Charles Kao was the pioneer who suggested using glass fibre waveguide as a means of carrying laser-light over long distances for telecommunications traffic. In his seminal paper published in 1966, he spelled out the appropriate design parameters and performance characteristics that would be needed for a successful system to emerge. At the time, the idea was widely ridiculed. Within a few years, however, in a brilliant set of spectrophotometric experiments, Kao demonstrated that pure silicon…

Stimulated Optical Radiation in Ruby

Schawlow and Townes1 have proposed a technique for the generation of very monochromatic radiation in the infra-red optical region of the spectrum using an alkali vapour as the active medium. Javan2

A type of device is described which can be used as a microwave amplifier, spectrometer, or oscillator. Experimental results are given. When operated as a spectrometer, the device has good

Dielectric-fibre surface waveguides for optical frequencies

A dielectric fibre with a refractive index higher than its surrounding region is a form of dielectric waveguide which represents a possible medium for the guided transmission of energy at optical

RADIATION LOSSES IN GLASS OPTICAL WAVEGUIDES

Measurements show that single‐mode waveguides can be constructed which have radiation losses of about 7 dB/km—very close to the intrinsic material scattering loss. These waveguides, with total losses
