Fabrication of micro/nano fiber by using focused high-repetition-rate CO2 laser pulses
Optical micro/nanofiber and its application Definition: Fiber waveguides with a submicrometric diameter are referred as optical fiber nanowires (or photonic nanowires): OFN. Those ones with diameter bigger than 1 μm are referred to optical fiber microwires (OFMs)
Purpose of this study • Optimize the fabrication approach for micro/nano fiber by using focused high-repetition-rate CO2 laser pulses • Explore the new applications of the micro/nano fiber • (For examples: Fiber Bragg gratings formed in a nano-fiber • LPGs formed in a nano-fiber • Chiral grating formed in nano/micro fiber)
Experimental results Before the Laser exposure After the laser exposure and the fiber pulling process
Measuring results by using AFM Length 20 [mm], Dia. D= 455.5[nm] Length 18 [mm], Dia. D= 534.4 [nm]
Transmit spectrum (1) The fiber is lengthened about 1 mm The fiber is lengthened about 5 mm
Transmit spectrum (2) The fiber is lengthened about 10 mm
