Abstract: A colored light source apparatus is provided. The apparatus includes light sources corresponding to active regions defined by defects in a photonic crystal structure, wherein the photonic crystal structure is based on periodic structures. The apparatus also includes a waveguide, a first electrode, and a second electrode. Varying electrical properties between the first and second electrodes stimulates radiation production in the active regions, wherein the radiation is at least partially coupled to and guided by the waveguide.

Abstract: A method of manufacturing a periodic grating structure for a component. The method includes forming first structured layer including a final periodic grating structure of a first material and a second material filling spaces between individual features of the final periodic grating structure, removing the second material using a first chemical process and annealing a portion of the first material into a third material using a second chemical process.

Abstract: A backup system stores configuration data for several interdependent systems in a single backup store. As the systems are being configured and when changes are made to the systems, the backup store is updated with the change. The systems may be configured with each system having a designated role. During a restore operation, an otherwise unallocated system may assume a particular role and use the configuration logic defined for the role that may be taken from the backup store. The system may perform the restore in conjunction with the other systems and the interdependencies with the systems.

Abstract: In detecting presence of a gas, light passes through a photonic crystal cavity configured to sample a gas and receive light. The light has a wavelength that at least partially falls within a specific absorption wavelength of the gas. At least one parameter of a band gap spectrum is generated from at least a portion of the light passing through the photonic crystal cavity. In generating the at least one parameter, a numerical simulation is performed within a frequency range of the photonic crystal cavity to generate a set of spectral response data points, rational function interpolation is performed on the set of spectral response data points to generate a spectral response, and at least one parameter is determined from the spectral response. The at least one parameter is compared with stored parameters of band gap spectrums, wherein a match indicates a presence and/or concentration of the gas.

Abstract: A variety of technologies related to the management of computer licenses for accessing services are applied. Licenses can be purchased in a dynamic license pack. Dynamic license packs can be activated and stored. Licenses can be automatically provisioned. License provisioning rules can be used to automatically provision licenses to licensable resources, and once provisioned the assignments can be stored. Licenses can be enforced across a single machine or service or across multiple machines or services. Services can enforce licensing by checking license assignments for licensable resources attempting to access the service. Licensing services can check and maintain licensing consistency. Licensing services can also generate promotion codes in order to support promotions.
