Electron spin polarization induced by linearly polarized light in a (110) GaAs quantum-well waveguide.

چکیده
We report an experimental demonstration of generating electron spin polarization with linearly polarized light in a (110) GaAs quantum well. A detailed frequency-domain pump-probe study shows that the dynamic nuclear spin polarization arising from the oriented electron spins results in a strong dependence of the electron spin splitting on the photon energy and intensity of the linearly polarized excitation laser.

2 7 Ja n 20 05 Photo - induced pure spin currents in quantum wells
As is well known the absorption of circularly polarized light in semiconductors results in optical orientation of electron spins and helicity-dependent electric photocurrent, and the absorption of linearly polarized light is accompanied by optical alignment of electron momenta. Here we show that the absorption of unpolarized light in a quantum well (QW) leads to generation of a pure spin curren...
متن کاملAccuracy of circular polarization as a measure of spin polarization in quantum dot qubits.
A quantum dot spin light emitting diode provides a test of carrier spin injection into a qubit and a means for analyzing carrier spin injection and local spin polarization. Even with 100% spin-polarized carriers the emitted light may be only partially circularly polarized due to the geometry of the dot. We have calculated carrier polarization-dependent optical matrix elements for InAs/GaAs self...
متن کاملSlow light using spin coherence and V-type electromagnetically induced transparency in [110] strained quantum wells
We model the slow-light phenomenon using electromagnetically induced transparency from spin coherence in [110] quantum wells. The long electron-spin lifetime in [110] quantum wells and the strain-induced shift of the light-hole-like excitonic transition energy below those of the heavy-hole-like continuum states can enhance the performance of slow light. The optical anisotropy due to band mixing...
متن کاملSpectroscopic Characterization of III-V Semiconductor Nanomaterials
III-V semiconductor materials form a broad basis for optoelectronic applications, including the broad basis of the telecom industry as well as smaller markets for high-mobility transistors. In a somewhat analogous manner as the traditional silicon logic industry has so heavily depended upon process manufacturing development, optoelectronics often relies instead on materials innovations. This th...
متن کاملSpin-Polarized Electrons
In numerous experiments involving electrons, the ability to manipulate the spin of the electron gives unique additional information. For many years, however, such experiments were extraordinarily rare because of the absence of a good source of spin-polarized electrons. Up to the time this paper appeared, sources of spin-polarized electrons produced electron beams of very low intensity or polari...
