Exploiting disordered optical systems for optofluidics
Transmission of light waves through disordered materials introduces randomization of intensity, phase and polarization into the signal. This renders many light based applications including imaging, optical micro-fabrication or manipulation impossible unless the initial light-waves are engineered to eliminate these randomizing effects.
Recent advances based upon computer holography allowed controllable propagation of light even through entirely randomizing systems such as diffusers, tissues or multimode waveguides. Moreover, it was shown that disorder could considerably enhance performance of imaging and other techniques. We will introduce these principles into optofluidic environments. Delivery of light via multimode waveguides is of a particular importance for these considerations, as it would eliminate a need for high NA optical access into the microfluidic channels and reactors. At the same time this may allow very compact lab-on-a-chip implementation of optofluidic environments.
