Integrating all-optical switching with spintronics. [PDF]

open access: yesNat Commun, 2019
All-optical switching (AOS) of magnetic materials describes the reversal of the magnetization using short (femtosecond) laser pulses, and received extensive attention in the past decade due to its high potential for fast and energy-efficient data writing

Evaluation of the optical switching characteristics of erbium-doped fibres for the development of a fibre Bragg grating sensor interrogator [PDF]

open access: yes, 2014
A polling topology that employs optical switching based on the properties of erbium-doped fibres (EDFs) is used to interrogate an array of FBGs. The properties of the EDF are investigated in its pumped and un-pumped states and the EDFs’ switching ...

Towards High Extinction Ratio in Silicon Thermo-Optic Switches—Unravelling Complexity of Fabrication Variation

open access: yesIEEE Photonics Journal, 2018
$2\times 2$ Mach–Zehnder thermo-optic switches on silicon are found to exhibit huge difference of extinction ratios between the bar and cross port, with the bar port lower by up to 20 dB.
