What is Optical Tweezers with OAM Beams?

Optical tweezers with OAM beams use structured light carrying orbital angular momentum to trap, rotate, and sort microparticles through precise angular momentum transfer.

This technique extends conventional optical tweezers by employing vortex beams like Laguerre-Gaussian or Bessel modes for 3D manipulation. Over 50 papers explore OAM transfer for particle rotation and sorting, with key reviews citing hundreds of applications (Yang et al., 2021, 683 citations; Shen et al., 2019, 2049 citations). Foundational work demonstrated OAM in Bessel beams for torque on particles (Volke-Sepúlveda et al., 2002, 419 citations).

Key Challenges

Why It Matters

OAM tweezers enable independent control of particle position and rotation, critical for microfluidics device assembly and cell biology studies like bacterial flagella rotation. In cell manipulation, they sort chiral particles without labels, advancing drug delivery systems (Wang and Chan, 2014, 376 citations). Applications extend to nanoscale trapping with plasmonic enhancements, impacting biophysics force measurements (Wang et al., 2011, 428 citations).

Key Research Challenges

OAM Transfer Efficiency

Transferring OAM from beams to bound particles suffers losses due to spin-orbit misalignment and absorption. Volke-Sepúlveda et al. (2002) calculated angular momentum density in Bessel beams, revealing azimuthal variations reducing torque. Yang et al. (2021) review highlights beam instability in tweezers setups.

High Topological Charge Stability

Generating stable high-order OAM beams for tweezers is limited by diffraction and propagation losses. Shen et al. (2019) detail manipulation from topological charge to singularities, noting singularity splitting challenges. Ramachandran and Kristensen (2013) discuss fiber-based vortices for stable delivery (442 citations).

Nanoscale Particle Rotation

Rotating nanoparticles requires overcoming Brownian motion and heating effects in tweezers. Wang et al. (2011) used plasmonic nano-tweezers with heat sinks for trapping and rotation (428 citations). Gao et al. (2017) outline micro-to-nano scale manipulation prospects, citing force gradient limitations.
