All matter at finite temperatures emits electromagnetic radiation due to the thermally induced motion of particles and quasiparticles. Dynamic control this could enable design novel infrared sources; however, spectral characteristics radiated power are dictated by energy density emissivity, which ordinarily fixed properties material temperature. Here we experimentally demonstrate tunable electronic blackbody emission from graphene plasmonic resonators on a silicon nitride substrate. It is...

Graphene nanostructures that support surface plasmons have been utilized to create a variety of dynamically tunable light modulators, motivated by theoretical predictions the potential for unity absorption in resonantly-excited monolayer graphene sheets. Until now, generally low efficiencies resonant absorbers limited mismatch between free-space photons and plasmons.

Abstract Nitrogen vacancy centers in diamond provide a spin-based qubit system with long coherence time even at room temperature, making them suitable ambient-condition quantum sensors for quantities including electromagnetic fields, and rotation. The optically addressable level structures of NV spins allow transduction spin information onto light-field intensity. sub-optimal readout fidelity conventional fluorescence measurement remains significant drawback room-temperature ensemble...

Abstract The large scale control over thousands of quantum emitters desired by network technology is limited the power consumption and cross-talk inherent in current microwave techniques. Here we propose a repeater architecture based on densely-packed diamond color centers (CCs) programmable electrode array, with gates driven electric or strain fields. This ‘field spin array’ (FPSA) enables high-speed individual CCs low dissipation. Integrated slow-light waveguide for efficient optical...

Nitrogen vacancy (NV) centers in diamond have emerged as a leading quantum sensor platform, combining exceptional sensitivity with nanoscale spatial resolution by optically detected magnetic resonance (ODMR). Because fluorescence-based ODMR techniques are limited low photon collection efficiency and modulation contrast, there has been growing interest infrared (IR)-absorption-based readout of the NV singlet state transition. IR can improve contrast efficiency, but it thus far to long-path...

The decay dynamics of excited carriers in graphene have attracted wide scientific attention, as its gapless Dirac electronic band structure opens up relaxation channels that are not allowed conventional bulk materials. We report bright mid-infrared emission from laser-pumped graphene, originating a previously unobserved channel: hot plasmon emission. observed Fermi-level dependence radiation rules out all possible Planckian light mechanisms. Calculations for our experimental conditions...
