摘要： The present invention relates to a method for writing an optical structure within a workpiece of a dielectric material using FLDM. In a first embodiment system parameters for the FLDM are determined in dependence upon the dielectric material, a predetermined volume element and a predetermined change of the refractive index of the dielectric material within the predetermined volume element. The system parameters are determined such that self-focusing of a pulsed femtosecond laser beam is inhibited by non-linear absorption of the energy of the pulsed femtosecond laser beam within the dielectric material. A pulsed femtosecond laser beam based on the determined system parameters is focused at a predetermined location within the workpiece for inducing a change of the refractive index through dielectric modification within the predetermined volume element, the volume element including the focus. Various embodiments enable writing of various different optical structures into a workpiece.

摘要： A method for adjusting a photosensitive optical waveguide having an optical path length to a stabilized desired optical path length. The method includes the step of changing the optical path length of the photosensitive optical waveguide by exposing at least a first portion of the waveguide to actinic radiation and creating an induced index change in the exposed first portion. The waveguide then is subjected to an annealing cycle that stabilizes the waveguide. After the step of stabilizing the waveguide, the optical path length is adjusted by subjecting at least a selected part of the exposed first portion of the waveguide to a localized heating to change the refractive index at the selected part until the desired optical path length is achieved.

摘要： The present invention provides a direct laser writing fabrication method and system for devices having periodic refractive index modulation structures, for example, Bragg gratings. By focusing a modulated pulsed laser beam into a transparent material substrate, a path of laser modified volumes can be formed with modified refractive index compared with the unprocessed material. Modulation of exposure conditions provides periodic or modified periodic waveguide structures such that the waveguide structures exhibit grating responses and can be used for a variety of optical applications, for example, as spectral filters, Bragg reflectors, grating couplers, grating sensors, or other devices. The method enables direct one-step fabrication and integration of periodic or modified periodic refractive-index modulation devices together with other optical waveguiding devices to enable low-cost, multifunctional one-dimensional, two- dimensional or three-dimensional optical circuit fabrication of simple and complex optical systems.

摘要： The present invention is concerned with a process for fabricating a ridge waveguide, and an optical waveguide comprising this ridge waveguide. More specifically, the ridge waveguide is fabricated from an optical waveguide made of superposed cladding layer, core layer and, possibly, a buffer layer. By modifying two laterally adjacent strips of the optical waveguide from the outer surface of the cladding layer, a ridge waveguide is formed between these two modified strips. The modification can be made by direct laser micromachining two trenches in the optical waveguide. In one embodiment, the modified strips or trenches extend from the outer surface of the cladding layer and at least throughout the thickness of the cladding layer and at most throughout the thickness of the cladding layer and a part of the thickness of the core layer. In another embodiment, the trenches extend at least throughout the thickness of the cladding layer and can dig throughout the core layer. Advantageously, the trenches will present a Gaussian profile.
