    We describe simple, self-aligned, index-guided arrays containing up to 10 ridge waveguide lasers. The Ohmic contact and current confining Schottky barrier are provided by a single broad area metallization. This technique requires only a single growth on a planar (100) substrate and is compatible...

    A simple cubic-shaped cavity with a high-diffuse-reflectivity inner coating as a novel gas detection cell was developed. The effective optical path length (EOPL) was evaluated by comparing the oxygen absorption signal in the cavity and in air based on tunable diode laser absorption spectroscopy....

    We have theoretically investigated the thermal characteristics of double-channel ridge–waveguide InGaAs/InAlAs/InP quantum cascade lasers (QCLs) using a two-dimensional heat dissipation model. The temperature distribution, heat flow, and thermal conductance ( G th) of QCLs were obtained...

    A room temperature external grating cavity (EGC) quantum cascade laser (QCL) is characterized using saturation spectroscopy of NO2. The presence of two strong EGC QCL waveguide modes is evident from the saturation spectra. A linewidth of 21 MHz for each EGC-QCL mode is measured from the width of...

    Influence of the spectral linewidth Δν of a semiconductor laser on the performance of a fiber-optic laser Doppler velocimeter (FLDV) was investigated. By using an external-cavity laser with Δν[bar_over_tilde:_approx._equal_to]0.3 MHz, we could build a FLDV having an optical fiber...

    We propose an electrically-pumped hybrid plasmonic laser through the integration of a semiconductor quantum well laser with a thin metal film. Due to the coupling between the TM waveguide mode in the III-V active layer and the LRSPP mode around the metal thin film, light can be confined in both...

    The waveguide effect of GaAsSb quantum wells in a semiconductor-laser structure based on GaAs is studied theoretically and experimentally. It is shown that quantum wells themselves can be used as waveguide layers in the laser structure. As the excitation-power density attains a value of 2 kW/cm...

    Different measures to improve the modulation efficiency of a distributed Bragg reflector tapered diode laser emitting at 1060 nm were investigated. Due to the 6-mm long cavity, the device reached an output power of 10 W with a nearly diffraction-limited beam quality. The input currents to the...
