Abstract

An ideal optical waveguide consists of uniform square cores of material having a high index of refraction clad with or imbedded in a matrix of material having a lower refractive index. The separation between each of these cores must have a minimum thickness m to prevent optical coupling between adjacent waveguides. In actual practice it has been impossible to produce optical waveguides with only the necessary spacing m since the present chemical etching process used to create such waveguides cannot create a separation having a width less than the height of the waveguide itself.
