Controlling evanescent waves using silicon photonic all-dielectric metamaterials for dense integration

Nature Communications, 2018
Miniaturization of optical components could give way to dense photonic-integrated circuits. Here, the authors demonstrate the control of evanescent waves using all-dielectric metamaterials and show that they can reduce cross-talk and bending loss, which ...

Programmable Silicon Photonic Integrated Circuits [PDF]

2020 IEEE Photonics Conference (IPC), 2020
Programmable photonic circuits offer a new way to explore photonic chips: instead of hardwiring waveguide connections, one programs a mesh of tunable couplers. This requires electronics and software routines to govern the behavior of the chip, making it possible to rapidly develop new photonic applications.

Hybrid integrated quantum photonic circuits

Nature Photonics, 2020
Recent developments in chip-based photonic quantum circuits has radically impacted quantum information processing. However, it is challenging for monolithic photonic platforms to meet the stringent demands of most quantum applications. Hybrid platforms combining different photonic technologies in a single functional unit have great potential to ...
