As surface plasmons waveguides enter the electronic circuitry, surface plasmon (SP) sources are required. Here we demonstrate following attributes of optically pumped SPs laser: threshold, gain, spectral line narrowing, and feedback at 630 nm. The distinction between these attributes and those exhibited by amplified spontaneous emission source are discussed.

    We present a coherent coupling scheme for mid-infrared quantum cascade lasers. Based on far field analysis, fundamental lateral modes are realized in Y-coupled resonators, which are locked in phase. The concept enhances the output power of a single facet coherent emitter, while maintaining good...

    Twenty five years ago Arakawa suggested that by confining carriers in three dimensions (in quantum dots) a temperature insensitive threshold current (Ith) could be achieved in semiconductor lasers. In this paper we discuss investigations on state-of-the-art 1.3 μm InAs/GaAs undoped and...

    Within the framework of perturbation theory, a model is presented to calculate the direct and indirect intraband optical absorption cross-section due to carrier transitions from the quantum dot (QD) level to the continuum states. The results indicate that the phonon-assisted transition process...

    We consider a rate equation model of a quantum dot semiconductor optical amplifier that takes into account carrier capture, escape, and Pauli blocking processes. We evaluate possible differences between phonon-assisted or Auger processes being dominant for recovery. An analytical solution which...

    We report on two-color InAs/InP(100) quantum dot lasers with tunable wavelength gap. Two peaks of lasing emission were observed simultaneously, while the high energy peak undergoes continuous blueshift with the increase in the injection current, and the low energy peak is somewhat fixed....

    The effect of external optical feedback on an InAs/GaAs quantum dot passively mode-locked laser is investigated. The rf linewidth narrows from 8 KHz in the free-running situation to a value as low as 350 Hz under relatively low feedback. The rf linewidth characterization under resonant feedback...
