  • Optical tweezers based on total internal reflection micro-optics mounted on the tip of a single mode optical fiber
    Patent number: 11923102
    Abstract: The present disclosure relates to a rotationally symmetric dielectric structure for optical beam shaping and for trapping and manipulating individual particles and living biological cells in aqueous medium, concentrically mounted on the facet of a single-mode optical fiber, wherein the structure comprises at least three total reflection surfaces configured to split a light field emerging from the single-mode optical fiber into at least two separate light paths and wherein the at least three total reflection surfaces are further configured to bring the separate light paths together as a ring beam in a common focal point.
    Type: Grant
