“…It is worth emphasizing that this formula does not signify any physical displacement in the x-direction; the directly corresponding diagrammatic representation is a plot of the electric field magnitude E0 cos kz, not a distance in z: the ordinate units in SI are V m -1 , not m. Any inference that there is indeed a physical oscillation in the x-direction, weaving back and forth across the z-axis, can lead to unphysical speculations. 25 , respectively, at a position r. 26 In this connection, an optical vortex may be considered as light with a helically formed wavefront. Visually compelling as they may appear, the multi-colored helical surfaces often used to represent optical vortices are mostly misleading -especially where phase is depicted with color-coding.…”

The development of optical modes with intrinsic structure has significantly redirected attention to the established concept and fundamental physics of the photon. In particular, to accommodate the modal structure of beams with transverse structure, two aspects of conventional representation invite special modification: the mathematical formulations, and figurative depictions. Reappraisals of the former highlight known deficiencies in simple plane wave mode expansions, at the price of associating the properties of individual quanta with macroscopic beam parameters wrought by the physical optics. Experimental proofs that such features do indeed reside in individual photons lead to conceptual problems, yet it is clear that alternative viewpoints engender still deeper difficulties. Such quandaries are also evident in the variety of diagrammatic representations used for structured radiation. Though such depictions cannot ever adequately represent the quantum physics, their incautious use can become seriously misleading, misrepresenting the underlying mathematics and supporting wrong conclusions. This analysis aims to expose and underscore some issues that invite closer attention.

“…However, there are unfinished works in that spiraling photon model until now. In the early works 6,7 , only the parameter equations of a spiraling photon were given. The number of the oscillations that the photon experienced per second is the frequency ν of the light.…”

“…We have no reason to suppose that the present concepts represent an ultimate description 2 . Based on Einstein's idea of the photon, Hongrui Li has proposed a new classical photon model 6,7 , in which the photon has energy E=hν spiraling forward. Using this new model either wave property or particle property of light can be well explained.…”

Based no the classical spiraling photon model proposed by Hongrui Li, the laws of reflection, refraction of a single photon can be derived. Moreover, the polarization, total reflection, evanescent wave and Goos-Hanchen shift of a single photon can be elucidated. However, this photon model is still unfinished. Especially, the spiraling diameter of a photon is not definite. In this paper, the continuous research works on this new theory are reported. According to the facts that the diffraction limit of light and the smallest diameter of the focal spot of lenses are all equal to the wavelength λ of the light, we can get that the spiraling diameter of a photon equals to the wavelength λ, so we gain that the angle between the linear velocity of the spiraling photon υ and the component of the linear velocity in the forward direction υ b is 45°, and the energy of a classical spiraling photon E = (1/2)mυ 2 = (1/2)m2c 2 = mc 2 . This coincides with Einstein's mass-energy relation. While it is obtained that the velocity of the evanescent wave in the vacuum is slower than the velocity of light in glass in straight line. In such a way, the optical fiber can slow the light down. In addition, the force analysis of a single photon in optical tweezers system is discussed. And the reason that the laser beam can capture the particle slightly downstream from the focal point can be explained.

“…38 The photon does not travel under the laws of Newtonian particle mechanics, along a track such as might trace out a helix in the case of circular polarizations, for example-nor should the oscillations of an electric field pointing in any particular spatial direction be regarded as a physical displacement in that spatial dimension. Correct representations can be found in standard literature such as the well-known texts by Craig and Thirunamachandran,39 or the more recent one by Duarte.…”

Abstract. The centrality of the photon concept in modern physics is strongly evident in wide spheres of photonics and nanophotonics. Despite the resilience and persistence of earlier classical representations, there are numerous optical features and phenomena that only truly photon-based descriptions of theory can properly address. It is crucial to cast theory in terms of observables, and in this respect the quantum theory of light engages most directly and pragmatically with experiment. No other theory adequately reconciles the discreteness in energy of optical quanta, with their characteristic quantum mechanical delocalization in space. Examples of the distinctiveness of a photonic representation are to be found in nonclassical optical correlations; intensity fluctuations and phase; polarization, spin, and information content; measures of optical chirality; near-field interactions; and plasmonics. Increasingly, links between these fundamental properties and features are proving significant in the context of nanoscale interactions. Yet, even as new technologies are being built on the framework of modern photonics, a number of difficult questions surrounding the nature of the photon still remain. Both in its flourishing applications and in matters of fundamental entity, the photon is still a subject very much at the heart of current research. © The Authors.
