Abstract:
A study of fluorescent nanoparticles suspended in liquids within hollow-core photonic bandgap fiber. Common solvents deionized water and deuterium dioxide(D2 O) were used to replace the air in hollow-core photonic badgapl fibers and determine bandgap and loss effects on the waveguide. A fluorescent dye, indocyanine green, is then used to test the interaction of the fiber mode with particles suspended within the fiber. Following promising results, the use of carbon nanotubes, a nanomaterial with desirable optical properties is discussed and their overlap with the bandgaps of liquid-filled hollow-core photonic bandgap fibers are determined.
