(a) Schematic representation of the three-layer technology for the monolithic optical stretcher fabrication. The central fused silica glass is machined by Femtosecond Laser Irradiation followed by Chemical Etching (FLICE) technique for the central channel and then sealed on both sides with two polished glass slides; (b) Microscope image of the straight microfluidic channel with pairs of waveguides beside it; (c) The finished chip is pigtailed with optical fibers and connected with external tubing through Luer connectors.
