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 ...

105-ns Continuously Tunable Delay of 10-Gb/s Optical Signal

Camille Sophie Brès

A continuously tunable optical delay line providing over 105 ns of 10-Gb/s optical channel is reported using a two-pump parametric process in a nonlinear optical fiber. Performance limits are measured and compared with recently reported all-optical delay r ...

Seepage and settlement monitoring for earth embankment dams using fully distributed sensing along optical fibers

Luc Thévenaz, Yao Zhou, Pingyu Zhu

A method for seepage and settlement monitoring in earth embankment dams using fully distributed sensing along optical fibres is proposed. A model is developed for simulating and monitoring seepage and settlement systems. This model relates the strains and ...

Optofluidic technologies

Demetri Psaltis, James Adleman

Optofluidics refers to adaptive systems that integrate optical and fluidic devices. Micro and nano-fluidics enable novel devices which introduce liquids into optical structures. We discuss recent optofluidic developments, including optically powered vapor ...
