Electro-Thermal Analysis of Oxide-Confined Vertical-Cavity Lasers [PDF]

physica status solidi (a), 2001
The performance of oxide-confined vertical-cavity lasers (VCLs) can be severely limited by current leakage and self-heating. This paper investigates electrical and thermal effects of lateral oxidation on wafer-bonded 1.55 μm VCLs. Measurements are combined with two-dimensional finite-element simulations to analyze internal device physics.

Electro-diffusion in a plasma with two ion species

, 2012
Electric field is a thermodynamic force that can drive collisional inter-ion-species transport in a multicomponent plasma. In an inertial confinement fusion (ICF) capsule, such transport causes fuel ion separation even with a target initially prepared to

Electro-thermal analysis of the superconducting dipole circuit of SIS100

Journal of Physics: Conference Series, 2020
Abstract The heavy ion synchrotron SIS100, the core machine of the new international Facility for Antiproton and Ion Research (FAIR) in Darmstadt, is currently under construction. The 108 superconducting dipole magnets of SIS100 will be powered in series with a cycling rate up to 30kAs−1 which corresponds to 4Ts−1.

Electro-mechano-optical detection of nuclear magnetic resonance

, 2018
Signal reception of nuclear magnetic resonance (NMR) usually relies on electrical amplification of the electromotive force caused by nuclear induction. Here, we report up-conversion of a radio-frequency NMR signal to an optical regime using a high-stress
