GaN-based superluminescent diodes with long lifetime

Nicolas Grandjean, Jean-François Carlin, Antonino Francesco Castiglia

We report on the reliability of GaN-based super-luminescent light emitting diodes (SLEDs) emitting at a wavelength of 405 nm. We show that the Mg doping level in the p-type layers has an impact on both the device electro-optical characteristics and their r ...

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

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

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 ...

InGaN laser diodes emitting at 500 nm with p-layers grown by molecular beam epitaxy

Nicolas Grandjean, Julien Dorsaz, Eric Feltin, Antonino Francesco Castiglia, Marco Malinverni, Jean-Michel Jacques Lamy, Marco Rossetti, Lise Lahourcade, Denis Martin

We demonstrate hybrid laser diodes by combining n-type layers and an active region grown by metal organic vapor phase epitaxy with p-type layers grown by molecular beam epitaxy. These p-doped layers, grown at 740 degrees C, exhibit state-of-the-art electri ...

Low temperature p-type doping of (Al)GaN layers using ammonia molecular beam epitaxy for InGaN laser diodes

Nicolas Grandjean, Julien Dorsaz, Eric Feltin, Antonino Francesco Castiglia, Marco Malinverni, Jean-Michel Jacques Lamy, Denis Martin

We demonstrate state-of-the-art p-type (Al) GaN layers deposited at low temperature (740 degrees C) by ammonia molecular beam epitaxy (NH3-MBE) to be used as top cladding of laser diodes (LDs) with the aim of further reducing the thermal budget on the InGa ...

Blue monolithic AlInN-based vertical cavity surface emitting laser diode on free-standing GaN substrate

Nicolas Grandjean, Jean-François Carlin, Antonino Francesco Castiglia, Gatien Cosendey, Georg Rossbach

We report on III-nitride based blue vertical cavity surface emitting lasers using defect-free highly reflective AlInN/GaN distributed Bragg reflectors grown on c-plane free-standing GaN substrates. Lasing is demonstrated at room temperature under pulsed el ...

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

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

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 ...

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 ...

High quality factor two dimensional GaN photonic crystal cavity membranes grown on silicon substrate

Nicolas Grandjean, Romuald Houdré, Jean-François Carlin, Raphaël Butté, Jacques Levrat, Antonino Francesco Castiglia, Kirill Atlasov, Georg Rossbach, Noelia Vico Triviño, Ulagalandha Perumal Dharanipathy

We report on the achievement of freestanding GaN photonic crystal L7 nanocavities with embedded InGaN/GaN quantum wells grown by metal organic vapor phase epitaxy on Si (111). GaN was patterned by e-beam lithography, using a SiO2 layer as a hard mask, and ...

Role of stable and metastable Mg-H complexes in p-type GaN for cw blue laser diodes

Nicolas Grandjean, Jean-François Carlin, Antonino Francesco Castiglia

Secondary ion mass spectroscopy (SIMS) and capacitance-voltage measurements were combined to thoroughly study Mg doping in GaN layers grown by metal organic vapor phase epitaxy. First we found that the Mg steady-state incorporation regime occurs for a surf ...

High Power Blue-Violet Superluminescent Light Emitting Diodes with InGaN Quantum Wells

Nicolas Grandjean, Jean-François Carlin, Julien Dorsaz, Eric Feltin, Antonino Francesco Castiglia, Gatien Cosendey, Marco Rossetti

We report on the characteristics of blue superluminescent light emitting diodes based on the emission of InGaN quantum wells. Narrow ridge-waveguide devices realized by standard processing techniques and with extremely low facet reflectivity show single la ...
