Engineering of light confinement in strongly scattering disordered media

Disordered photonic materials can diffuse and localize light through random multiple scattering, offering opportunities to study mesoscopic phenomena, control light-matter interactions, and provide new strategies for photonic applications. Light transport ...

Simultaneous near field imaging of electric and magnetic field in photonic crystal nanocavities

Laurent Balet, Massimo Gurioli

The insertion of a metal-coated tip on the surface of a photonic crystal microcavity is used for simultaneous near field imaging of electric and magnetic fields in photonic crystal nanocavities, via the radiative emission of embedded semiconductor quantum ...

Antibonding ground state in photonic crystal molecules

Laurent Balet, Massimo Gurioli

We employ a far-field analysis of the angular emission pattern to experimentally assess the symmetry of localized modes in coupled photonic-crystal cavities. We demonstrate that the spatial distribution of localized modes in photonic-crystal nanocavities m ...

Mode tuning of photonic crystal nanocavities by photoinduced non-thermal oxidation

Laurent Balet, Massimo Gurioli, Santosh Kumar

A method to achieve photoinduced tuning of PhC nanocavity modes is discussed and implemented. It is based on light induced oxidation in air atmosphere with very low thermal budget which produces a local reduction of the GaAs membrane effective thickness an ...

Post-fabrication control of evanescent tunnelling in photonic crystal molecules

Laurent Balet, Massimo Gurioli

The post-fabrication control of evanescent tunnelling in photonic crystal molecules is demonstrated through the combination of selective infiltration and oxidation. By laser non thermal oxidation, we reduce the photonic coupling by more than 30% while by m ...

Ideal homoatomic and heteroatomic photonic crystal molecules

Laurent Balet, Massimo Gurioli

A local tuning of the modes of photonic crystal systems both to blue and to red sides of the resonance is implemented by nano-infiltration/evaporation of water and laser micro-oxidation. This technology is used to completely control coupled photonic nanoca ...

Young's Type Interference for Probing the Mode Symmetry in Photonic Structures

Laurent Balet, Massimo Gurioli

A revisited realization of the Young's double slit experiment is introduced to directly probe the photonic mode symmetry by photoluminescence experiments. We experimentally measure the far field angular emission pattern of quantum dots embedded in photonic ...

Magnetic Imaging in Photonic Crystal Microcavities

Laurent Balet, Massimo Gurioli

We demonstrate the nonresonant magnetic interaction at optical frequencies between a photonic crystal microcavity and a metallized near-field microscopy probe. This interaction can be used to map and control the magnetic component of the microcavity modes. ...

Probing exciton density of states through phonon-assisted emission in GaN epilayers: A and B exciton contributions

Nicolas Grandjean, Jean-François Carlin, Raphaël Butté, Eric Feltin, Massimo Gurioli

A detailed experimental investigation of the phonon-assisted emission in a high-quality c-plane GaN epilayer is presented up to 200 K. By performing photoluminescence and reflectivity measurements, we find important etaloning effects in the phonon-replica ...

Mode hybridization in photonic crystal molecules

Laurent Balet, Massimo Gurioli

A complete control of the coupling between the modes of two photonic crystal microcavities is obtained by using a combination of several local tuning techniques. By a local and controlled modification of one cavity we are able to bring into resonance modes ...
