Studies of particle and atom manipulation using free space light beams and photonic crystal fibres

, 2009
Light can exert optical forces on matter. In the macroscopic world these forces are minuscule, but on the microscopic or atomic scale, these forces are large enough to trap and manipulate particles.

Enhancing responsivity of silicon PIN photodiodes at 1064 nm via light trapping and geometry optimization: a simulation study

Frontiers in Physics
Nd:YAG laser light detection at 1064 nm is widely used in applications requiring high-performance photodiodes to measure low light intensities. This study investigates the impact of light trapping and geometric variations on the responsivity of silicon ...

Light Trapping above the Light Cone in One-Dimensional Arrays of Dielectric Spheres

Applied Sciences, 2017
We demonstrate bound states in the radiation continuum (BSC) in a linear periodic array of dielectric spheres in air above the light cone. We classify the BSCs by orbital angular momentum m = 0,±1,±2 according to the rotational symmetry of the array ...

Solution‐Processed Two‐Dimensional Indium Oxide on Sodium‐Embedded Alumina for Reconfigurable Optoelectronic Synaptic Transistors

Advanced Functional Materials, EarlyView.
Wafer‐scale two‐dimensioanl In2Se3 oxidized into InOx on sodium‐embedded beta‐alumina enables multifunctional reconfigurable electronics. Sodium ions accumulate within distinct spatial distribution under drain‐controlle and gate‐controlled operation. Drain‐control operation gives controllability of ultraviolet‐driven optoelectronic synaptic conductance

Strongly enhanced light trapping in a two-dimensional silicon nanowire random fractal array

Light: Science & Applications, 2016
We report on the unconventional optical properties exhibited by a two-dimensional array of thin Si nanowires arranged in a random fractal geometry and fabricated using an inexpensive, fast and maskless process compatible with Si technology. The structure

Transfer Printing and Reconfiguration of Soft Electronics Using Digital Microfluidics and Laser Machining

Advanced Functional Materials, EarlyView.
This paper presents a digital microfluidics‐based technique for transferring and reconfiguring soft nanomembranes. Laser‐machined nanothin membranes are picked up, transported, and aligned via tailored surface tension and the actuation of water droplets, enabling the development of flexible electronics, the integration of functional materials on 3D ...

Faraday Rotation of Pulsed and Continuous-wave Light in Atomic Vapour [PDF]

, 2011
The absorptive and dispersive properties of a Doppler-broadened vapour of rubidium atoms is investigated. A detailed model of the atom-light interaction is developed and found to be in excellent agreement with experiment in the regime where the ...
