Nanosecond colloidal quantum dot lasers for sensing.
Low-threshold, gain switched colloidal quantum dot (CQD) distributed-feedback lasers operating in the nanosecond regime are reported and proposed for sensing applications for the first time to the authors' knowledge. The lasers are based on a mechanically-flexible polymeric, second order grating structure overcoated with a thin-film of CQD/PMMA composite. The threshold fluence of the resulting ...
متن کاملSimulation of Direct Pumping of Quantum Dots in a Quantum Dot Laser
In this paper, the nonlinear rate equations governing a quantum dot laser isused to simulate the transient as well as the steady-state behaviors of the laser.Computation results show that the rate equations are capable of simulating true behaviorof a quantum dot laser. Then, the pump rates of the rate equations (which show indirectelectrical pumping of the quantum dots through a wetting layer) ...
متن کاملSingle mode optofluidic distributed feedback dye laser.
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 distributed feedback (DFB) structure. A 1mM solution of Rhodamine 6G in a methanol and ethylene glycol mixture was used as the gain medium. Using 6 na...

متن کاملControl over spectral content via differential pumping of a monolithic passively mode-locked quantum dot laser
A monolithic two-section quantum dot semiconductor laser is differentially pumped to form non-uniform current injection in the gain region. We show that the nature of the spectral content in the output signal is affected by this differential pumping; despite the fact that the separately pumped gain regions are not electrically isolated in this device. Both negative (red-shift) and positive (blu...
