Custom Spatially Variable Waveplates

Workshop of Photonics

Spatially variable waveplates fabrication is based on inscription of self-organized nanogratings inside fused silica glass using a femtosecond laser. Rapid prototyping enables adaptation of every element to the specific needs of end user without high additional development costs. Current technology allows fabrication of SVW with retardance from R=200nm to R=1000nm. The wavelength range for which it is possible to fabricate λ/2 waveplates is λ=400nm to λ=2µm. - Radial polarization - Azimuthal polarization - Random polarization - Circular polarization - Elliptical polarization - Custom polarization - Optical vortex generation - Flattop generation S-waveplate is the most common availabe spatially variable waveplate.
