US 11,536,879 B2 · Elliptical beam design using cylindrical optics

Abstract

The disclosure describes various aspects of techniques for elliptical beam design using cylindrical optics that may be used in different applications, including in quantum information processing (QIP) systems. In an aspect, the disclosure describes an optical system having a first optical component having a first focal length, a second optical component having a second focal length and aligned with a first direction, and a third optical component having a third focal length and aligned with a second direction orthogonal to the first direction. The optical system is configured to receive one or more optical beams (e.g., circular or elliptical) and apply different magnifications in the first direction and the second direction to the one or more optical beams to image one or more elliptical Gaussian optical beams. A method for generating elliptical optical beams using a system as the one described above is also disclosed.
