摘要

An optical fiber, which has a zero-material dispersionwavelength equal to or greater than 2 µm, and a highnonlinear susceptibility .chi.3 equal to or greater than 1 x-12 esu, and uses tellurite glass having sufficientthermal stability for processing into a low loss fiber,employs a PCF structure or HF structure having strongconfinement into a core region. This enables light topropagate at a low loss. The size and geometry of air holesformed in the core region, and the spacing between adjacentair holes make it possible to control the zero dispersionwavelength within an optical telecommunication window(1.2-1.7 µm) , and to achieve large nonlinearity with anonlinear coefficient .gamma. equal to or greater than 500W-1km-1.
