Abstract
An optical component and a manufacturing method therefor are provided, in which an optical member is arranged across a spot-size enlarged portion of an optical fiber. The spot-size enlarged portion is formed either by heating and drawing an optical fiber to reduce its diameter or by diffusing core dopant of an optical fiber outwardly while heating the same. The optical component functions as an optical filter, an optical attenuator, a polarizer, a wavelength division multiplexer/demultiplexer or the like, depending on selection of the optical member.
