متن کاملAsymmetric line broadening in intracavity loss modulated quantum well distributed feedback lasers
We report for the first time high-speed (Gbit s ‘), single mode, digital (on-off) modulation of intracavity loss modulated 1.55 pm InGaAs/InP multiple quantum well distributed feedback lasers. The lasing spectrum, observed to be asymmetrically broadened under high-speed modulation, is shown to result from large carrier density variations which accompany this switching scheme. We also show, for ...
متن کاملMicrofluidic tuning of distributed feedback quantum cascade lasers.
In this Letter, we report the tuning of the emission wavelength of a single mode distributed feedback quantum cascade laser by modifying the mode effective refractive index using fluids. A fabrication procedure to encapsulate the devices in polymers for microfluidic delivery is also presented. The integration of microfluidics with semiconductor laser (optofluidics) is promising for new compact ...
متن کاملHeterogeneously Integrated Distributed Feedback Quantum Cascade Lasers on Silicon
Silicon integration of mid-infrared (MIR) photonic devices promises to enable low-cost, compact sensing and detection capabilities that are compatible with existing silicon photonic and silicon electronic technologies. Heterogeneous integration by bonding III-V wafers to silicon waveguides has been employed previously to build integrated diode lasers for wavelengths from 1310 to 2010 nm. Recent...
متن کاملPhotoacoustic spectroscopy with quantum cascade distributed-feedback lasers.
We present photoacoustic (PA) spectroscopy measurements of carbon dioxide, methanol, and ammonia. The light source for the excitation was a single-mode quantum cascade distributed-feedback laser, which was operated in pulsed mode at moderate duty cycle and slightly below room temperature. Temperature tuning resulted in a typical wavelength range of 3cm(-1)at a linewidth of 0.2cm(-1). The setup ...
