Semiconductor point contacts can be a useful tool for producingspin-polarized currents in the presence of spin-orbit (SO) interaction. Neithermagnetic fields nor magnetic materials are required. By numerical studies, weshow that (i) the conductance is quantized in units of 2e^2/h unless the SOinteraction is too strong, (ii) the current is spin-polarized in the transversedirection, and (iii) a spin polarization of more than 50% can be realized withexperimentally accessible values of the SO interaction strength. Thespin-polarization ratio is determined by the adiabaticity of the transitionbetween subbands of different spins during the transport through the pointcontacts.Comment: 4 pages, 4 figures; minor changes, published in J.
