Room temperature polariton luminescence from a GaN/AlGaN quantum well microcavity

Jean-François Carlin, Nicolas Grandjean, Raphaël Butté, Eric Feltin, Mauro Mosca, Gabriel Christmann

The authors report on the demonstration of strong light-matter coupling at room temperature using a crack-free UV microcavity containing GaN/AlGaN quantum wells (QWs). Lattice-matched AlInN/AlGaN distributed Bragg reflectors (DBRs) with a maximum peak refl ...

Lattice-matched distributed Bragg reflectors for nitride-based vertical cavity surface emitting lasers

Jean-François Carlin, Marc Ilegems, Julien Dorsaz, Nicolas Grandjean, Raphaël Butté, Eric Feltin

Very narrow spontaneous emission (Deltalambda similar to 0.5 nm), corresponding to a quality factor Q in excess of 800, has been obtained under continuous-wave excitation at room temperature with an AlInN/GaN monolithic microcavity. The structure is made o ...

Recent progress in the growth of highly reflective nitride-based distributed Bragg reflectors and their use in microcavities

Jean-François Carlin, Marc Ilegems, Julien Dorsaz, Nicolas Grandjean, Raphaël Butté, Eric Feltin, Gabriel Christmann

The growth of highly-reflective nitride-based distributed Bragg reflectors (DBRs) and their use in vertical cavity structures is reviewed. We discuss the various nitride material systems employed to design Bragg mirrors and microcavities, namely the Al-x(G ...

Midinfrared intersubband absorption in lattice-matched AlInN/GaN multiple quantum wells

Jean-François Carlin, Marc Ilegems, Nicolas Grandjean, Raphaël Butté, Eric Feltin, Sylvain Nicolay, Mauro Mosca

We report the observation of midinfrared intersubband (ISB) absorption in nearly lattice-matched AlInN/GaN multiple-quantum-wells. A clear absorption peak is observed around 3 mu m involving transitions from the conduction band ground state to the first ex ...

Progresses in III-nitride distributed Bragg reflectors and microcavities using AlInN/GaN materials

Jean-François Carlin, Julien Dorsaz, Nicolas Grandjean, Raphaël Butté, Eric Feltin, Sylvain Nicolay, Gabriel Christmann

We propose to use lattice-matched AlInN/GaN to replace the Al(Ga)N/GaN material system for III-nitride Bragg reflectors, despite the poor material quality of AlInN reported until very recently. We report an improvement of AlInN material that allowed for su ...

Crack-free fully epitaxial nitride microcavity using highly reflective AllnN/GaN Bragg mirrors

Jean-François Carlin, Marc Ilegems, Julien Dorsaz, Nicolas Grandjean, Raphaël Butté, Eric Feltin

We report the growth over 2 in. sapphire substrates of crack-free fully epitaxial nitride-based microcavities using two highly reflective lattice-matched AlInN/GaN distributed Bragg reflectors (DBRs). The optical cavity is formed by an empty 3lambda/2 GaN ...
