Abstract
Abstract
In this talk, we review our recent efforts to implement multiple essential elements for quantum information processing applications using photonics. We use a hybrid integration technique to couple quantum emitters with photonic devices that can efficiently transport, filter, route, and wavelength-tune the emitters.
WF3.2 - WHISPERING-GALLERY-MODE RESONATOR AT EXCEPTIONAL POINTS
Abstract
Abstract
In this talk, I will discuss some interesting phenomena around exceptional points (EPs) in whispering-gallery-mode resonators. Examples including chiral modes and lasing, EP-enhanced sensing, a non-Hermitian phonon laser with linewidth tuned in the vicinity of EPs, and EP-induced transparency and absorption will be introduced.WF3.3 - OPTICALLY PUMPED 1 μm LOW THRESHOLD PHOTONIC CRYSTAL SURFACE EMITTING LASERS GROWN ON GaAs SUBSTRATE

Abstract
Abstract
We report optically pumped 1 μm low threshold GaAs photonic crystal surface emitting lasers. The GaAs photonic crystal is etched on 3-period InGaAs/AlGaAs MQW heterostructure. A laser peak is achieved at 1,006 nm with a linewidth of 0.6 nm at 5 kW/cm2 threshold power density.
WF3.4 - MODE-LOCKING WITH HERMITE-GAUSSIAN MODES
Abstract
Abstract
Stable mode locking and dissipative soliton formation are predicted in a laser cavity with an effective photonic harmonic potential. As all modes starting from the fundamental are involved, the cavity is substantially more compact than a Fabry-Perot resonator with comparable pulsing period.
