A system and method are disclosed for a rapidly tunable wavelength selective ring resonator. An embodiment of a voltage-tunable wavelength selective ring resonator includes a ring-shaped waveguide formed on a semiconductor substrate, an electro-optic cladding layer formed over the ring-shaped waveguide, and voltage applying means for applying a voltage across the electro-optic cladding layer. The ring-shaped waveguide is configured to propagate optical signals having predetermined resonant wavelengths, the electro-optic cladding layer has a voltage-controlled variable refractive index, and the means for applying is configured to apply a wavelength-specific control voltage to the electro-optic cladding layer. The wavelength-specific control voltage will shift or tune the predetermined resonant wavelengths for the ring-shaped waveguide.

A system and methods are disclosed for a hybrid silicon-organic scalable reconfigurable optical add-drop multiplexer. An embodiment of a scalable reconfigurable optical add-drop multiplexer (ROADM) includes an optical bus for optical signals of different wavelengths, a plurality of add/drop optical waveguides, and a plurality of ring resonators, each being optically coupled to the optical bus and to one of the add/drop optical waveguides. The ring resonators are coated with an organic electro-optic cladding layer and are configured to switch wavelength selected optical signals between the optical bus and the add/drop optical waveguides in response to control voltages applied to the organic electro-optic cladding layer. The individual ring resonators of the ROADM can be independently modulated and tuned to filter specific wavelengths.

摘要:
Structured data sets including one or more attributes are identified, each structured data set associated with, for example, a particular user. Values corresponding the at least one of the one or more attributes in each structured data set are identified. A condition established by a content provider, for instance, an advertiser, is compared to the identified values to determine if the condition is satisfied. When the condition is satisfied, one or more content items are identified to the users associated with the structured data sets containing identified values satisfying the condition.

A request for content is received. First content is selected for the request. The first content is selected from among multiple content items based on information in the request, a characteristic of how the first content is to be presented, and a stored pricing threshold value selected based on the characteristic. The characteristic of how the first content is to be presented includes an amount of available space that is occupied by the first content when the first content is presented. The selected first content is provided for presentation by a publisher that provides second content.

摘要:
An apparatus for providing electrooptic modulation. The apparatus includes electrical contacts, a waveguide coupled between the electrical contacts, and a nonlinear optical material positioned in the slot region. The waveguide includes a first arm and a second arm that are each arranged to define a slot region for confining an optical mode. The slot region has a height, t1, and each of the first arm and the second arm include a strip load region having a height that is less than the height, t1, of the slot region. Each of the first arm and the second arm is configured to provide an electrical signal to the slot region via at least one of the electrical contacts. In one embodiment, the nonlinear optical material includes a χ2-based material. In another embodiment, each of the first arm and the second arm have an “L”-type shape.
