Wavelength modulation spectroscopy: combined frequency and intensity laser modulation

A theoretical model of wavelength modulation spectroscopy that uses a laser diode on a Lorentzian absorption line is presented. This theory describes the general case of a current-modulated semiconductor laser for which a combined intensity and frequency m ...

Parallel optical coherence tomography in scattering samples using a two-dimensional smart-pixel detector array

René Salathé, Theo Lasser, Boris Clément Karamata, Stéphane Bourquin, Markus Laubscher

Parallel optical coherence tomography in scattering samples is demonstrated using a 58 x 58 smart-pixel detector array. A femtosecond mode-locked Ti:Sapphire laser in combination with a free space Michelson interferometer was employed to achieve 4 mum long ...

Ethylene spectroscopy using a quasi-room-temperature quantum cascade laser

Luc Thévenaz, Philippe Robert

Spectroscopic measurements on ethylene were performed using a quasi-room-temperature quantum cascade (QC) laser operated in pulsed mode in the 10.3 μm range. Using transmission spectroscopy, a broadening of the ethylene absorption spectrum was observed wit ...

Net coherent optical gain in strongly pumped semiconductor microcavities

Benoît Marie Joseph Deveaud, Ursula Oesterle, Cristiano Ciuti, Michele Saba

We study the subpicosecond gain dynamics in a high-finesse semiconductor microcavity containing quantum wells by means of degenerate pump-probe spectroscopy. Tuning the optical excitation in resonance with both the exciton and the cavity modes, at high pum ...

Observation of dark-pulse formation in gain-clamped semiconductor optical amplifiers by cross-gain modulation

Benoît Marie Joseph Deveaud, Marc-André Dupertuis

We have measured the ultrafast simultaneous cross-gain and laser mode dynamics in a gain-clamped semiconductor amplifier perturbed by an intense detuned 150 fs pump pulse. Besides relaxation oscillations, we demonstrate the instantaneous formation of a dar ...

Resonant Rayleigh scattering versus incoherent luminescence in semiconductor microcavities

Romuald Houdré, Benoît Marie Joseph Deveaud, Ursula Oesterle

It is demonstrated that during the first few picoseconds after resonant femtosecond excitation the secondary radiation from a strongly coupled semiconductor microcavity containing one quantum well is dominated by Rayleigh scattered light. At early times af ...

Conception and realization of a compact scanning near-field optical microscope

Combining the subwavelength resolution of near-field interactions with the optical contrast mechanisms of classical optical microscopy makes scanning near-field optical microscopy an interesting technique for many applications. In spite of more than ten ye ...

Highly efficient optically pumped NH3 laser with near diffraction limited output

Thomas Rizzo, Joachim Makowe

We present the design of a highly efficient, pulsed ammonia laser which is optically pumped by a commercial TEA CO2 laser and is line tunable in the spectral range of 780-930 cm(-1). The power, spectral, and temporal characteristics of the laser have been ...

L'émission laser par diffusion Brillouin stimulée dans les fibres optiques

Among all scattering processes, spontaneous Brillouin scattering originates from the interaction between light and thermal acoustic waves propagating in the medium. The interference resulting from the incident light and its spontaneously backscattered frac ...

Structural and optical characterization of InP/InGaAsP distributed Bragg reflectors grown by CBE

Elyahou Kapon, Jean-François Carlin, Alok Rudra

High quality InP/InGaAsP Distributed Bragg Reflectors (DBRs) are a key element in Vertical Cavity Surface Emitting Laser (VCSELs) for long wavelength (1.55 mu m) applications [1-3]. Because of the small index difference between InP and InGaAsP, more than 3 ...
