  • Method of adjusting the operation characteristics of integrated optical devices
    Patent number: 5359682
    Abstract: 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.
    Type: Grant
    Filed: August 17, 1992
    Date of Patent: October 25, 1994
