Optical transport of chlorella microorganisms using photogalvanic response of photorefractive mirror
Abstract
Optical trapping and transport are important techniques for controlling and manipulating biological microorganisms. A simple way for transporting microorganisms is an interference pattern motion formed by two laser beams. In this work we present all-optical photomechanical interferometer based on photogalvanic effect in photorefractive nonlinear mirror placed at one of the arms of Mach-Zender interferometer. This interferometer generates a moving interference pattern at speed determined by laser intensity thus demonstrating a "smart behavior". It has been shown experimentally that this device traps and transports algae chlorella microorganisms diluted in water.
