Optical chromatography is a simple and promising passive sorting technique, which utilizes the interplay between microfluidic drag force and the optical radiation force to achieve spatial separation of microparticles. Optical fibers are routinely used in liquid chromatographic detectors as a means of simplifying optical designs. The analysis builds on our previously reported Fourier Transform method to obtain Beam Shape Coefficients for any beam. Total internal reflection (critical angle, using Snell's law). Higher bandwidth (extremely high data transfer rate). Lower transmitter. Abstract: We describe the realization of integrated optical chromatography, in conjunction with on-chip fluorescence excitation, in a monolithically fabricated poly-dimethylsiloxane (PDMS) microfluidic chip. The unique endlessly-single-mode guiding property of the Photonic Crystal Fiber (PCF). Optical Fiber Communication (OFC) revolutionizes modern telecommunications, enabling rapid data transfer across long distances with minimal signal loss. Briefly, particles in a fluid flow are subject to two forces, the Stokes drag force due to the fluid and.
