Holographic optical tweezers at the tip of a needle
in: 2018 IEEE Photonics Society Summer Topical Meeting Series (SUM) (2018)
Fibre-based optical tweezers typically rely on engineered fibre terminations yielding limited flexibility in number and positioning of trap sites. Here, we demonstrate holographic optical tweezers delivered by a lensless, high-NA multimode fibre with full positioning control of multiple tweezers independently and in all directions.
