Intrinsic degradation mechanism of nearly lattice-matched InAlN layers grown on GaN substrates

Nicolas Grandjean, Jean-François Carlin, Raphaël Butté, Gatien Cosendey

Thanks to its high refractive index contrast, band gap, and polarization mismatch compared to GaN, In0.17Al0.83N layers lattice-matched to GaN are an attractive solution for applications such as distributed Bragg reflectors, ultraviolet light-emitting diod ...

Q-factor of (In,Ga)N containing III-nitride microcavity grown by multiple deposition techniques

Nicolas Grandjean, Jean-François Carlin, Raphaël Butté, Jacques Levrat, Gatien Cosendey, Georg Rossbach, Marlene Glauser

A 3 lambda/2 (In,Ga)N/GaN resonant cavity, designed for similar to 415nm operation, is grown by molecular beam epitaxy and is sandwiched between a 39.5-period (In,Al)N/GaN distributed Bragg reflector (DBR), grown on c-plane GaN-on-sapphire pseudo-substrate ...

Analysis of structurally sensitive loss in GaN-based VCSEL cavities and its effect on modal discrimination

Nicolas Grandjean, Gatien Cosendey, Ehsan Hashemi

Lateral loss causes optical energy to leave the laser cavity in the transverse, lateral, direction, and is sometimes neglected to simplify the numerical simulations. However, in contrast to outcoupling and absorption losses, we show that the lateral loss c ...
