We measure the lasing dynamics of single and coupled photonic crystal nanocavity array lasers fabricated in the indium gallium arsenide phosphide material system. Under short optical excitation, single cavity lasers produce pulses as fast as 11 ps (full wi ...
Optical fiber materials with broad-band gain in the visible or in the telecommunication window are of great interest for optical communication or the biomedical domain in order to built integrated tunable lasers, amplifiers, ultra-short pulse lasers, or br ...
Single frequency lasing from organic dye solutions on a monolithic poly(dimethylsiloxane) (PDMS) elastomer chip is demonstrated. The laser cavity consists of a single mode liquid core/PDMS cladding channel waveguide and a phase shifted 15th order distribut ...
We demonstrated a continuously tunable optofluidic distributed feedback (DFB) dye laser on a monolithic poly(dimethylsiloxane) (PDMS) elastomer chip. The optical feedback was provided by a phase-shifted higher order Bragg grating embedded in the liquid cor ...
We describe a low-power continuous-wave laser system for water-vapour sensing applications in the 935-nm region. The system is based on extended-cavity diode lasers and distributed-feedback lasers and delivers four single-mode frequency-stabilised optical ...
A quantum dot is a semiconductor nanostructure that confines the motion of conduction band electrons and valence band holes in all three spatial directions, thus creating fully discrete energy levels. The confinement in the InAs/GaAs material system is gen ...
We observe the buildup of strong (similar to 50%) spontaneous vector polarization in emission from a GaN-based polariton laser excited by short optical pulses at room temperature. The Stokes vector of emitted light changes its orientation randomly from one ...
Novel 1310 nm and 1550 nm optically pumped VECSELs based on wafer fused InAlGaAs/InPAlGaAs/GaAs gain mirrors demonstrate high CW fundamental mode continuous wave output in excess of 2 W at room temperature. ...

This chapter reviews bicyclic systems containing two fused five-membered rings with one bridgehead nitrogen and two other heteroatoms (nitrogen, oxygen, and sulfur) in each ring. Among the possible structural backbones, 16 have been so far found in the lit ...
Fiber laser systems have the potential to represent an interesting alternative to more conventional laser sources emitting in the visible spectral range. In this contribution we present new results based on fluoride Pr/Yb- doped fiber systems. This Pr/Yb-d ...
