Quantum Nonlinear Optics with Polar J-Aggregates in Microcavities.

Strong exciton-photon coupling in inorganic-organic multiple quantum wells embedded low-Q microcavity.

Optoelectronic-compatible heterostructures are fabricated from layered inorganic-organic multiple quantum wells (IO-MQW) of Cyclohexenyl ethyl ammonium lead iodide, (C(6)H(9)C(2)H(4)NH(3))(2)PbI(4) (CHPI). These hybrids possess strongly-resonant optical features, are thermally stable and compatible with hybrid photonics assembly. Room-temperature strong-coupling is observed when these hybrids a...

Fabrication, Coupling and Nonlinear Optics of Ultra- High-q Micro-sphere and Chip-based Toroid Microcavities

Semiconductor Optical Microcavities for Chip-Based Cavity QED

Optical microcavities can be characterized by two key quantities: an effective mode volume Veff, which describes the per photon electric field strength within the cavity, and a quality factor Q, which describes the photon lifetime within the cavity. Cavities with a small Veff and a high Q offer the promise for applications in nonlinear optics, sensing, and cavity quantum electrodynamics (cavity...

Tunable resonant optical microcavities by self-assembled templating.

Micrometer-scale optical cavities are produced by a combination of template sphere self-assembly and electrochemical growth. Transmission measurements of the tunable microcavities show sharp resonant modes with Q factors of >300 and 25-fold local enhancement of light intensity. The presence of transverse optical modes confirms the lateral confinement of photons. Calculations show that submicrom...

Many-body physics of a quantum fluid of exciton-polaritons in a semiconductor microcavity

Some recent results concerning nonlinear optics in semiconductor microcavities are reviewed from the point of view of the many-body physics of an interacting photon gas. Analogies with systems of cold atoms at thermal equilibrium are drawn, and the peculiar behaviours due to the non-equilibrium regime pointed out. The richness of the predicted behaviours shows the potentialities of optical syst...
