Semiconductor-based Geometrical Quantum Gates [PDF]
, 2002 We propose an implementation scheme for holonomic, i.e., geometrical, quantum information processing based on semiconductor nanostructures. Our quantum hardware consists of coupled semiconductor macroatoms addressed/controlled by ultrafast multicolor ...

Integrated electroplated heat spreaders for high power semiconductor lasers [PDF]
, 2008 Thermal management of high power semiconductor lasers is challenging due to the low thermal conductivity of the laser substrate and the active device layers. In this work, we demonstrate the use of a microfabricated laser test device to study the thermal

Bifurcation analysis of a semiconductor laser with filtered optical feedback [PDF]
, 2006 We study the dynamics and bifurcations of a semiconductor laser with delayed filtered optical feedback, where a part of the output of the laser reenters after spectral filtering. This type of coherent optical feedback is more challenging than the case of

Laser-controlled local magnetic field with semiconductor quantum rings [PDF]
, 2005 We analize theoretically the dynamics of N electrons localized in a semiconductor quantum ring under a train of phase-locked infrared laser pulses. The pulse sequence is designed to control the total angular momentum of the electrons.

Magnon activation by hot electrons via non-quasiparticle states [PDF]
, 2017 We consider the situation when a femtosecond laser pulse creates a hot electron state in half-metallic ferromagnet (e. g. ferromagnetic semiconductor) on a picosecond timescale but do not act directly on localized spin system. We show that the energy and

Laser Radiation Induces Growth and Lipid Accumulation in the Seawater Microalga Chlorella pacifica
Energies, 2017 The impacts of laser radiation (Nd: YAG laser, 1064 nm at 800 mW, He–Ne laser 808 nm at 6 W, semiconductor laser 632.8 nm at 40 mW) on growth and lipid accumulation of Chlorella pacifica were investigated in this study.

Special Issue “Semiconductor Laser Dynamics: Fundamentals and Applications”
Photonics, 2020 With the advent of integrated photonics, a crucial role is played by semiconductor diode lasers (SDLs) as coherent light sources. Old paradigms of semiconductor laser dynamics, like optical injection, external feedback and the coupling of lasers ...
