Abstract: The invention provides a method of processing an optical signal having a first amplitude frequency or gain frequency profile so as to produce a desired second amplitude frequency or gain frequency profile, the method comprising subjecting the signal to action by a plurality of chirped gratings each of which is designed to act upon a respective wavelength band of said signal and to remove at least a part of the radiation in said band and operating the gratings such that the proportion of the radiation removed from the respective band is such as to alter the first profile to the second profile within that band. The electrodes define a plurality of adjacent independently adjustable filter segments along the waveguide. Each filter segment functions over a specific range of wavelengths, where the center-to-center wavelength difference between adjacent segments and the wavelength bandwidth of each segment are defined in large part by the chirp in the grating. In a preferred embodiment of the invention, the grating is divided into two consecutive chirp regions, both of which span the desired wavelength band. The first chirp region is divided into a first group of independently adjustable filter segments. The second chirp region is divided into a second group of independently adjustable filter segments spaced such that the central wavelengths of the second group of filter segments are interleaved between the center wavelengths of the first group of filter segments a set of overlapping filter functions that can be used to create very smooth attenuation versus wavelength profiles.

Abstract: The present invention discloses practical and power efficient assemblies for applying a temperature gradient to a fiber Bragg grating. An application of such assemblies is, for example, the active tuning of the chromatic dispersion of the grating. The temperature gradient is produced in a heat conductive element, with which the FBG is in continuous thermal contact, by elements controlling the temperature of the ends of the heat conductive element, thereby applying the temperature gradient to the FBG. A first preferred embodiment includes a heat recirculation member allowing the recirculation of heat between the two ends of the heat conductive elongated element, thereby providing a rapid and dynamical tuning of the temperature gradient with a minimal heat loss. A second embodiment provides isolation from the surrounding environment in order to decouple the desired temperature gradient from ambient temperature fluctuations, thereby improving the control of the optical response of a fiber grating.

Abstract: An optical delay generator comprises a first waveguide made from electro-optically active material resonantly coupled to a second non-electro-optically active waveguide. The first waveguide contains a chirped distributed Bragg reflector structure which reflects optical signals at a specific wavelength at a specific reflection point within the structure. An electric field applied to the first waveguide changes the refractive index of the electro-optically active material and thus shifts the reflection point. Optical signals reflecting from the reflection point are resonantly coupled into the second waveguide, and are thus not affected by the electric field applied to the first waveguide. The controllable optical delay applied to the optical signals results from control over the reflection point and the round-trip travel time for an optical signal forward propagating in the first waveguide, being reflected at the reflection point, and backward propagating in the second waveguide.

Abstract: An optical device directed at controlling wavelength transmission in a waveguide is disclosed. The basic device comprises a substrate containing an optical waveguide, a layer containing a grating, a variable refractive index layer and a set of electrodes for selectively applying a local temperature at points along the waveguide. The grating is disposed sufficiently close to the optical waveguide to be within the evanescent coupling field of the guided beam. The waveguide and variable index materials have significantly different thermo-optical coefficients of refractive index such that the differential thermal coefficient between the variable index material and the substrate can be used to vary the interaction strength between the guided wave and the grating. The grating may be formed as a phase grating within the variable index layer. Alternatively the grating and variable index medium may be in separate layers. The grating may be a surface relief grating backfilled with a variable index material. The grating may be configured as a chirped grating.

Abstract: Programmable waveguide coders are disclosed that include one or more corrugation segments and one or more spacer segments formed on or in a waveguide defined by a core in an electro-optic substrate. Each of the corrugation segments and the spacer segments are independently controllable with voltages applied to each segment's electrodes. The spacer segments permit application of a phase modulation to an input while the corrugation segments act as tunable gratings, wherein a center grating wavelength is tunable by applying a voltage to an electrode associated with the corrugation segment. In some embodiments, coders include only corrugation segments or only spacer segments. Such coders can be strain tuned or thermally tuned. The coders can be programmatically tuned to code or decode a time-wavelength code or other code.

Abstract: An optical modulation apparatus includes an optical signal input section, an optical signal propagation path, an optical modulator that modulates the phase of optical signals in at least two of a plurality of optical paths, and a wavelength selective filter that selectively reflects and transmits. Optical signals input via the input section are divided into a plurality of optical paths at a branching point and phase modulated by the phase modulator, that divides the optical path into a plurality of optical paths. Light transmitted by the filter is output via the output section, while light reflected by the filter travels back along the optical path and is again phase modulated by the phase modulator combined at the branching point and output from the input section as an intensity modulated optical signal.

Abstract: Disclosed is a tunable optical filter which may be used in telecommunications systems. The filter comprises a single mode optical waveguide containing a grating. The resonance wavelength of the filter is changed by changing the boundary condition at the interface between the cladding layer and an additional layer applied to the outer cladding layer surface. This boundary condition is changed by changing the refractive index of the additional layer. Means for changing the refractive index of the additional layer include establishing a structural resonance in the additional layer, or forming the additional layer from electro-optic or piezoelectric materials.
