Abstract: In certain examples, methods and optically-engineered structures involve three-dimensional (3D) or volumetric metamaterials, having a grayscale dielectric profile, to produce a certain electromagnetic response. In more specific examples, the 3D metamaterial may be implemented to approximate a grayscale continuum of dielectric constants, and may conform to curved and/or irregular shapes for use in a wide variety of applications such as electromagnetic devices wherein to operate via communication of radiating waves to be steered and/or manipulated as a function of frequency.

Abstract: In certain examples, aspects are directed to using a first beamsplitter and a second beamsplitter arranged with respect to one another with the first beamsplitter splitting incident light into multiple light beams, along a particular polarization basis, and with the second beamsplitter recombining and interfering with the multiple light beams to provide a recombined light beam characterized as having at least one of the following attributes: mapping between a polarization state and different wavelengths of the incident light; and a polarization tuning of the incident light.

Abstract: A method for optimization of photonic devices is disclosed. The method includes receiving a set of unconstrained latent variables; mapping the set of unconstrained latent variables to a constrained space to generate a constrained device; calculating the permittivity across each element of the constrained device; determining a permittivity-constrained width gradient based at least partially on the permittivity across each element; and optimizing the set of unconstrained latent variables by at least partially using the permittivity-constrained width gradient.

Abstract: The present invention provides electronic circuits, devices and device components including one or more stretchable components, such as stretchable electrical interconnects, electrodes and/or semiconductor components. Stretchability of some of the present systems is achieved via a materials level integration of stretchable metallic or semiconducting structures with soft, elastomeric materials in a configuration allowing for elastic deformations to occur in a repeatable and well-defined way. The stretchable device geometries and hard-soft materials integration approaches of the invention provide a combination of advance electronic function and compliant mechanics supporting a broad range of device applications including sensing, actuation, power storage and communications.

Abstract: Various systems and methods for providing access to a dynamically generated rules table as a Web Service are disclosed. One method involves receiving a Web Service request from a requester and then dynamically generating a rules table, in response to receipt of the Web Service request. Dynamically generating the rules table includes accessing one or more matrices that store information associated with multiple different rules tables. For example, dynamic generation of the rules table can involve accessing a dimension matrix that stores information identifying one or more input criteria and one or more results included in the rules table, selecting information from a rules matrix based upon the criteria and results identified by the dimension matrix, and then storing the selected information from the rules matrix in the rules table.

Abstract: The present invention provides electronic systems, including device arrays, comprising functional device(s) and/or device component(s) at least partially enclosed via one or more fluid containment chambers, such that the device(s) and/or device component(s) are at least partially, and optionally entirely, immersed in a containment fluid. Useful containment fluids for use in fluid containment chambers of electronic devices of the invention include lubricants, electrolytes and/or electronically resistive fluids. In some embodiments, for example, electronic systems of the invention comprise one or more electronic devices and/or device components provided in free-standing and/or tethered configurations that decouple forces originating upon deformation, stretching or compression of a supporting substrate from the free standing or tethered device or device component.

Abstract: An apparatus for collimating radiation can include an aperture of subwavelength dimensions and a neighboring set of grooves defined on a metal film integrated with an active or passive device that emits radiation. Integration of the beam collimator onto the facet of a laser or other radiation-emitting device provides for beam collimation and polarization selection. Beam divergence can be reduced by more than one order of magnitude compared with the output of a conventional laser. An active beam collimator with an aperture-groove structure can be integrated with a wide range of optical devices, such as semiconductor lasers (e.g., quantum cascade lasers), light emitting diodes, optical fibers, and fiber lasers.
