SINGLE-POLARIZATION SINGLE-MODE PHOTONIC CRYSTAL FIBER AND OPTICAL TRANSMISSION METHOD USING THE SAME

摘要

PURPOSE: A single polarization and single mode photonic crystal optical fiber and an optical waveguide method using the same are provided to guide certain frequency of light in the single polarization and single mode. CONSTITUTION: A single polarization and single mode photonic crystal optical fiber(100) is comprised of a first core(110), a cladding(140), a second core(120), and a third core(130). The cladding covers the first core and includes a plurality of a first hole. The second core is located in the cladding and includes a second hole. The third core is located in the cladding and includes a third hole.
