Vortex Waveplates and Phase Plates are advanced optical components designed to generate vortex beams and vector-polarized beams by introducing azimuthally varying phase or retardation across the beam profile. These devices transform a standard Gaussian beam (TEM₀₀) into a donut-shaped intensity distribution with a helical phase front, enabling precise beam shaping and orbital angular momentum (OAM) generation.

Vortex Waveplate Array

The Vortex Waveplate Array integrates multiple vortex waveplate elements with different topological charges into a compact array format, enabling simultaneous generation of multiple vortex beam modes. Fabricated on an N-BK7 glass substrate with a liquid crystal polymer (LCP) layer, it provides uniform λ/2 retardation and high-efficiency beam conversion.

Polymer Vortex Waveplate

The Polymer Vortex Waveplate is constructed using a sandwich structure of front and rear glass substrates with a central liquid crystal polymer (LCP) functional layer. The fast-axis orientation of the liquid crystal molecules is radially aligned and continuously varies along the azimuthal direction, enabling precise phase modulation and vortex beam generation.

Polymer Achromatic Vortex Waveplate

The Achromatic Vortex Waveplate is designed for broadband operation with stable retardation across a wide wavelength range. The fast-axis orientation rotates continuously over 360° azimuth, ensuring consistent vortex beam generation within the specified spectral band.

Spiral Phase Plate

The Spiral Phase Plate is a diffractive optical element designed to generate vortex beams by introducing a helical phase modulation through controlled height variation along the azimuthal direction. When a plane wave passes through the plate, it transforms into a vortex beam with a spiral phase front and a central dark core.
