“…This paper reports on the emission of pulsed nonclassical light from a single QD embedded in a distributed Bragg reflector (DBR) micropillar cavity which is pumped by an electrically driven whispering gallery mode (WGM) microlaser on the same chip. Previous experiments on a similar structure demonstrated p-shell resonant excitation and single QD cavity-quantum electrodynamic (cQED) effects in the weak coupling regime under continuous wave (CW) excitation [27]. In this work, we study the Purcell-enhanced emission in both steady-state and time-resolved (TR) measurements via continuous and pulsed operation of the integrated microlaser.…”

We present a novel compact nanophotonic device consisting of a nonclassical light source excited by a monolithically integrated and electrically driven quantum dot (QD) microlaser. Our device concept is based on self-assembled InAs QDs embedded in micropillar cavities and has many potential applications in the fields of quantum communication and quantum optics-based information processing. Electrically driven micropillars act as whispering gallery mode microlasers operable in both continuous and pulsed mode, with narrow pulse widths of 520 ps and decay constants as low as 160 ps observed. These microlasers are used as on-chip excitation sources to laterally excite individual QDs in nearby micropillars, which in turn act as vertically emitting nonclassical light sources. Our compact solid-state platform utilizes cavity-quantum electrodynamic effects to create antibunched light in continuous and pulsed operation with g (2)C W (0) = 0.76 ± 0.03 and g (2) P u lsed (0) = 0.78 ± 0.11, demonstrating its potential for the generation of triggered single photons in a highly integrated chip.

“…ICRODISK lasers [1] are promising light sources for application in photonic integrated circuits, chemical and biological sensing and imaging [2,3,4]. Following the tendency for the miniaturization in micro-and optoelectronics many research groups focused on reducing diameter (D) of microdisk while retaining high quality factor and low threshold.…”

Lasing characteristics of InAs/InGaAs quantum dot microdisks with diameter varied from 1 to 6 m were studied under optical pumping. The disks were fabricated with standard photolithography and two-step wet etching. We demonstrate room temperature lasing in the 1.29-1.32 m wavelength range (ground-state transition) in microlasers as small as 1 m in diameter. The microlasers demonstrate narrow linewidths (40-60 pm), low thermal impedance (85 о C/mW) and low threshold powers (50-100 W).Index Terms-Microdisk, quantum dots, whispering gallery modes.

“…Our general emission scheme has recently been introduced in the context of full and all-optical control on a single photon's polarization state [15]. It is based on a nondegenerate enhanced two-photon emission [16,17] from the biexciton to the ground state in a commonly available solid-state system, a single semiconductor QD inside an optical microcavity [18][19][20][21][22][23][24][25][26]. As illustrated in Fig.…”

All-optical tailoring of single-photon spectra in a quantum-dot microcavity system

et al. 2016

View full text Add to dashboard Cite

Semiconductor quantum-dot cavity systems are promising sources for solid-state-based on-demand generation of single photons for quantum communication. Commonly, the spectral characteristics of the emitted single photon are fixed by system properties such as electronic transition energies and spectral properties of the cavity. In the present work we study cavity-enhanced single-photon generation from the quantum-dot biexciton through a partly stimulated nondegenerate two-photon emission. We show that frequency and linewidth of the single photon can be fully controlled by the stimulating laser pulse, ultimately allowing for efficient all-optical spectral shaping of the single photon.
