III-nitride laser diodes (LDs) are an interesting light source for solid-state lighting (SSL). Modelling of LDs is performed to reveal the potential advantages over traditionally used light-emitting diodes (LEDs). The first, and most notable, advanta

Solid-state lighting (SSL) is now the most efficient source of high color quality white light ever created. Nevertheless, the blue InGaN light-emitting diodes (LEDs) that are the light engine of SSL still have significant performance limitations. For

In this paper, we discuss experimental results and the potential for improvement of blue and green laser diode (LD) performance by using semipolar substrates. We show that the InGaN quantum well (QW) grown on a semipolar plane allows higher character

We studied experimentally and theoretically the substrate-orientation impact on carrier transport and capture in InGaN multiple quantum well (MQW) laser diodes (LDs) with emission in the aquamarine-green spectral range. A new simulation approach was

Using varied stripe length method we systematically studied optical gain properties of blue-green 3 nm InGaN QWs grown on c-plane and (11-22) semipolar substrates. We determined that for such structures when the product of modal net gain at peak and

Technologies for artificial lighting, as illustrated on the left side of Fig. 2.1, have made tremendous progress over the centuries: from fire, with an efficiency of about a tenth of a percent; to incandescent lamps, with an efficiency of about 4 %;

During recent years, several research groups have demonstrated a steady progress in increasing InGaN quantum well (QW) laser emission wavelength [1–5], however the threshold current (Fig. 1) and wall plug efficiency (WPE) are still worse than those

We demonstrate >400 h continuous-wave operation with 50% output power degradation for InAlGaN ridge laser diodes with InGaN waveguide relaxed via interfacial misfit dislocations. The lasers with emission wavelength of 503 nm were grown on free-standi

We studied optical absorption of Mg-doped AlInGaN layers using excitation-position dependent and polarization resolved photoluminescence from the slab-waveguide edge of a laser structure. The major absorption in the Mg-doped layers was found only whe
