An optical waveguide fiber and method of making photonic band gap fibers

摘要

photonic bandgap fiber of the manufacturing method includes a plurality of internal passages (14) having a matrix (12) after etching , and a step of drawing the matrix 12 to the photonic band gap fiber . The etching of the matrix 12, the device 10 includes a storage section 28 for accommodating the etchant (18) in the liquid state . The heater 30 is thermally connected to the storage section 28 . Circulator 32 is connected with a storage unit 28, a circulator 32 draws the etchant 18 to the drain line 40 is connected to the matrix (12) . The etchant 18 is directed into the interior passage 14 of the matrix 12 . The apparatus is connected to the matrix 12 and etchant 18 to be returned to the return line to the storage section 28 (50) also comprises a
