Soliton dual frequency combs in crystalline microresonators

Tobias Kippenberg, Maxim Karpov, Erwan Guillaume Albert Lucas

We present a novel compact dual-comb source based on a monolithic optical crystalline MgF2 multi-resonator stack. The coherent soliton combs generated in the two microresonators of the stack with the repetition rate of 12.1 GHz and difference of 1.62 MHz p ...

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

Tobias Kippenberg, Martin Hubert Peter Pfeiffer, Nicolas Volet

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. ...

Dependence of a microresonator Kerr frequency comb on the pump linewidth

Tobias Kippenberg, Maxim Karpov, Martin Hubert Peter Pfeiffer, Arne Kordts

We experimentally investigate the dependence of Kerr comb generation, comb linewidth, and coherent system performance on the pump linewidth in a microresonator. We find that the generation of the primary comb can have a larger tolerance to the pump linewid ...

Experimental Demonstration of 7-fold Multicasting of a 20-Gbaud QPSK Signal using Kerr Frequency Combs

Tobias Kippenberg, Maxim Karpov, Martin Hubert Peter Pfeiffer, Arne Kordts, Yan Yan, Zhe Zhao

We experimentally demonstrate 7-fold multicasting of 20-Gbaud QPSK signals based on Kerr frequency combs generated in a silicon nitride microresonator. The effect of high phase-noise comb state on the multicasting performance has also been studied. ...

Small-signal transient response and turn-on delay of polariton laser diodes

Raphaël Butté

We present a theoretical description of the small-signal transient response of polariton laser diodes (pol-LDs) based on simplified coupled rate equations describing the exciton reservoir and the ground-state polariton populations. The analytic expressions ...

Spatial multistability induced by cross interactions of confined polariton modes

Benoît Marie Joseph Deveaud, Daniel Oberli, François Morier-Genoud, Marcia Portella Oberli, Claudéric Ouellet-Plamondon, Grégory Chilpéric Sallen

We demonstrate the occurrence of spatial multistability using laterally confined microcavity exciton-polaritons. By coherently exciting with a blue detuned laser a series of confined polariton modes, we investigate the effects of multistability on the tran ...

Frequency comb generation in the green using silicon nitride microresonators

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

Optical frequency combs enable precision measurements in fundamental physics and have been applied to a growing number of applications, such as molecular spectroscopy, LIDAR and atmospheric trace-gas sensing. In recent years, the generation of frequency co ...

Frequency combs and platicons in optical microresonators with normal GVD

Tobias Kippenberg

We predict the existence of a novel type of the flat-top dissipative solitonic pulses, "platicons", in microresonators with normal group velocity dispersion (GVD). We propose methods to generate these platicons from cw pump. Their duration may be altered s ...

Perspectives of Active Atomic Clock Based on Modelocked Semiconductor Laser with Rubidium Vapor Cell Saturable Absorber

Xi Zeng

Atomic clocks are a vital technology in the day to day operation of modern society. While passive Rb and Cs microwave atomic clocks find widespread practical applications today, active atomic clocks have the potential to surpass them in frequency stability ...

Counting the cycles of light using a self-referenced optical microresonator

Tobias Kippenberg, Martin Hubert Peter Pfeiffer, Victor Brasch, Tobias Herr, John David Jost, Caroline Marie Anne Lecaplain

Phase coherently linking optical-to-radio frequencies with femtosecond mode-locked laser frequency combs has enabled counting the cycles of light and is the basis of optical clocks, absolute frequency synthesis, tests of fundamental physics, and improved s ...

Molecular Optomechanics with Plasmons: Backaction at the nanoscale

Tobias Kippenberg, Christophe Marcel Georges Galland, Nicolas Piro Mastracchio

The plasmonic systems used in surface-enhanced Raman scattering are shown to be quivalent to optomechanical cavities. The new backaction force of the plasmon on the molecular vibration could lead to coherent amplification of vibrational motion. ...
