Abstract:
An embodiment of the invention relates to an optical device which is capable of realizing a secondary nonlinear optical phenomenon. The optical device is a fiber-type optical device which is comprised of glass containing SiO 2 , and includes a core region, a first cladding region, and a second cladding region. At least a part of a glass region configured by the core region and the first cladding region has such a repetition structure that a first section serving as a poled crystal region and a second section serving as an amorphous region are alternately disposed along a longitudinal direction of the optical device.

Claim (Index 19):
A method for manufacturing an optical device, comprising:\n a preparation process of preparing an optical fiber comprised of glass containing SiO 2 , the optical fiber including a core region which extends along a longitudinal direction of the optical fiber, a first cladding region which surrounds the core region and has a refractive index lower than that of the core region, and a second cladding region which surrounds the first cladding region and has a refractive index lower than that of the core region, wherein at least a part of a glass region configured by the core region and the first cladding region includes a doped region containing a dopant for accelerating glass crystallization continuously provided along the longitudinal direction; a temperature adjusting process of maintaining a surface temperature of the optical fiber to fall within a range of 100\u00b0 C. to 800\u00b0 C.; and a section forming process of forming a repetition structure in the doped region by forming an electric field passing through the doped region in middle of or after an intermittent irradiation of a laser beam to the doped region of the optical fiber, the repetition structure including a first section serving as a poled crystal region and a second section serving as an amorphous region, the first section and the second section being alternately disposed along the longitudinal direction, wherein the laser beam is intermittently emitted to the doped region along the longitudinal direction to form the repetition structure in the doped region, and wherein the electric field is formed such that a potential gradient is formed in the doped region along a direction perpendicular to the longitudinal direction.
