Emulating the local Kuramoto model with an injection-locked photonic crystal laser array
Naotomo Takemura, Kenta Takata, Masato Takiguchi +1
The Kuramoto model is a mathematical model for describing the collective synchronization phenomena of coupled oscillators. We theoretically demonstrate that an array of coupled pho…
Designs toward synchronization of optical limit cycles with coupled silicon photonic crystal microcavities
Naotomo Takemura, Masato Takiguchi, Masaya Notomi
A driven high-Q Si microcavity is known to exhibit limit cycle oscillation originating from carrier-induced and thermo-optic nonlinearities. We propose a novel nanophotonic device…
Photon correlation measurements of stochastic limit cycles emerging from high- nonlinear silicon photonic crystal microcavities
N. Takemura, M. Takiguchi, H. Sumikura +3
We performed measurements of photon correlation [] in driven nonlinear high- silicon (Si) photonic crystal (PhC) microcavities. The measured exhibits a…
Probing the Ginzburg-Landau Potential for Lasers Using Higher-order Photon Correlations
Naotomo Takemura, Masato Takiguchi, Masaya Notomi
Lasing transition is known to be analogous to the second-order phase transition. Furthermore, for some cases, it is possible to define the Ginzburg-Landau (GL) potential, and the G…
Low- and high- lasers in Class-A limit: photon statistics, linewidth, and the laser-phase transition analogy
Naotomo Takemura, Masato Takiguchi, Masaya Notomi
Nanocavity lasers are commonly characterized by the spontaneous coupling coefficient that represents the fraction of photons emitted into the lasing mode. While is conventi…
Cross Feshbach resonance
M. Navadeh-Toupchi, N. Takemura, M. D. Anderson +2
Feshbach resonance occurs when a pair of free particles is resonantly coupled to a molecular bound state. In the field of ultracold quantum gases, atomic Feshbach resonances became…
Giant paramagnetism induced valley polarization of electrons in charge-tunable monolayer MoSe2
Patrick Back, Meinrad Sidler, Ovidiu Cotlet +4
For applications exploiting the valley pseudospin degree of freedom in transition metal dichalcogenide monolayers, efficient preparation of electrons or holes in a single valley is…
Spin anisotropic interactions of lower-polaritons in the vicinity of polaritonic Feshbach resonance
N. Takemura, M. D. Anderson, M. Navadeh-Toupchi +3
We determine experimentally the spinor interaction constants of lower-polaritons and using resonant pump-probe spectroscopy with a spectrally narrow pump pulse. Our exp…
Coherent and incoherent aspects of polariton dynamics in semiconductor microcavities
N. Takemura, M. D. Anderson, S. Biswas +4
The interaction between coherent polaritons and incoherent excitons plays an important role in polariton physics. Using resonant pump-probe spectroscopy with selective excitation o…
Dephasing effects on coherent exciton-polaritons and the breaking of the strong coupling regime
Naotomo Takemura, Stéphane Trebaol, Anderson Mitchell David +4
Using femtosecond pump-probe spectroscopy, we identify excitation induced dephasing as a major mechanism responsible for the breaking of the strong-coupling between excitons and ph…
2D Fourier Transform Spectroscopy of exciton-polaritons and their interactions
N. Takemura, S. Trebaol, M. D. Anderson +5
We investigate polariton-polariton interactions in a semiconductor microcavity through two-dimensional Fourier transform (2DFT) spectroscopy. We observe, in addition to the lower-l…
Polaritonic Feshbach Resonance
Naotomo Takemura, Stéphane Trebaol, Michiel Wouters +2
A Feshbach resonance occurs when the energy of two interacting free particles comes to resonance with a molecular bound state. When approaching this resonance, dramatic changes in…
Heterodyne Spectroscopy of Polariton Spinor Interactions
Naotomo Takemura, Stéphane Trebaol, Michiel Wouters +2
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 depe…
