first realization of a green-light frequency comb is reported in a silicon nitride ring microresonator, from third-order non-linear interaction of a near-infrared 1-THz spacing Kerr comb spanning 2/3 of an octave. ...

Recent progress in wafer-fused VECSELs emitting in the 1310 nm waveband

Elyahou Kapon, Nicolas Volet, Alexandru Mereuta, Vladimir Iakovlev, Alexei Sirbu, Andrei Caliman

Over the last years we have continuously improved the performance of 1300 nm band VECSELs with wafer fused gain mirrors in the intra-cavity diamond and the flip-chip heat dissipation configurations. In this work we present recent results for gain mirrors t ...

High performance wafer-fused semiconductor disk lasers emitting in the 1300 nm waveband

Elyahou Kapon, Nicolas Volet, Alexandru Mereuta, Vladimir Iakovlev, Alexei Sirbu, Andrei Caliman

We report for the first time on the performance of 1300 nm waveband semiconductor disc lasers (SDLs) with wafer fused gain mirrors that implement intracavity diamond and flip-chip heat dissipation schemes based on the same gain material. With a new type of ...
