摘要:
One embodiment of the present invention relates to a light-emitting diode having one or more light-emitting layers, a pair of electrodes disposed on the light-emitting diode so that an operating voltage can be applied to generate light from the one or more light-emitting layers, and at least one external electrode in electronic communication with the one or more light-emitting layers. Applying an appropriate voltage to the at least one external electrodes at about the time the operating voltage is terminated extracts excess electrons from the one or more light-emitting layers and reduces the duration of electron-hole recombination during the time period over which the operating voltage is turned off.

A photonic connection includes a first fiber and a second fiber. The first fiber has a core with a first predetermined pattern defined on or in a facet thereof, and the second fiber has a core with a second predetermined pattern defined on or in a facet thereof. The second predetermined pattern is complementary to the first predetermined pattern such that the first fiber or the second fiber fits into another of the second fiber or the first fiber at a single orientation and position.

Various embodiments of the present invention are directed to photonic switches and switch fabrics employing the photonic switches. In one embodiment of the present invention, a photonic switch comprises a first waveguide disposed on a surface of a substrate in proximity to an opening in the substrate, and a second waveguide crossing the first waveguide and positioned in proximity to the opening in the substrate. The photonic switch includes a tunable microring resonator disposed on the surface of the substrate adjacent to the first waveguide and the second waveguide and configured with an opening aligned with the opening in the substrate. The photonic switch also includes a wire having a first end and a second end and configured to pass through the opening in the microring and the opening in the substrate.
摘要:
An optical sensor, sensing system and method of sensing employ a half-core hollow optical waveguide adjacent to a surface of an optical waveguide layer of a substrate. The half-core hollow optical waveguide and the adjacent optical waveguide layer cooperatively provide both an optical path that confines and guides an optical signal and an internal hollow channel. The optical path and channel extend longitudinally along a hollow core of the half-core hollow optical waveguide. The system further includes an optical source at an input of the optical path and an optical detector at an output of the optical path. A spectroscopic interaction between an analyte material that is introduced into the channel and an optical signal propagating along the optical path determines a characteristic of the analyte material.

An interconnect system has an optical transmitter mounted on a first circuit board and an optical receiver mounted on a second circuit board. The optical receiver can be nominally aligned to receive an optical signal through free space from the optical transmitter. Further, the optical receiver includes one or more light detectors, and an optical antenna coupled to direct incident light into the one or more light detectors.
