High speed InAs electron avalanche photodiodes overcome the conventional gain-bandwidth product limit [PDF]

open access: yes, 2011
High bandwidth, uncooled, Indium Arsenide (InAs) electron avalanche photodiodes (e-APDs) with unique and highly desirable characteristics are reported. The e-APDs exhibit a 3dB bandwidth of 3.5 GHz which, unlike that of conventional APDs, is shown not to

Fabricating waveguide Bragg gratings (WBGs) in bulk materials using ultrashort laser pulses

open access: yesNanophotonics, 2017
Optical waveguide Bragg gratings (WBGs) can be created in transparent materials using femtosecond laser pulses. The technique is conducted without the need for lithography, ion-beam fabrication methods, or clean room facilities.

A chip-integrated coherent photonic-phononic memory

open access: yesNature Communications, 2017
Optical storage implementations based on optomechanical resonator are limited to one wavelength. Here, exploiting stimulated Brillouin scattering, the authors demonstrate a coherent optical memory based on a planar integrated waveguide, which can operate

Magnetic hyperbolic optical metamaterials

open access: yesNature Communications, 2016
The ability to control both electric and magnetic dispersion of light allows a novel type of hyperbolic material with impedance matched to air. Here, the authors show experimentally a topological transition between elliptic and magnetic hyperbolic ...

Effectiveness of adjusted bandwidth knowledge of results in motor learning

open access: yesCogent Psychology, 2022
Introduction: Knowledge of results (KR) is a method of augmented feedback where frequency or timing varies depending on the individual’s performance. In previous studies, bandwidth (BW) KR was not established according to the individual’s performance ...
