A method of adjusting the operation of optical networks in terms of propagation constants of guided modes in integrated optical devices, allowing a considerable number of out of tolerance devices to be recovered by depositing on the surface where the optical guides are manufactured, once the normal fabrication process is completed, a further layer of transparent material of suitable size and refractive index.

Method of adjusting the operation characteristics of integrated optical

A pump system for lasers or amplifiers made of a waveguide presenting a monomode active region, in which the pump radiation is launched into a multimode guide surrounding the active region. The radiation is obtained as a sum of the radiations emitted by a plurality of independent sources.

Pump system for waveguide lasers or amplifiers

A method of adjusting the operation of bimodal optical networks in terms of propagation constants of guided modes in integrated optical devices, allowing a considerable number of out of tolerance devices to be recovered by depositing on the surface where the optical guides are manufactured, once the normal fabrication process is completed, a further layer of transparent material of suitable size and refractive index.
