Ultralow threshold laser using a single quantum dot and a microsphere cavity
We propose a novel semiconductor microlaser, made by capturing the light emitted from a single InAs/GaAs quantum dot in the whispering-gallery mode of a glass microsphere. We demonstrate that such an arrangement allows the laser threshold condition to be satisfied. The corresponding threshold current should be several orders of magnitude lower than is currently possible in semiconductor lasers....
متن کاملDual Wavelength Passive and Hybrid Mode-Locking of a 10GHz Quantum Dot Laser Diode at 1.5μm
We report on stable dual-wavelength operation in passive and hybrid mode-locking of a 10GHz two-section InAs/InP(100) quantum dot laser diode operating at 1.5μm. The range of stable passive mode-locking, the locking range of hybrid mode-locking and detailed measurements of the phase modulation in the output pulses will be presented. Keywordsmode-locked laser diode; quantum dot; hybrid mode-lock...
متن کاملCavity QED with quantum dots in semiconductor microcavities
Cavity quantum electrodynamic (QED) effects are studied in semiconductor microcavities embedded with InGaAs quantum dots. Evidence of weak coupling in the form of lifetime enhancement (the Purcell effect) and inhibition is found in both oxide-apertured micropillars and photonic crystals. In addition, high-efficiency, low-threshold lasing is observed in the photonic crystal cavities where only 2...
متن کاملWhispering-gallery mode microdisk lasers
A new microlaser design based on the high-reflectivity whispering-gallery modes around the edge of a thin semiconductor microdisk is described and initial experimental results are presented. Optical confinement within the thin disk plane results in a microresonator with potential for single-mode, ultralow threshold lasers. Initial experiments use selective etching techniques in the InP/InGaAsP ...
متن کامل(hbcu/mi) Ultralow Noise Monolithic Quantum Dot Photonic Oscillators
three different nanostructured semiconductor lasers were studied – the quantum dot passively mode-locked laser, the dual-mode quantum dot laser and the optically-injected quantum dot distributed feedback laser. The key milestones achieved were: 1) the use of optical feedback to reduce the timing jitter of the pulsed lasers from 295 fs/cycle to 32 fs/cycle, 2) experimental determination of the o...
