“…Additionally, studies on OAM light beams have shown promising applications in various fields. For instance, in the field of optical communication, infinite orthogonal OAM states of an optical vortex can be applied for mode division multiplexing, and this can be incorporated along with other existing multiplexing approaches such as polarization multiplexing 6 , and data encoding to implement a realization of very large capacity information transmission 7 , 8 .

Higher orders of orbital angular momentum states (OAMs) of light have been produced with a double-pass configuration through a zero-order vortex half-wave retarder (VHWR). This double-pass technique can reduce the number of VHWR plates used, thus reducing costs. The OAM states of the vortex beams are identified by the near-field Talbot effect. Polarization dependence of the vortex states can also be demonstrated with this VHWR using Talbot effect. Without using the Talbot patterns, this effect of the polarization on the vortex beam can not be recognized. A theoretical validation has also been provided to complement the experimental results. Our study gives an improved understanding of this approach to use a VHWR plate.

“…Since then, OAM of light was a promising means for exploiting the spatial dimension of light to increase the communication capacity. However, the bottleneck to implement this technique relies on the generation and detection of OAM states, either inside free space optic (FSO) [12] or in optical fibers [13]. In addition, OAM is also used in optical imaging [14], quantum communication field [15], and so on.…”

Orbital angular momentum (OAM) with mutually orthogonal advantage attribute to break through the high capacity and long-reach transmission limited in the classical passive optical network (PON). Employing Laguerre Gaussian (LG) mode as the orthogonal OAM excitation, a more dimensional multiplexing PON system is proposed to creatively hybridize OAM division multiplexing (OAM-DM) based on wavelength division multiplexing (WDM) and orthogonal frequency division multiplexing (OFDM). By utilizing the compatibility of OAM-DM and WDM, data of 40 Gbit/s OFDM signals is successfully transmitted in 80 km multimode fiber (MMF) with low crosstalk. Within this hybrid system, the effects of different wavelengths and different modes on the bit error rate (BER) are discussed at varying transmission distances. Moreover, the performance of several subsystems carrying quadrature phase-shift keying (QPSK), on-off keying (OOK), and OFDM modulation signals is also compared at a BER less than 3.8×10−3. It is observed that the proposed OAM-DM-WDM-OFDM-PON system has favorable performance, which is a reasonable solution for large-capacity PON architecture.

“…In particular, orbital angular momentum (OAM) beams [3], also called optical vortices (OVs), offered a new degree of freedom to encode information in classical communications [4] or increase the Hilbert state space in quantum applications [5,6], while their peculiar intensity and phase distributions enabled innovative and advanced techniques in microscopy [7], micro-manipulation [8], and light-matter interaction [9]. Concurrently, the necessity to tailor and control this spatial property of light inspired the design and engineering of new techniques with different levels of complexity and integration [10][11][12][13][14]. Among all, spiral phase plates (SPPs) [15] represent one of the first optical elements purposely introduced to impart orbital angular momentum to common non-structured beams.…”

The capability of multiple orbital angular momentum (OAM) modes generation with high resolution and diversified functionalities in the visible and near-infrared regime is challenging for flat and integrated optical devices. Additionally, having a static tiny optical device capable of generating multiple structured spots in space reduces the complexity of optical paths that typically use dynamic optical components and/or many standard elements, leading to unprecedented miniaturization and compactness of optical systems. In this regard, we propose dual-functional transmission dielectric metalenses based on a set of Pancharatnam-Berry phase meta-atoms with different cross-sections, for the combined manipulation of the dynamic and geometric phases. In particular, we present and describe the numerical algorithms for the computation of dual-functional metaoptics and we apply those techniques to the design of optical elements which are able to generate and focus different OAM modes at distinct points in space. In the specific, the designed elements enable the independent or simultaneous manipulation of right-handed and left-handed circularly polarized waves, by acting on the helicity of the input beam to enable or disable a specific optical operation. The theoretical proof-of-concept results highlight the capability of the designed metalenses to generate multiple high-resolution focused OAM modes at different points in space by exploiting the polarization of the incident beam as a degree of freedom, thus providing new integrated optics for applications in the fields of high-resolution microscopy, optical manipulation, and optical communications, both in the classical and single-photon regimes.
