Description

Non-destructive vortex light field beam splitting device
Technical Field
The invention relates to the technical fields of laser technology, nonlinear optics and atomic physics, in particular to a nondestructive vortex light field beam splitting device.
Background
The full degrees of freedom of light include frequency, intensity, polarization, and Orbital Angular Momentum (OAM). The singularity of the intensity and phase distribution of OAM carrier beams has stimulated many exciting applications such as optical steering and trapping, high precision optical metrology, and quantum information processing. Mutually orthogonal OAM modes offer the possibility of spatial mode multiplexing for high capacity classical optical communication. The infinite dimension of the OAM mode enables dense coding and coordinate-independent quantum key distribution to become more promising. For various applications based on multiple OAM modes, it is important to efficiently identify and separate the different OAM modes. In the prior invention, there are many ways to achieve this goal. For example, a holographic grating and a single mode fiber can be used as a mode detector for a specific OAM mode, where the mode detector is a projector, we must use N projection measurements to measure N OAM modes. One disadvantage of this method is that the original state is completely destroyed after measurement and is inefficient. Therefore, the method for effectively identifying the light beams with different Orbital Angular Momentum (OAM) has important significance for large-capacity optical communication, quantum information processing and other applications.
Disclosure of Invention
In order to reduce driving equipment and improve the utilization rate of space, the invention provides a nondestructive vortex optical field beam splitting device. The invention adopts the following technical scheme:
a nondestructive vortex light field beam splitting device comprises an annular cavity mode selection module, wherein the annular cavity mode selection module comprises an input coupling mirror, a first dove prism, a second dove prism, a scanning lock cavity assembly, a concave mirror and an output coupling mirror, the input coupling mirror is used for forming an annular cavity, an input light beam is partially reflected and partially transmitted through the input coupling mirror, an L G light beam transmitted by the input coupling mirror sequentially passes through the first dove prism, the second dove prism, the scanning lock cavity assembly, the concave mirror and the output coupling mirror, the output coupling mirror reflects and transmits part of light, and a reflected L G light beam is also partially reflected and partially transmitted after entering the input coupling mirror.
Specifically, the scanning lock cavity assembly comprises a plane mirror and a piezoelectric sensor, wherein the piezoelectric sensor is arranged on the plane mirror.
Specifically, the laser device further comprises a light beam generation module, wherein the light beam generation module comprises a laser, a phase modulation component and a lens component, the laser is sequentially arranged on the light path, the phase modulation component is used for enabling a Gaussian beam output by the laser to be added with a relative phase, and the lens component is used for carrying out mode matching on the Laguerre Gaussian beam carrying orbital angular momentum and the annular cavity.
In particular, the phase modulating component is a spatial light modulator or a vortex phase plate.
Specifically, the light beam generation module is also provided with a polarization conditioning component for controlling the polarization state of the Gaussian light beam behind the laser.
Specifically, a first reflecting mirror is arranged between the spatial light modulator and the polarization conditioning assembly, and a second reflecting mirror is arranged between the spatial light modulator and the lens assembly.
In particular, the end of the lens assembly is further provided with a third mirror.
Specifically, the lens assembly includes a first lens and a second lens sequentially disposed on an optical path.
Specifically, the spatial light modulator includes an L CoS panel, and is aluminized with a reflective film.
Specifically, the imaging module comprises a charge-coupled device and a fast photodiode, wherein the charge-coupled device is used for imaging the light beam of the output coupling mirror lens, and the fast photodiode is used for detecting the light beam reflected and transmitted by the input coupling mirror and transmitting the light beam to the oscilloscope for imaging.
The invention has the advantages that:
(1) the invention adopts a mode of introducing dove prism in the ring cavity to effectively divide different OAM carrying light beams. Since the rotational symmetry of the two OAM-carrying beams with opposite topological charges is broken, their transmission spectra are split within the ring cavity. When the cavity is matched to the mode and impedance of one OAM-carrying beam, which is transmitted through the cavity, and the other OAM-carrying beam is reflected, both beams will retain their spatial shape, i.e., such that the degenerate state of the two OAM-carrying beams with opposite topological loads is changed to the non-degenerate state.
(2) The mode detector in the prior art is a projector, and N projection measurements are needed to measure N OAM modes, one disadvantage of the method is that the original state is completely destroyed after measurement, and the efficiency is not high.
(3) The dove prism is a right-angle prism with a cut-off top end, so that the weight of the prism and the internal reflection of stray light are reduced.
(4) The beam generation module causes two OAM carrier beams having opposite topological loads to change from a degenerate state to a non-degenerate state.
(5) The present application improves the purity of the input beam by increasing the front tilt phase of the spatial light modulator.
(6) The polarization state of the Gaussian beam can be controlled by arranging the polarization conditioning assembly.
(7) The first reflector and the second reflector are used for adjusting the angle of the light beam at the input end and the output end of the phase modulation component.
(8) The third reflector adjusts the direction of the output light path of the light beam generation module.
(9) The first and second lenses form a 4-F system to maintain beam parameters constant.
(10) The imaging module images the output OAM carrier beam.

The input modes are the transmission spectra of |0> + |1>, |1> + |2>, |1> + |1> and | -2> + |2>, respectively, as shown in FIGS. 6(a) -6 (d). For high topology OAM modes, more extraneous high cavity modes appear in the transmission spectrum due to the resonance of the impurities and other modes of the input mode. Since the cavity loss of the higher OAM mode is also higher, larger diffraction and scattering losses occur, resulting in lower transmission efficiency. In the device of the present invention, the transmittance T of the cavity is 0.90, and the total mode and impedance matching coefficient is about 0.80 to 0.90, which means that the reflectance of the resonant mode is about 0.10 to 0.20.

Thus obtaining: the emitted beam has a pronounced circular shape and high mode purity, while the reflected beam is distorted by the partially reflected resonant mode due to mode mismatch. The image of fig. 7(b) is the result of a corresponding theoretical simulation based on experimental parameters.
The invention is not to be considered as limited to the specific embodiments shown and described, but is to be understood to cover all modifications, equivalents, and alternatives falling within the spirit and scope of the invention as defined by the appended claims.
