“…This could enable enhanced polarisation imaging resolution physically via beam shaping and compensation of polarisation errors 277 – 280 . Thirdly, the emerging techniques based on metasurfaces—subwavelength arrays of nano-scatterers that can modify polarisation—have been adopted for polarimetry 281 , as well as for 3D polarisation control 282 . Such developments may bring new opportunities for advanced biomedical polarimetry, such as forming compact vectorial sensors 24 , 283 for deep tissue information extraction.…”

Many polarisation techniques have been harnessed for decades in biological and clinical research, each based upon measurement of the vectorial properties of light or the vectorial transformations imposed on light by objects. Various advanced vector measurement/sensing techniques, physical interpretation methods, and approaches to analyse biomedically relevant information have been developed and harnessed. In this review, we focus mainly on summarising methodologies and applications related to tissue polarimetry, with an emphasis on the adoption of the Stokes–Mueller formalism. Several recent breakthroughs, development trends, and potential multimodal uses in conjunction with other techniques are also presented. The primary goal of the review is to give the reader a general overview in the use of vectorial information that can be obtained by polarisation optics for applications in biomedical and clinical research.

“…It is assumed that the light is incident on the metasurface from the air. The phase difference approaches

in the wavelength range from 700 to 900 nm, which satisfies the properties of a half-wave plate [ 35 , 36 , 37 ]. Due to the phase change, the direction of the rotation is opposite when circularly polarized light impinges on the half-wave plate.…”

Chiral-selective Tamm plasmon polariton (TPP) has been investigated at the interface between a cholesteric liquid crystal and a metasurface. Different from conventional TPP that occurs with distributed Bragg reflectors and metals, the chiral–achiral TPP is successfully demonstrated. The design of the metasurface as a reflective half-wave plate provides phase and polarization matching. Accordingly, a strong localized electric field and sharp resonance are observed and proven to be widely tunable.

“…Surprisingly, the geometric variables, rather than the material conformation of nanostructures, govern the amplitude, phase, polarization, and even dispersion of spherical wavelets. The wavefront can be shaped at will in this way to produce flat optical elements with superior performance, even multifunctional ones, or to structure light by forming vector beams with complete control of polarization, which would otherwise need multiple optical components and be outside the competence of spatial light modulators (SLMs) [ 160 ]. This technique has been used to suggest and explain BB generators based on MS [ 161 ].…”

Axicon is a versatile optical element for forming a zero-order Bessel beam, including high-power laser radiation schemes. Nevertheless, it has drawbacks such as the produced beam’s parameters being dependent on a particular element, the output beam’s intensity distribution being dependent on the quality of element manufacturing, and uneven axial intensity distribution. To address these issues, extensive research has been undertaken to develop nondiffracting beams using a variety of advanced techniques. We looked at four different and special approaches for creating nondiffracting beams in this article. Diffractive axicons, meta-axicons-flat optics, spatial light modulators, and photonic integrated circuit-based axicons are among these approaches. Lately, there has been noteworthy curiosity in reducing the thickness and weight of axicons by exploiting diffraction. Meta-axicons, which are ultrathin flat optical elements made up of metasurfaces built up of arrays of subwavelength optical antennas, are one way to address such needs. In addition, when compared to their traditional refractive and diffractive equivalents, meta-axicons have a number of distinguishing advantages, including aberration correction, active tunability, and semi-transparency. This paper is not intended to be a critique of any method. We have outlined the most recent advancements in this field and let readers determine which approach best meets their needs based on the ease of fabrication and utilization. Moreover, one section is devoted to applications of axicons utilized as sensors of optical properties of devices and elements as well as singular beams states and wavefront features.
