Doppler velocimetry on microparticles trapped and propelled by laser light in liquid-filled photonic crystal fiber.

Laser Doppler velocimetry is used to measure very accurately the velocity and position of a microparticle propelled and guided by laser light in liquid-filled photonic crystal fiber. Periodic variations in particle velocity are observed that correlate closely with modal beating between the two lowest order guided fiber modes.
