A resonant metasurface with high quality factor can not only localize light at the nanoscale but also manipulate the far-field radiation. In this work, we experimentally demonstrate an active Fano-...

We demonstrate the use of a photonic crystal (PhC) structure to improve the performance of a germanium avalanche photodetector (APD) by simultaneously manipulating the distribution of the optical and electric fields. The PhC is fabricated at the top

We have designed and realized a high-efficiency normal-incidence germanium photodetector combining with resonant all-dielectric metasurface. With an intrinsic layer thickness of 350 nm, a high external quantum efficiency of 54% is achieved at 1550 nm

A silicon light emitter operating in 1–1.6 μm wavelength range is realized by growth of strained SiGe layer on microring-patterned silicon-on-insulator substrates by molecular beam epitaxy. Strong resonance peaks are observed in the microphotolumi

All-dielectric metamaterials offer great flexibility for controlling light–matter interaction, owing to their strong electric and magnetic resonances with negligible loss at wavelengths above the material bandgap. Here, we propose an all-dielectric
