Fine-Resolution Silicon Photonic Wavelength-Selective Switch Using Hybrid Multimode Racetrack Resonators

Lucas M. Cohen, Saleha Fatema, Vivek V. Wankhade +5

In this work, we describe a procedure for synthesizing racetrack resonators with large quality factors and apply it to realize a multi-channel wavelength-selective switch (WSS) on…

New horizons in near-zero refractive index photonics and hyperbolic metamaterials

Michaël Lobet, Nathaniel Kinsey, Iñigo Liberal +7

The engineering of the spatial and temporal properties of both the electric permittivity and the refractive index of materials is at the core of photonics. When vanishing to zero,…
