| Popis: | To control the diffraction properties of light using micro-structure optical fiber having internal structures are well known modern techniques that are employed for diverse applications of human life. If front part of the optical fiber is changed with Concave shape, it will act like a lens and light will be diffracted from the micro-lenses. Light coming out from these micro-lenses will interfere and different interference pattern are expected to be formed at the surface plane of any object. Using this phenomenon, we design micro-lens array (MLA) engraved optical fibers. The work presented in this paper provides a design concept and simulation results of Concave micro-lens array engraved optical fibers. The circular shape micro-lenses are considered for micro-structuring the optical fiber tip position. Light beam profile and light intensity are analyzed at various location after the end of fiber tip. The simulation results of this paper show that the MLA engraved optical fibers will be able to provide improved light output with intense light beam profile. |
