Static and dynamic properties of multi-section InGaN-based laser diodes

Nicolas Grandjean, Jean-François Carlin, Dmitri Boiko, Julien Dorsaz, Antonino Francesco Castiglia, Luca Alex Milo Sulmoni, Xi Zeng, Jean-Michel Jacques Lamy

We have studied multi-section InGaN multiple-quantum-well (MQW) laser diodes grown on c-plane freestanding GaN substrate consisting of an absorber section (AS) and an amplifier gain section. As a result of the interplay between external bias applied to the ...

Blue lasing at room temperature in high quality factor GaN/AlInN microdisks with InGaN quantum wells

Nicolas Grandjean, Jean-François Carlin, Eric Feltin, Raphaël Butté, Antonino Francesco Castiglia

The authors report on the achievement of optically pumped III-V nitride blue microdisk lasers operating at room temperature. Controlled wet chemical etching of an AlInN interlayer lattice matched to GaN allows forming inverted cone pedestals. Whispering ga ...

InGaN laser diode with metal-free laser ridge using n(+)-GaN contact layers

Nicolas Grandjean, Denis Martin, Antonino Francesco Castiglia, Camille Haller, Marco Rossetti, Marco Malinverni

We report on InGaN edge emitting laser diodes with a top metal electrode located beside the laser ridge. Current spreading over the ridge is achieved via a highly doped n(+)-type GaN layer deposited on top of the structure. The low sheet resistance of the ...

High quality nitride based microdisks obtained via selective wet etching of AlInN sacrificial layers

Nicolas Grandjean, Jean-François Carlin, Eric Feltin, Raphaël Butté, Antonino Francesco Castiglia, Alexei Altoukhov

The authors report a technique for selective wet chemical etching of an AlInN sacrificial layer lattice-matched to GaN for the fabrication of air-gap photonic structures. It is used to demonstrate high quality factor (Q) microdisk cavities. Whispering gall ...

Towards room temperature electrically pumped blue vertical cavity surface emitting lasers

Nicolas Grandjean, Jean-François Carlin, Eric Feltin, Raphaël Butté, Gabriel Christmann, Antonino Francesco Castiglia, Jacques Levrat, Gatien Cosendey, Alexei Altoukhov

The authors report on strategies to achieve lasing in electrically driven vertical cavity surface emitting lasers at room temperature, namely the improvement of the quality factor of a microcavity suited for electrical injection, the use of a ZnO contact t ...

Mg doping for p-type AlInN lattice-matched to GaN

Nicolas Grandjean, Jean-François Carlin, Raphaël Butté, Antonino Francesco Castiglia

P-type AlInN layers lattice-matched to GaN are achieved by Mg doping. The net acceptor concentration N-A-N-D is 5 x 10(18) cm(-3) at a Mg concentration [Mg] of similar to 2 x 10(19) cm(-3). Mg acceptors are partly compensated and one of the compensating de ...

GaN-based laser diodes including a lattice-matched Al0.83In0.17N cladding layer

Nicolas Grandjean, Jean-François Carlin, Eric Feltin, Raphaël Butté, Antonino Francesco Castiglia, Gatien Cosendey

Nitride blue lasers including an AlInN cladding lattice matched to GaN were fabricated. Lasing at 415nm is observed at 300K with a threshold current density of 7.5kA/cm(2) and a peak power of 140mW at 1.2A. (C) 2009 Optical Society of America ...
