20100289594MODULATOR DRIVER CIRCUIT HAVING CHIRPED COMPONENTS - Embodiments of the present invention provide arrays of electrical circuits having one or more chirped elements or components for providing output signals to corresponding arrays of electro-optic devices. Certain embodiments of the present invention include a plurality of modulator driver circuits, each of the plurality of driver circuits configured to be substantially identical to each other and provide a corresponding one of a plurality of modulator drive signals to a respective one of a plurality of electro-optic modulators, each of the plurality of modulator driver circuits being chirped to provide a desired output to the corresponding electro-optic modulator for enhanced operation. Each of the plurality of modulator driver circuits comprises a plurality of electrical components, at least one of the electrical components being chirped such that a design or operating parameter of the electrical component differs from an electrical component having a similar function in at least one of the remaining modulator driver circuits of the plurality of driver circuit. In certain embodiments, each of the plurality of modulator driver circuits is provided on a common substrate.11-18-2010

20130127558Method for Providing a Modulation Scheme - A method for providing a first modulation scheme based on a second modulation scheme, the second modulation scheme including a first constellation point associated with a first bit pattern and a second constellation point associated with a second bit pattern. The method includes mapping the second bit pattern from the second constellation point to the first constellation point, wherein an energy associated with the second constellation point is greater than an energy associated with the first constellation point.05-23-2013
