An improved simulation model of switchable dual-wavelength laser has been proposed, with which the different stabilization behaviors with dual-wavelength lasers based on inhomogeneous and homogeneous active media has been analyzed. The numerical results can well explain these actual switching behaviors of a dual-wavelength fiber switchable laser.

Self-assembled lateral InAs quantum dot molecules (QDMs) with InxGa1−xAs strain-reducing layer are grown by metal-organic chemical vapor deposition. A redshift of emission wavelength and wideband photoluminescence spectra of QDMs are observed, which make QDM a potential candidate for broadband optical devices.

A multi-longitudinal-mode fiber laser sensor is proposed and experimentally demonstrated base on beat frequency demodulation. A novel laser cavity is formed only by a FBG, one section of erbium-doped fiber and a broadband reflector. The proposed laser sensor has ultra-stable beat signal due to self-phase matching in the laser cavity.

Lately injectorless quantum cascade lasers are getting more and more into focus of research, as they promise lower threshold current densities and higher output powers and efficiencies. Although the research on them started seven years later in 2001 and was less intensive, they have achieved much lower threshold current densities with 0.45 kA/cm2 at 300 K compared to injectorbased devices. Additionally injectorless devices reached efficiencies and output powers in the important wavelength range between 8 and 12 µm comparable to best performing injectorbased devices. With 2 W per facet and an overall efficiency of 7 % around 9 µm, they show a strong potential regarding possible applications.
