Power refers to that phase vortex light beam can be expanded as a series of master screw phase of power approximately equal (changed power is less than 3dB)
The superposition state of vortex devises a kind of phase-plate for generating and having the OAM superposition state of flat power spectrum accordingly.The phase-plate has
Structure is simple, the advantages that can integrating, and can effectively generate the angular momentum superposition state that OAM pattern count is up to tens of ranks.However,
The phase-plate does not have adjustability, once i.e. phase-plate preparation is completed, the OAM superposition state of generation is just determined.This, which does not meet, works as
Demand of the preceding people to high flexible tunable devices.In addition, the phase between the OAM mode for the OAM superposition state that the phase-plate generates

The relative rotation angle θ of the symmetry axis of cylindrical dipole in column 2 and the azimuth of cylindrical dipole position meet relationshipAnd the nested combination (see Fig. 3) of cylindrical dipole array 1 and 2, light field can get phase
Location factorTherefore optical output field becomes (as shown in Figure 4)
Formula (1) can expand into the superposition of series of standards helical phase vortex light, therefore be OAM superposition state light.Its
In N rank be vortexed the OAM mode of N (topological charge values be) relative power (relative to incident optical power Pin=| E0|2) are as follows:
P (N)=| F (N) |2 (2)
For N rank Fourier coefficients.When M takes value appropriate, the power spectrum of the OAM superposition state is opposite there are one
Changed power is less than the flat section of 1dB.The topological charge values of the center OAM mode in the flat section can be moved with the variation of α

Two kinds of complex conjugate forms of formula (1) are respectively corresponded in σ=1 and σ=- 1, the angular momentum spectrum in the case of σ=1 and two kinds of σ=- 1
About the bilateral symmetry of topological charge 0, the then necessarily part point each other of angular momentum spectrum when α ≠ π in the case of σ=1 and two kinds of σ=- 1
From, this causes the present invention to have polarization controllability.Fig. 5 (a) show α=0, the OAM spectrum of OAM superposition state when M=59, and 5
It (b) is α=pi/2, the OAM spectrum of OAM superposition state when M=59；5 (c) be α=0, the OAM spectrum of OAM superposition state when M=80,5

(σ=1) ,+mark curve correspond to the incident light situation (σ=- 1) of right-hand circular polarization.It can be seen that the power spectrum of OAM superposition state is deposited
It is less than the flat section of 1dB in a relative power variation, the OAM pattern count in flat section can achieve tens of ranks, in addition
As α=0, the angular momentum spectrum in the case of σ=1 and two kinds of σ=- 1 is kept completely separate.
