High reflectivity airgap distributed Bragg reflectors realized by wet etching of AlInN sacrificial layers

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

The authors report on the achievement of a vertically oriented three pair airgap/GaN distributed Bragg reflector realized by controlled oxidation and wet-chemical etching of AlInN sacrificial layers. Microreflectivity measurements exhibit high peak reflect ...

Al0.83In0.17N lattice-matched to GaN used as an optical blocking layer in GaN-based edge emitting lasers

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

Nitride-based blue laser diode structures with either Al0.83In0.17N/Al0.07Ga0.93N or Al0.87In0.13N bottom claddings have been fabricated and compared to standard structures including solely Al0.07Ga0.93N bottom claddings. Lasing emission at 415 nm is achie ...
