WebThe chief drawback of subwavelength gratings is the nonuniformity of the Fresnel reflection coefficient that arises because of the nonuniformity of a crystal's refractive indices. Web12 Apr 2024 · Optical vortices have myriad applications in photonics. Very recently, promising concepts of spatiotemporal optical vortex (STOV) pulses based on the phase helicity in the space–time coordinates have attracted much attention owing to their donut shape. We elaborate on the molding of STOV under the transmission of femtosecond …
