“…The CNC/SB-2 film shows a main component of L-CPLE, regardless of the specific excitation (L-CP or R-CP laser, Figure a). To quantify the polarization degree of the laser output, the dissymmetry factor, g , is used: , where I L , I R denote the intensities of the emitted L-CP and R-CP light, respectively. For a perfect chiral photonic structure, the maximum | g | is 2.…”

Circularly polarized (CP) lasers derived from low-cost and renewable raw sources are attracting increasing attention in photonics and material science. Here, we present a facile and effective approach to fabricate CP lasers by the evaporation-induced assembly of cellulose nanocrystals (CNCs) and a laser dye. The obtained laser exhibits a controlled chiral nematic structure, which acts as a chiral optical cavity, and varied chiral coupling interactions. It is shown that the CNC-based laser can modify the polarization state of the laser into left-handed polarization, leading to strong CP laser emission (CPLE) with a dissymmetry factor up to 0.35. The chiral nematic CNC structure proves to be a versatile yet straightforward strategy to generate strong and tailored CPLE.

“…Additionally, to realize CP light, perovskites' optical response is engineered by coupling with some photonic architecture that is chiral [81], [82]. This approach has so far been exercised for the case of a semiconductor "gallium nitride nanolasers" [83], "InAs quantum dots (QDs)" [84], and by combining the plasmonic chiral metasurfaces with colloidal CdSe/ZnS QDs [85] for generating high fractions of CPL. A remarkable CD effect due to chirality transfer has been perceived through electron beam lithography for the example of MAPbI3 [26].…”

Nature has implanted chirality in many organic molecules of living organisms that have made man think about exploiting this handedness property of the objects and coming up with exciting applications through synthetic chiral structures. In this connection, several chiral metasurface designs have been proposed with interesting optoelectronic applications, such as chiral sensing of a molecule at the zeptomole level, circularly polarized luminescence, circular dichroism, chiro-spintronics, and nonlinear optics. The perovskites' unique chirality features have led to the emerging perovskite optoelectronic area. In this regard, exploiting the novel chiral perovskite materials for optoelectronic functionalities becomes vitally important. This area of research is at a pre-mature stage. The present issues associated with perovskite semiconductors are toxicity, reproducibility, and instability. However, the expertise from physics, chemistry, and device engineering from the perovskite research community has been focusing on the basic material properties, fabrication, and characterization methods while simultaneously mitigating the present issues to get to successful commercialization. Future research opportunities related to chiral perovskite nanocrystals are versatile and intend to rationalize the exceptional potential of these low-cost materials for complicated optoelectronics applications.

The scientific effort to control the interaction between light and matter has grown exponentially in the last 2 decades. This growth has been aided by the development of scientific and technological tools enabling the manipulation of light at deeply sub‐wavelength scales, unlocking a large variety of novel phenomena spanning traditionally distant research areas. Here, the role of chirality in light–matter interactions is reviewed by providing a broad overview of its properties, materials, and applications. A perspective on future developments is highlighted, including the growing role of machine learning in designing advanced chiroptical materials to enhance and control light–matter interactions across several scales.
