摘要： A method of producing a material for single mode optical fiber comprises the steps of making a core rod from a vitreous substance, coating the core rod with a cladding layer to a desired diameter, and dehydrating and vitrifying it. When this material is drawn into optical fiber, the diameter of its core rod is at least 1.9 times the mode field diameter through which light having a wavelength of 1.55 mu m travels. As a result, the glass material for single mode optical fiber has small influences of structural defects.

摘要： An asymmetric lens wherein lens optical characteristics projected on two planes which are in parallel with a lens optical axis and orthogonally cross each other are mutually different, which lens is characterized by satisfying the following simultaneous equations: (w 2)/(w 1) = (f 2)/(f 1) [2]; (w$(1,3)$2)/(w$(1,3)$1) = (f$(1,3)$2)/(f$(1,3)$1) [3]; (d1) = |(s 1) - (s$(1,3)$1)| [4]; (d2) = |(s 2) - (s$(1,3)$2)| [5]. Since this lens has asymmetry stipulated by the simultaneous equations described above, it can provide ideal optical coupling with low loss between optical waveguides having mutually different waveguide modes, between optical waveguides having mutually dissimilar waveguide shapes, between optical waveguides having astigmatism in their radiation patterns, etc.
