Abstract
Harnessing linear and angular momenta of light is
one of the cornerstones in modern optics and has found tremendous
applications in optical circuits, particle manipulation, metrology,
quantum information processing, etc. Emerging theoretical protocols
and experimental explorations have created a surge of interest in
light lateral momenta and forces, which are perpendicular to the light
wave propagation direction. However, there is yet a lack of a
comprehensive and holistic overview of transverse momenta (both linear
and angular) as well as of optical lateral forces (OLFs). In this
article, we first review the most recent transverse momenta including
the transverse spin angular momentum, optical skyrmions, as well as
lateral momenta from directional side scattering, spin–orbit
interaction, and surface plasmon polaritons. Since optical forces
result from the momentum exchange between light and matter, the
transverse momentum consequently gives rise to intriguing OLFs, which
is the second topic of this article. Additional non-trivial lateral
forces that combine optics with other effects from thermodynamics,
electricity, and microfluidics, are also discussed. It should be
emphasized that these momenta and forces ubiquitously exist in a broad
range of optical phenomena and have often been neglected due to their
unpredicted underlying physics and shortage of experimental means,
especially prior to the last
decade.
