광 섬유용 파장 필터Wavelength Filters for Optical Fibers

본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음Since this is an open matter, no full text was included.

제1도는 본 발명이 다른 파장 필터를 만드는데 이용되는 유리 재질의 굴절율을 도시한 그래프.1 is a graph showing the refractive index of a glass material used to make another wavelength filter of the present invention.

제2a도는 광 섬유의 횡단면도.2a is a cross-sectional view of an optical fiber.

제2b도는 제2a도에 도시된 광 섬유의 종단면도.FIG. 2B is a longitudinal sectional view of the optical fiber shown in FIG. 2A.

Claims (1)

광 섬유 또는 평면 도파관과 같은 광 도파로 장치를 구비하는 파장 필터에 있어서, 상기 장치의 도파부분과 클래딩 부분은 각각 서로 다른 굴절율이 n1과 n2을 가진 개질로 형성되고, 상기 굴절율의 차이 Δ=(n1-n2)는 이미 선택된 레벨보다 낮은 파장에서 상기 차이의 부로는 상기 레벨보다 높은 파장에서는 반전이 되는 형태로 광의 파장에 따라 변하는 것을 특징으로 하는 광섬유용 파장 필터.In a wavelength filter having an optical waveguide device such as an optical fiber or a planar waveguide, the waveguide part and the cladding part of the device are each formed by a modification having different refractive indices n 1 and n 2 , and the difference in refractive index Δ = (n 1 -n 2 ) is a wavelength filter for the optical fiber, characterized in that the change in the form of inversion in the wavelength higher than the level of the difference at a wavelength lower than the level already selected. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
