We review epitaxial formation, basic properties, and device applications of a novel type of
nanostructures of mixed (0D/2D) dimensionality that we refer to as quantum well-dots …

Technological progress makes it possible to significantly reduce the size of semiconductor
laser emitters to microscales and sizes commensurate with the emission wavelength …

Large-area lasers are practical for generating high output powers. However, this often
comes at the expense of lower beam quality due to the introduction of higher-order modes …

We study material gain of a novel type of quantum heterostructures of mixed (0D/2D)
dimensionality referred to as quantum well-dots (QWDs). To evaluate the material gain in a …

High-power high-brightness super large optical cavity laser diodes with an optimized
epitaxial structure are investigated at the wavelength of 980 nm range. The thicknesses of P …

Semiconductor lasers have developed rapidly with the steady growth of the global laser
market. The use of semiconductor laser diodes is currently considered to be the most …

The considerations in the epitaxial and longitudinal design of a supper-large-optical-cavity
structure di⁃ ode laser in the 976-nm band are numerically studied and presented here …

Thermal resistance of diode lasers with different waveguide designs has been investigated.
Coupled large optical cavity (CLOC) design allows reducing internal loss and …

We report recent developments on 980-nm single-transverse-mode ridge-waveguide (RW)
lasers with high efficiency and low-vertical divergence. RW lasers fabricated with 7-μm-wide …

In this paper, a microstructured laser with modulated periodic microstructures for beam
control is proposed for the first time. Lasers using modulated periodic microstructures can …
