Light emission from vertical-microcavity quantum dot laser structures

Switch-on dynamics of nanocavity laser devices

“…Recently, semiconductor active regions coupled with nanoscale optical resonator schemes have opened an additional level of miniaturization and facilitated the implementation of photonic integrated circuits. The advent of photonic crystals allows to fabricate high-quality cavities, [1][2][3][4] which opens a multitude of possibilities for guiding and modifying the emission properties via Purcell enhancement of emission rates, 4 and also allows to directly integrate nanocavities with optical waveguides. For such photonic circuits, nanolasers are an important ingredient.…”

Theory of nanolaser devices: Rate equation analysis versus microscopic theory

“…They are considered as gain material for next generation optoelectronic devices and for fundamental studies of light-matter interaction. [3][4][5] The advent of photonic crystals allows one to combine QDs with high-quality cavities, [6][7][8][9] which opens a multitude of possibilities for guiding and modifying the emission properties of QD-based devices via Purcell enhancement of emission rates. 9 Therefore, the laser dynamics of nanocavity-based laser devices has been a much debated topic in recent years (see, e.g., Refs.…”

Dependence of the modulation response of quantum dot based nanocavity devices on the number of emitters

“…The advent of photonic crystals allows to combine QDs with high-quality cavities [6,7,8,9], which opens a multitude of possibilities for guiding and modifying the emission properties of QD-based devices via the Purcell factor [9]. Therefore, the laser dynamics of nano-cavity based laser devices has been a much debated topic in recent years, see e.g.…”
