TOM 12 Optofluidics

Light confinement in liquid crystals for optofluidic integrated microsystems

Antonio d'Alessandro, Anju M. Kumaran

Sapienza University, Italy

In this paper technology to make optical waveguides and microfluidic channels integrated on the same substrate will be reported to envisage micro-optofluidic chips. Both silicon based and polymeric materials are used to make microchannels to be filled with biological solutions. Liquid crystals are used to confine light to produce optical interaction with biological fluidic specimen. Electro-optic effect of liquid crystals is used to make tuneable optical waveguides to tune the entire optofluidic microsystem which can include gold nanoparticles for photo-thermal therapies. Examples of photonic devices will be reviewed and discussed.

TOM 12 Optofluidics

Controlling matter by optical solitons in liquid crystals

Ivan Smalyukh

University of Colorado Boulder, United States of America

Liquid crystals are known to be characterized by strong nonlinearities, thus hosting both optical and topological solitons. This lecture will discuss various long- and short-range interactions that arise between the two types of solitons, as well as topological defects within the liquid crystalline host medium. The lecture will conclude with an overview of potential technological applications, ranging from telecommunications to unconventional optical manipulation of matter and to model systems of gravitational field interactions with light in cosmology.

Toward novel optofluidic concepts via topological microfluidics

Anupam Sengupta

University of Luxembourg, Luxembourg

The coupling between flow and orientation of liquid crystal (LC) molecules underpin LC-based optofluidic platforms. I will discuss emerging optofluidic concepts which leverage topological microfluidics, through a tunable flow-mediated defect landscape. With a specific focus on the role of surface anchoring and confinement geometry, I will explore non-intrusive optomechanical measurements through birefringent readouts. The flow-induced optical attributes can be enhanced further by controlled generation of topological defects. The rich interplay of confinement, anchoring and hydrodynamics makes topological microfluidics a promising platform to ideate next generation of optofluidic and optomechnical concepts.
