Spatial and Polarization Division Multiplexing Harnessing On-Chip Optical Beam Forming
On-chip spatial and polarization multiplexing has emerged as a powerful strategy to boost the data transmission capacity of integrated optical transceivers. State-of-the-art multiplexers require accurate control of the relative phase or the spatial distribution among different guided optical modes, …

Electrically driven nanogap antennas and quantum tunneling regime
The optical and electrical characteristics of electrically-driven nanogap antennas are extremely sensitive to the nanogap region where the fields are tightly confined and electrons and photons can interplay. Upon injecting electrons in the nanogap, a conductance channel opens between …

Sub-Hz closed loop electro-optomechanical oscillator with Gallium phosphide photonic crystal integrated on SoI circuitry
We report on a new approach of a low phase noise electro-optomechanical oscillator directly working in the GHz frequency range. The developed nano-scale oscillator is a one-dimensional photonic crystal made of GaP, heterogeneously integrated on silicon-on-insulator circuitry. Based on …
