“…In the recent years, InGaN has become probably the most intensively studied among all the material systems used for QW lasers. Although InGaN can emit effectively light in red, green, blue and ultraviolet, recently most InGaN applications focused on the blue [1][2][3][4][5][6] and green [5][6][7][8] spectral ranges (some of them [5][6] can operate, with composition and structure variations, both in blue and green spectra) and also some in the deep violet [9]. In this paper we present simulations of the main characteristics of an InGaN QW laser that operates in the blue spectrum, at the wavelength of 462 nm.…”

For almost three decades, InGaN (indium gallium nitride) quantum well (QW) lasers have received a lot of interest from the scientific research community. Recently, this material system has become probably the most intensively studied among all the material systems used for quantum well lasers. We simulated the characteristics of an In 0.02 Ga 0.98 N QW laser at a wavelength of 462 nm, particularly the carrier concentration distribution, the potential distribution, the energy band diagram, the wave intensity profile, the I-V and L-I characteristics, the background absorption, the radiative, Auger, Shockley-Read-Hall (SRH) and stimulated recombination, threshold current density, slope efficiency and external differential quantum efficiency, to gain an almost exhaustive general view of the performance characteristics of this structure, constituting in a more useful reference for applications than previous incomplete data gathered for this structure.
