Abstract
We propose an optical stretcher based on all-fiber technology combined with Lab-on-a-Chip system for diagnosing bio-samples. Optical momentum transfer between the medium and cell surfaces induced stretching mechanical force along the beam direction. Non-diffracting beam was realized by multimode interference in optical fiber to provide a better efficiency than conventional Gaussian beam in the stretching ability. Simulation and experimental result are discussed.
