“…Several approaches have been proposed to increase the output power of single-spatial-mode lasers. For instance, an output beam from a narrow stripe edge-emitting laser can be boosted by an external optical amplifier [22,23]. However, such a system is complicated and costly, whereas its total efficiency is quite low.…”

Simple analytical expressions for the shape and width of the multi-frequency lasing spectra of quantum dot lasers are derived by using a parabolic approximation of the gain spectrum. A giant nonlinear gain coefficient of 2.5 × 10 −15 cm 3 was estimated from the experimental dependence of the lasing spectrum width on the output power. A monolithic diffraction optical filter was used to suppress lasing of higher-order transverse modes in a quantum dot laser with a relatively broad ridge waveguide. Stable lasing on a fundamental transverse mode is observed with the maximum continuous wave (CW) single-spatial-mode power of 700 mW.

“…instabilities, as has been demonstrated in work carried out on tapered structures including master oscillators-power amplifiers (Donnelly et al 1998;Selmic et al 2002), cavity spoiling features (Donnelly et al 1998;Selmic et al 2002), laterally profiled facets Stryckman et al (1996), patterned contacts Salet et al (1998), unstable resonators Tilton et al (1991), and angled DFB structures Lang et al (1998). However, these techniques largely rely on the use of low-fabrication-tolerance elements reducing the yields, so alternative designs for stable high-power lasers attract considerable interest, with selective quantum well intermixing proposed as an attractive method Kowalski (2005).…”

A numerical model in terms of rate equations for lateral mode amplitudes for analysing static and dynamic properties of moderately broad stripe (tens of microns) laser diodes is proposed and used for modeling lasers with longitudinally or laterally intermixed passive areas. Introduction of passive diffractive regions is shown to offer some improvement of the laser beam, and the potential of further improvement of the beam by Intermixing lateral fringes along the stripe is discussed.

These devices can potentially reduce system costs by simplifying optical alignment and package processes [2].…”
