Methods for forming optical systems are provided. A representative method includes the steps of: providing a substrate; depositing on the substrate a first contoured channel preform of material capable of ion exchange with the substrate; and diffusing ions from the first channel preform into the substrate to form a first waveguide channel at least partially buried in the substrate. Optical systems and other methods also are provided.

Optical systems incorporating waveguides and methods of manufacture

An integrated-optic attenuator/equalizer device comprising a photorefractive substrate, at least one optical waveguide channel formed in the substrate, at least one diffractive-Bragg grating formed in the substrate, and a diffractive-Bragg grating modulator that is capable of modulating the diffractive Bragg grating(s). The diffractive-Bragg grating(s) intersects the optical waveguide channel. When a diffractive-Bragg grating formed in the substrate is modulated, at least a fraction of light of a wavelength associated with the modulated diffractive-Bragg grating is re-directed by the modulated diffractive-Bragg grating, thereby preventing the re-directed fraction of light from arriving at the output of the optical waveguide channel. Multiple diffractive-Bragg gratings may be implemented in the integrated-optic device, each having a particular wavelength associated therewith, and the diffractive-Bragg gratings may be simultaneously or independently modulated to control the fractions of light of different wavelengths that arrive at the output of the optical waveguide channel.

Integrated-optic device and a method for attenuating light or equalizing light using integrated-optic device

An integrated-optic device comprising a photorefractive substrate, an optical waveguide channel and at least one diffractive Bragg grating integrated in the substrate and intersecting the optical waveguide channel. The diffractive Bragg grating(s) causes at least a fraction of light coupled into the optical waveguide channel to be coupled out of the optical waveguide channel.

Integrated-optic out-coupler device and method for making and using the same

The invention relates to a wavelength-tunable laser configuration. The interspace between a laser source (,) and a control element (,), forming an external cavity, is short and has a length of preferably at most a few hundreds of wavelengths of the laser source (,). Also, the control element (,) is electrically tunable, which means that the control element (,) changes the optical properties of the external cavity with a movement of at least one tuning part (,).
