AI Article Synopsis
- The study introduces two techniques for independently focusing light with orthogonal linear polarizations at any desired positions.
- The first method employs a displaced lens in a polarization Sagnac interferometer to achieve flexible focal adjustments through geometric means, while the second method uses uniaxial crystals in a compact arrangement.
- The authors discuss the theoretical implications and constraints of their methods and verify their predictions through experimental results.
Article Abstract
We present two methods for the precise independent focusing of orthogonal linear polarizations of light at arbitrary relative locations. Our first scheme uses a displaced lens in a polarization Sagnac interferometer to provide adjustable longitudinal and lateral focal displacements via simple geometry; the second uses uniaxial crystals to achieve the same effect in a compact collinear setup. We develop the theoretical applications and limitations of our schemes, and provide experimental confirmation of our calculations.
