Title: Optical fiber type phase element
Inventor: KUZUMI NAOTO
IPC: G02B6/14
Filed: 1989-09-01
Abstract: PURPOSE:To obtain the optical fiber type phase element being useable in a wide band by constituting it so that with respect to an optical fiber having a core whose refractive index is higher than a refractive index of a clad of the periphery, a refractive index distribution of a cross sectional shape becomes non-axisymmetyric through an intermediate clad whose refractive index is lower than it between its core and the clad. CONSTITUTION:In a clad 11 whose refractive index is nc and whose outside peripheral cross section is circular, a core 12 which is eccentric against its axis center O1, whose refractive index is n1 and whose cross section is circular is embedded and n1>nc is set, and between the clad 11 and the core 12, an intermediate clad 13 is interposed. A refractive index nD of the intermediate clad 13 is made smaller than the refractive index nc of the clad 11. In this case, since this element is formed by an optical fiber structure, it can be incorporated easily into an optical fiber circuit system, and also, due to existence of the intermediate clad, a first higher order mode is suppressed. In such a way, a wavelength band for giving a roughly constant phase difference between orthogonal polarized waves is wide.
