Optical junction box rectification
In optical rectification, electrons must keep up with the rapid oscillations of an illuminating optical field and harness the nonlinearities of a tunneling contact to produce the desired DC field. This is because the optical nonlinearity can not only generate frequency components of the nonlinear polarization related to the sums and differences of the involved optical frequencies (→ sum and difference frequency generation), but also a component the frequency of which is the difference of. Optical rectification is a nonlinear optical process where an intense light beam interacts with a nonlinear optical material, generating a static electric field or a low-frequency electromagnetic field. This process is. Here, we measure the photon-assisted current in a planar tunnel junction under infrared illumination. To address the microscopic mechanism at the origin of the optical rectification, we.
