  text: Spin-polarized electron beam sources enable studies of spin-dependent electric
    and magnetic effects at the nanoscale. We propose a method of creating spin-polarized
    electrons on an integrated photonics chip by laser-driven nanophotonic fields.
    A two-stage interaction separated by a free-space drift length is proposed, where
    the first stage and drift length introduces spin-dependent characteristics into
    the probability distribution of the electron wave function. The second stage uses
    an adjusted optical near field to rotate the spin states utilizing the spin-dependent
    wave-packet distribution to produce electrons with high ensemble average spin
    expectation values. This platform provides an integrated and compact method to
    generate spin-polarized electrons, implementable with millimeter scale chips and
    tabletop lasers.
