A connector that provides alignment of an optical fiber to a photonic device. The connector has a threaded sleeve, a ferrule cavity, an aperture in optical communication with the ferrule cavity and having a center that is substantially aligned with a center of the ferrule cavity and a device cavity that is configured to receive the photonic device and further in optical communication with the ferrule cavity via the aperture.

Connector for photonic device

An optical power transfer device with an embedded active cooling chip is disclosed. The device includes a cooling chip made of a semiconductor material, and a first subassembly and a second subassembly mounted on the cooling chip. The cooling chip comprises at least one metallization layer on a portion of a first surface of the cooling chip, at least one inlet through a second surface of the cooling chip, wherein the second surface is opposite to the first surface, at least one outlet through the second surface and one or more micro-channels extending between and fluidly coupled to the at least one inlet and the at least one outlet. A cooling fluid flows through the one or more micro-channels. The first subassembly is mounted on the at least one metallization layer and comprises a laser. The second subassembly comprises a phototransducer configured to receive a laser beam from the laser.

Optical power transfer devices with an embedded active cooling chip

An optical transducer system that has a light source and a transducer. The light source generates light that has a predetermined photon energy. The transducer has a bandgap energy that is smaller than the photon energy. An increased optical to electrical conversion efficiency is obtained by illuminating the transducer at increased optical power densities. A method of converting optical energy to electrical energy is also provided.

Transducer to convert optical energy to electrical energy

An optical transducer, optoelectronic device, and semiconductor are disclosed. An illustrative optical transducer is disclosed to include a plurality of p-n stacks, where each p-n stack comprises at least a p-layer and an n-layer, and formed therein a built-in photovoltage between the p-layer and the n-layer. The p-layers and n-layers are disclosed to have substantially the same n-type material in substantially the same composition such that each p-n stack in the plurality of p-n stacks has a substantially similar built-in photovoltage. The optical transducer is further disclosed to include a plurality of connecting layers, each connecting layer in the plurality of connecting layers being sandwiched between two adjacent p-n stacks for electrically connecting the two adjacent p-n stacks. The p-n stacks in the plurality of p-n stacks may be arranged such that the built-in photovoltage of each p-n stack additively contributes to an overall electric potential of the transducer.

A transducer to convert optical energy to electrical energy. The transducer or photo-transducer has a base layer which has a group of connecting elements formed therein at separations which are increasing with the distance away from an emitter layer formed atop the base layer. The connecting elements separate and electrically connect the base layer into base segments, the base segments having increasing thicknesses with the distance away from the emitter layer. The photo-transducer generates an output voltage that is greater than the input light photovoltage. The photo-transducer output voltage is proportional to the number of connecting elements formed in the base layer.

A solar cell and a method of fabricating solar cells. The method includes a step of separating neighbor solar cells formed on a semiconductor wafer by scribing the wafer to form scribe lines on the wafer and applying a force at, or adjacent to, the scribed lines to separate the solar cells. The scribing is effected on a cap layer covering a window layer of solar cells, thereby minimizing damage to the window layer and mitigating propagation of defects into p-n junctions formed in the solar cells.
