Using the guided wave path for hardening optical introduction

摘要

PROBLEM TO BE SOLVED: To scan a growing end in a desired direction when forming a self-formation optical waveguide.;SOLUTION: A manufacturing method comprises steps of: dipping one end 10ae of an optical fiber 10a and one end 10be of a similar optical fiber 10b into a photosetting resin liquid 11; introducing a laser beam having a wavelength of 488 nm from an argon laser into the other end of the optical fiber 10a to irradiate the photosetting resin liquid 11 from the first end 10ae and forming a cured product by a self-forming process; condensing a control beam having a wavelength of 800 nm from a mode-lock titanium sapphire laser near the growing end of the cured product and scanning the area; scanning the condensed point of the control light at a velocity of 0.2 mm/min matched with the growing speed of 0.2 mm/min of the cured product, to smoothly connect the one end 10ae of the optical fiber 10a to the one end 10be of the optical fiber 10b; and obtaining the cured product 11c in a form of a gently curved shaft.;COPYRIGHT: (C)2009,JPO&INPIT
