• Purcell Enhancement of a Single Silicon Carbide Color Center with Coherent Spin Control

  Nano Letters · 2020-03-25 · 146 citations

  articleOpen access

  Silicon carbide has recently been developed as a platform for optically addressable spin defects. In particular, the neutral divacancy in the 4H polytype displays an optically addressable spin-1 ground state and near-infrared optical emission. Here, we present the Purcell enhancement of a single neutral divacancy coupled to a photonic crystal cavity. We utilize a combination of nanolithographic techniques and a dopant-selective photoelectrochemical etch to produce suspended cavities with quality…

• Development of Quantum Interconnects (QuICs) for Next-Generation Information Technologies

  PRX Quantum · 2021 · 82 citations

  Just as classical information technology rests on a foundation built of interconnected information-processing systems, quantum information technology (QIT) must do the same. A critical component of such systems is the interconnect, a device or process that allows transfer of information between disparate physical media, for example, semiconductor electronics, individual atoms, light pulses in optical fiber, or microwave fields. While interconnects have been well engineered for decades in the rea…

• Three-Dimensional Reconfigurable Optical Singularities in Bilayer Photonic Crystals

  Physical Review Letters · 2024-02-16 · 70 citations

  article

  Metasurfaces and photonic crystals have revolutionized classical and quantum manipulation of light and opened the door to studying various optical singularities related to phases and polarization states. However, traditional nanophotonic devices lack reconfigurability, hindering the dynamic switching and optimization of optical singularities. This paper delves into the underexplored concept of tunable bilayer photonic crystals (BPhCs), which offer rich interlayer coupling effects. Utilizing sili…

• Electrical manipulation of telecom color centers in silicon

  Nature Communications · 2024-06-03 · 22 citations

  articleOpen accessSenior author

  Silicon color centers have recently emerged as promising candidates for commercial quantum technology, yet their interaction with electric fields has yet to be investigated. In this paper, we demonstrate electrical manipulation of telecom silicon color centers by implementing novel lateral electrical diodes with an integrated G center ensemble in a commercial silicon on insulator wafer. The ensemble optical response is characterized under application of a reverse-biased DC electric field, observ…
