Coupling an electron spin in a semiconductor quantum dot to an optical nano-cavity
Arka Majumdar, Per Kaer, Michal Bajcsy +4
We propose a scheme to efficiently couple a single quantum dot electron spin to an optical nano-cavity, which enables us to simultaneously benefit from a cavity as an efficient pho…
Electrical Control of Silicon Photonic Crystal Cavity by Graphene
Arka Majumdar, Jonghwan Kim, Jelena Vuckovic +1
Efficient conversion of electrical signal to optical signal in nano-photonics enables solid state integration of electronics and photonics. Combination of graphene with photonic cr…
Quasiresonant Excitation of InP/InGaP Quantum Dots Using Second Harmonic Generated in a Photonic Crystal Cavity
Sonia Buckley, Kelley Rivoire, Fariba Hatami +1
Indistinguishable single photons are necessary for quantum information processing applications. Resonant or quasiresonant excitation of single quantum dots provides greater single…
Engineered Quantum Dot Single Photon Sources
Sonia Buckley, Kelley Rivoire, Jelena Vuckovic
Fast, high efficiency, and low error single photon sources are required for implementation of a number of quantum information processing applications. The fastest triggered single…
Design and analysis of photonic crystal coupled cavity arrays for quantum simulation
Arka Majumdar, Armand Rundquist, Michal Bajcsy +3
We performed an experimental study of coupled optical cavity arrays in a photonic crystal platform. We find that the coupling between the cavities is significantly larger than the…
Objective-First Nanophotonic Design
Jesse Lu, Jelena Vuckovic
We introduce an "objective-first" strategy for designing nanophotonic devices, and we demonstrate the design of nanophotonic coupler, cloak, and mimic devices.
A photonic crystal cavity-optical fiber tip nanoparticle sensor for biomedical applications
Gary Shambat, Sri Rajasekhar Kothapalli, Aman Khurana +8
We present a sensor capable of detecting solution-based nanoparticles using an optical fiber tip functionalized with a photonic crystal cavity. When sensor tips are retracted from…
Photoluminescence from In0.5Ga0.5As/GaP quantum dots coupled to photonic crystal cavities
Kelley Rivoire, Sonia Buckley, Yuncheng Song +2
We demonstrate room temperature visible wavelength photoluminescence from In0.5Ga0.5As quantum dots embedded in a GaP membrane. Time-resolved above band photoluminescence measureme…
