Neuromorphic Light‐Responsive Organic Matter for in Materia Reservoir Computing

Advanced Materials, EarlyView.
In this work we show that light‐responsive adaptive organic matter can store and process information at the matter level, and emulate neuromorphic functionalities such as short term memory, long term memory and visual memory. Besides demonstrating that material dynamics can be exploited for spatio‐temporal event detection and motion perception, we show

Temperature Dependence of a Sub-wavelength Compact Graphene Plasmon-Slot Modulator

, 2017
We investigate a plasmonic electro-optic modulator with an extinction ratio exceeding 1 dB/um by engineering the optical mode to be in-plane with the graphene layer, and show how lowering the operating temperature enables steeper switching.

Low-Power Operation in a Silicon Switch Based on an Asymmetric Mach–Zehnder Interferometer

IEEE Photonics Journal, 2015
Mach-Zehnder interferometer (MZI) structures are widely used as optical switches in photonic integrated circuits. However, power consumption is still the key parameter to make such devices practical in the silicon platform, particularly for those based ...

High‐Performance Phototransistor Based on a 2D Polybenzimidazole Polymer

Advanced Materials, EarlyView.
A crystalline 2D polybenzimidazole polymer (2DPBI), incorporating a porphyrin‐based π‐system linked via 1,3‐diazole units, is synthesized on the water surface over large areas. The 2DPBI thin‐film exhibits high charge carrier mobility (≈240 cm2 V−1 s−1, measured by terahertz spectroscopy), strong photoresponse, and band‐like transport, enabling ...

Brick-Based Silicon Optomechanical Cavity Sensor for Nanoparticles Mass Detection [PDF]

EPJ Web of Conferences
A novel design for an optomechanical cavity consisting of a series of rectangular silicon nanobricks, with each brick acting as an independent mechanical resonator but all coupled to a same optical field, is proposed, and numerically demonstrated.
