DEVICE INCLUDING AN OPTICAL GUIDELINE SUSTAINED BY A SUBSTRATE AND MANUFACTURING METHOD.

摘要

IN THE MANUFACTURE OF OPTICAL DEVICES LIKE, FOR EXAMPLE, OPTICAL COMMUNICATION MECHANISMS AND OPTICAL GYROSCOPES, GUIDES OF OPTICAL WAVES SUPPORTED BY A LOW-LOSS SUBSTRATE ARE NEEDED. SUCH WAVE GUIDES CAN BE OBTAINED BY DESIGNING A LAYER OF WAVE GUIDED MATERIAL DEPOSITED AND, IN ORDER TO MINIMIZE THE LOSS THAT MAY BE INDUCED BY THE PROCESSING, THE SOUNDED GUIDES OF THE ASEÑAS SUBJECTED TO HEAT TREATMENTS WHICH PROVIDES A POLISHED SURFACE AND A ROUNDING OF THE CROSS SECTION OF THE WAVE GUIDES. IN ADDITION, IN ORDER TO AVOID ENTERING CORNERS BETWEEN THE SUBSTRATE AND THE ONDSA GUIDE, A HUMIDIFYING COAT MAY BE APPLIED TO THE WAVE GUIDE BEFORE SUBMITTING IT TO HEAT TREATMENT.
