Abstract

1494535 Optical waveguide POST OFFICE 26 Oct 1976 [12 Nov 1975] 46740/75 Heading G2J A multi-mode dielectric optical waveguide has regions of reduced core diameter spaced apart by distances of for example greater than 10 metres but less than 100 metres i.e. long compared to the differences in wavelength between different modes.
