“…Notably, it allows for the generation of arbitrarily specified polarization states on the diffraction orders and equivalently, polarimetry with an arbitrarily specified set of basis polarizations. We note that a similar approach with similar functionality has been demonstrated using liquid crystal spatial light modulator technology [57,58]. Owing to the constraints of these SLMs, however, a relatively complex double-pass architecture relying on a waveplate and a polarization beamsplitter must be employed in order to impart independent phase profiles on x and y polarized light independently, limiting the scope of potential applications.…”

The constituent elements of metasurfaces may be designed with explicit polarization dependence, making metasurfaces a fascinating platform for new polarization optics. In this work we show that a metasurface grating can be designed to produce arbitrarily specified polarization states on a set of defined diffraction orders given that the polarization of the incident beam is known. We also demonstrate that, when used in a reverse configuration, the same grating may be used as a parallel snapshot polarimeter, requiring a minimum of bulk polarization optics. We demonstrate its use in measuring partially polarized light, and show that it performs favorably in comparison to a commercial polarimeter. This work is of consequence in any application requiring lightweight, compact, and low-cost polarization optics, polarimetry, or polarization imaging.

“…Some authors have shown the interest of generalizing the Billet-lens scheme to N -split lens sectors 29 , 32 , 33 . The coordinate system chosen to split the lens, strongly influences the light-dots distribution that can be created at the focal plane by using split schemes.…”

We present an experimental method, based on the use of dynamic split-lens configurations, useful for the trapping and spatial control of microparticles through the photophoretic force. In particular, the concept of split-lens configurations is exploited to experimentally create customized and reconfigurable three-dimensional light structures, in which carbon coated glass microspheres, with sizes in a range of 63–75 μm, can be captured. The generation of light spatial structures is performed by properly addressing phase distributions corresponding to different split-lens configurations onto a spatial light modulator (SLM). The use of an SLM allows a dynamic variation of the light structures geometry just by modifying few control parameters of easy physical interpretation. We provide some examples in video format of particle trapping processes. What is more, we also perform further spatial manipulation, by controlling the spatial position of the particles in the axial direction, demonstrating the generation of reconfigurable three-dimensional photophoretic traps for microscopic manipulation of absorbing particles.

“…In both displays, the liquid crystal director is aligned horizontally with respect to laboratory framework. The retardance was calibrated at room temperature as a function of the addressed gray level in both modulators for the operating wavelength of 633 nm [16]. The phase modulation produced in both displays is only for the linear polarization component parallel to LC director, and therefore only modulates the horizontal component of polarization.…”

“…Finally, Section 6 present the conclusions of the work. Figure 1 shows the optical setup, which was previously introduced in [16]. It uses two phaseonly parallel-aligned LCoS-SLMs, arranged in a Z architecture, in order to independently modulate two orthogonal polarization components, as introduced in [17].…”

We report the realization of polarization sensitive split lens configurations. While split lenses can be used to easily generate different types of controlled structured light patterns, their realization has been limited so far to scalar beams. Here we propose and experimentally demonstrate their generalization to vectorial split lenses, leading to light patterns with customized intensity and state of polarization. We demonstrate how these polarization split lenses can be experimentally implemented by means of an optical system using two liquid crystal spatial light modulators, each one phase modulating one orthogonal polarization component. As a result, we demonstrate the experimental generation of vectorial beams with different shapes generated with these dual polarization split lenses. Excellent experimental results are provided in each case. The proposed technique is a simple method to generate structured light beams with polarization diversity, with potential applications in polarimetry, customized illuminators or quantum optics.
