Impact of Mode-Hopping Noise on InGaN Edge Emitting Laser Relative Intensity Noise Properties

Nicolas Grandjean, Raphaël Butté, Stéphane Trebaol, Antoine Congar

In this paper, we report, through a comparative analysis of static and dynamic measurements, on the impact of mode hopping on the overall intensity noise dynamics of InGaN edge emitting lasers. Mode clustering usually observed in InGaN lasers enhances the ...

Spinor stochastic resonance

Benoît Marie Joseph Deveaud, François Morier-Genoud, Marcia Portella Oberli, Stéphane Trebaol, Hadis Abbaspour

We report on noise-induced spin ordering in a collective quasiparticle system: spinor stochastic resonance. Synergetic interplay of a polarization-modulated signal and a polarization noise allows us to switch coherently between the two metastable states of ...

Effect of a noisy driving field on a bistable polariton system

Benoît Marie Joseph Deveaud, François Morier-Genoud, Marcia Portella Oberli, Stéphane Trebaol, Hadis Abbaspour, Grégory Chilpéric Sallen

We report on the effect of noise on the characteristics of the bistable polariton emission system. The present experiment provides a time-resolved access to the polariton emission intensity. We evidence the noise-induced transitions between the two stable ...

Two-dimensional Fourier transform spectroscopy of exciton-polaritons and their interactions

Benoît Marie Joseph Deveaud, Daniel Oberli, Marcia Portella Oberli, Stéphane Trebaol, Mitchell David Anderson, Naotomo Takemura, Verena Kohnle

We investigate polariton-polariton interactions in a semiconductor microcavity through two-dimensional Fourier transform (2DFT) spectroscopy. We observe, in addition to the lower-lower and the upper-upper polariton self-interactions, a lower-upper cross in ...

Dephasing effects on coherent exciton-polaritons and the breakdown of the strong coupling regime

Benoît Marie Joseph Deveaud, Daniel Oberli, Marcia Portella Oberli, Stéphane Trebaol, Mitchell David Anderson, Naotomo Takemura, Souvik Biswas

Using femtosecond pump-probe spectroscopy, we identify excitation-induced dephasing as a major mechanism responsible for the breakdown of the strong coupling between excitons and photons in a semiconductor microcavity. The effects of dephasing are observed ...

Polaritonic Feshbach resonance

Benoît Marie Joseph Deveaud, Marcia Portella Oberli, Stéphane Trebaol, Naotomo Takemura

A Feshbach resonance occurs when the energy of two interacting free particles comes into resonance with a molecular bound state. When approaching this resonance, marked changes in the interaction strength between the particles can arise. Feshbach resonance ...

Nonlinear relaxation and selective polychromatic lasing of confined polaritons

Benoît Marie Joseph Deveaud, Gabriele Grosso, François Morier-Genoud, Marcia Portella Oberli, Stéphane Trebaol

Polaritons have often been proposed as promising candidates for the realization of all-optical devices due to the easy manipulation and control of their density and spin. In this paper we present a relaxation mechanism for confined polaritons and its appli ...

Stochastic Resonance in Collective Exciton-Polariton Excitations inside a GaAs Microcavity

Benoît Marie Joseph Deveaud, François Morier-Genoud, Marcia Portella Oberli, Stéphane Trebaol, Hadis Abbaspour

We report the first observation of stochastic resonance in confined exciton polaritons. We evidence this phenomena by tracking the polaritons behavior through two stochastic resonance quantifiers namely the spectral magnification factor and the signal-to-n ...

Heterodyne spectroscopy of polariton spinor interactions

Benoît Marie Joseph Deveaud, Marcia Portella Oberli, Stéphane Trebaol, Naotomo Takemura

We report on spinor polariton interactions in GaAs based microcavities. This investigation is carried out by means of heterodyne polarized pump-probe spectroscopy. We show the dependence of the energy renormalization of the lower and upper polariton resona ...
