Small signal modulation characteristics of red-emitting (λ = 610 nm) III-nitride nanowire array lasers on (001) silicon

“…Through the measurement of the laser linewidth enhancement factor, a, we show that the InGaN disks in the nanowires behave as quantum dots electrically, which may explain the low threshold current density and high temperature stability of these devices, which are comparable with self-assembled quantum dot lasers. [19][20][21][22] Through modulation experiments, we derive a differential gain of 3.1 Â 10 À17 cm 2 and measure a maximum modulation bandwidth of 3.1 GHz and chirp less than 1 Å .…”

III-Nitride-Based Quantum Dots and Their Optoelectronic Applications

“…Although growth and optical properties of InGaN QDs are intensively studied currently [22,39,40], there has been only very few reports on lasing from InGaN-based QDs, especially under an electrical injection. Nevertheless, an electrically injected InGaN/GaN QD laser has been reported recently [41]. As shown in Fig.…”

Tight‐binding model for the electronic and optical properties of nitride‐based quantum dots

“…As shown theoretically [20,21], nitride-based QDs exhibit for several reasons much smaller built-in fields than QW structures of the same height. Based on this idea, QD-based LEDs [22] and laser structures [23] operating in the green spectral region have been demonstrated recently and have shown superior performance than their QW-based counterparts.…”
