Paper Abstract
Optical micromanipulation offers a unique insight into light-matter interaction at the mesoscopic level within
the classical framework. The optical forces used in this process originate from the conservation of energy and
momentum during an optical interaction. They can be determined through the use of the electromagnetic
energy-momentum tensor which describes the flux of momentum and energy. However, can we use this direct
opto-mechanical interaction to further our understanding of the classical nature of photons? In this paper,
I generalize the momentum energy tensor and determine its eigenmodes for a given scattering object. These
eigenmodes decompose the classical electromagnetic field into modes that have formally similar properties to
those associated with photons i.e. modes with uniquely defined energy, momentum and polarization. This
classical interpretation of photons is put forward and discussed in the context of small scattering particles.
When a single photon is scattered from an object, transferring its momentum, is its final state one of the
momentum energy eigenmodes? Potential experiments are discussed that could confirm this assumption in
the case of single photon optical trapping and verify the "classical" nature of the photon.
