Room-temperature polariton lasing in semiconductor microcavities

Nicolas Grandjean, Jean-François Carlin, Raphaël Butté, Eric Feltin, Gabriel Christmann

We observe a room-temperature low-threshold transition to a coherent polariton state in bulk GaN microcavities in the strong-coupling regime. Nonresonant pulsed optical pumping produces rapid thermalization and yields a clear emission threshold of 1 mW, co ...

Optical mode control in VCSEL-based photonic crystal heterostructures

Lars Lundeberg

The field of photonic crystals is a rapidly developing branch of modern optics. Photonic crystals are believed to be the cornerstone for a wide range of new photonic devices controlling the confinement and propagation of light. These artificial structures ...

Tunable optofluidic distributed feedback dye lasers

Demetri Psaltis

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 ...

Mechanically tunable optofluidic distributed feedback dye laser

Demetri Psaltis

A continuously tunable optofluidic distributed feedback (DFB) dye laser was demonstrated on a monolithic replica molded poly(dimethylsiloxane) (PDMS) chip. The optical feedback was provided by a phase-shifted higher order Bragg grating embedded in the liqu ...

Single mode optofluidic distributed feedback dye laser

Demetri Psaltis

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 ...

An all-fiber Pr/Yb-doped up-conversion laser in different laser operation modes

Theo Lasser, Hans Georg Limberger, Marcel Zeller

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 ...

Photonic crystal nanocavity array laser

Hatice Altug

We demonstrate a new type of laser composed of an array of coupled photonic crystal nanocavities that enables high differential quantum efficiency and output power, together with a low threshold power comparable to those of single photonic crystal cavity l ...

Coupled photonic crystal microcavity array laser

Hatice Altug

We designed a new laser composed of two-dimensional coupled photonic crystal microcavity arrays. In these structures we have observed single mode lasing with power conversion efficiency 10 times better than a single microcavity laser. ...

Study of vertical coupled-cavity laser structures

This thesis addresses general aspects of the operation of a coupled-cavity vertical surface-emitting laser (CC-VCSEL) which consists of two active cavities optically coupled and independently electrically pumped. The first two chapters of the thesis deal w ...

Rate-equation model for coupled-cavity surface-emitting lasers

Jean-François Carlin, Marc Ilegems

We present a detailed theoretical study of a vertical-cavity surface-emitting laser (VCSEL) with two optically coupled, active cavities. The study is based on a rate-equation model written for carriers and photons under steady-state conditions. The model a ...
