Presentation

The activity of the PEQ group aims at the investigation, the understanding and the exploitation of optical phenomena that occur when the electromagnetic field is confined in a semiconductor in dimensions of the order of the optical wavelength. This activity relies on the quantum mechanical or nonlinear effects that take place under strong confinement to design, realize, and study photonic devices with specific characteristics, unattainable by other means.

The four actions of the PEQ group correspond to the investigation of the behavior of light in a semiconductor in four different types of conditions:

	Action AutoOrg : Optical Self-Organisation and Cavity Solitons Strong intensities (1 kW/cm2), producing nonlinear optical phenomena and in particular self-organization and solitons.
	Action OQS: Quantum Optics in Semiconductors Light and matter interaction at the nanoscale, for nanosources of quantum states of light, nanoscale lasers and cavity nano-optomechanics.
	Action COMS: Emission control and THz sources Frequencies bordering with microwaves (100 GHz), leading to the realization of THz sources, as well as photo-oscillators for the optical transposition at 1.55 µm of radio signals at 60 GHz.
	Action Guidon: Discrete photonics in structured coupled waveguide arrays Waveguide arrays where the coupling constant between individual waveguides is locally modulated. This modulation leads to specific discrete behaviors with fundamental interest and all optical signal processing applications.
