Meta-Optics Triplet for Zoom Imaging at Mid-Wave Infrared
Anna Wirth-Singh, Arturo Martin Jimenez, Minho Choi +5
Lenses with dynamic focal length, also called zoom functionality, enable a variety of applications related to imaging and sensing. The traditional approach of stacking refractive l…
Wide Field of View Large Aperture Meta-Doublet Eyepiece
Anna Wirth-Singh, Johannes E. Fröch, Fan Yang +10
Wide field of view and light weight optics are critical for advanced eyewear, with applications in augmented/virtual reality and night vision. Conventional refractive lenses are of…
Coupling Spin Defects in a Layered Material to Nanoscale Plasmonic Cavities
Noah Mendelson, Ritika Ritika, Mehran Kianinia +11
Spin defects in hexagonal boron nitride, and specifically the negatively charged boron vacancy (VB) centres, are emerging candidates for quantum sensing. However, the VB defects su…
Coupling spin defects in hexagonal boron nitride to monolithic bullseye cavities
Johannes E. Fröch, Lesley Spencer, Mehran Kianinia +6
Color centers in hexagonal boron nitride (hBN) are becoming an increasingly important building block for quantum photonic applications. Herein, we demonstrate the efficient couplin…
Fabrication of photonic resonators in bulk 4H-SiC
Otto Cranwell Schaeper, Johannes E. Fröch, Sejeong Kim +4
The design and engineering of photonic architectures, suitable to enhance, collect and guide light on chip is needed for applications in quantum photonics and quantum optomechanics…
Second-harmonic generation in multilayer hexagonal boron nitride flakes
Sejeong Kim, Johannes E. Fröch, Augustine Gardner +3
We report second-harmonic generation (SHG) from thick hexagonal boron nitride (hBN) flakes with approximately 109-111 layers. The resulting effective second-order susceptibility is…
