Monolithic two-dimensional optical fiber array

A two-dimensional (2D) optical fiber array component takes the form of a (relatively inexpensive) fiber guide block that is mated with a precision output element. The guide block and output element are both formed to include a 2D array of through-holes that exhibit a predetermined pitch. The holes formed in... Ii vi Incorporated

Thin film plasmonic optical modulator

A plasmon-based optical modulator comprises a substrate, a layer of high reflectivity material disposed over the substrate, a relatively thin dielectric layer disposed over a top major surface of the layer of high reflectivity material and a plurality of graphene strips disposed in parallel across a top major surface of... Ii vi Incorporated

Compact laser source with wavelength stabilized output

A compact, wavelength-stabilized laser source is provided by utilizing a specialty gain element (i.e., formed to include a curved waveguide topology), where a separate wavelength stabilization component (for example, a fiber Bragg grating (FBG)) is used one of the mirrors for the laser cavity. That is, the FBG takes the... Ii vi Incorporated

Large diameter silicon carbide single crystals and apparatus and manufacture thereof

In an apparatus and method growing a SiC single crystal, a PVT growth apparatus is provided with a single crystal SiC seed and a SiC source material positioned in spaced relation in a growth crucible. A resistance heater heats the growth crucible such that the SiC source material sublimates and... Ii vi Incorporated

Compact optical fiber amplifier

A fiber-based optical amplifier is assembled in a compact configuration by utilizing a flexible substrate to support the amplifying fiber as flat coils that are “spun” onto the substrate. The supporting structure for the amplifying fiber is configured to define the minimal acceptable bend radius for the fiber, as well... Ii vi Incorporated

Edge propagating optical time domain reflectometer and using the same

An OTDR system utilizes a laser source that is turned “on” and kept powered until its light reaches the end of the fiber span being measured (i.e., until the fiber span is fully illuminated). At any point in time after the fiber is fully illuminated, the laser source can be... Ii vi Incorporated

Method of manufacture of free standing microwave plasma cvd polycrystalline diamond films with major dimensions on the order of one wavelength of the utilized microwave

A chemical vapor deposition (CVD) reactor includes a resonating cavity configured to receive microwaves. A microwave transparent window positioned in the resonating cavity separates the resonating cavity into an upper zone and a plasma zone. Microwaves entering the upper zone propagate through the microwave transparent window into the plasma zone.... Ii vi Incorporated

Immobilized selenium, a making, and uses of immobilized selenium in a rechargeable battery

An immobilized selenium body, made from carbon and selenium and optionally sulfur, makes selenium more stable, requiring a higher temperature or an increase in kinetic energy for selenium to escape from the immobilized selenium body and enter a gas system, as compared to selenium alone. Immobilized selenium localized in a... Ii vi Incorporated

Substrate comprising a layer of silicon and a layer of diamond having an optically finished (or a dense) silicon-diamond interface

A multilayer substrate can include a silicon layer having an optically finished surface and a chemical vapor deposition (CVD) grown diamond layer on the optically finished surface of the silicon layer. At the interface of the silicon layer and the diamond layer, the optically finished surface of the silicon layer... Ii vi Incorporated

Method of efficient coaxial delivery of microwaves into a mode stabilized resonating chamber for the purpose of deposition of microwave plasma cvd polycrystalline diamond films

Disclosed is a chemical vapor deposition (CVD) reactor includes a resonating cavity configured to receive microwaves. A microwave transparent window is disposed in the resonating cavity, intermediate a top and bottom of the resonating cavity, separating the resonating cavity into an upper zone and a plasma zone. The resonating cavity... Ii vi Incorporated

Optical channel monitor with integral optical switch

A multiport optical switch is used to controllably select a specific incoming optical signal that is to be processed by an associated optical channel monitor (OCM). The OCM includes a tunable optical filter and photodetector arrangement, and is configured to measure the optical spectrum of the incoming optical signal and... Ii vi Incorporated

Method and determining optical fibre characteristics

An optical amplifier assembly for determining a parameter of an optical fibre configured to amplify an optical signal being propagated therethrough, the assembly comprising: at least one amplifier pump light source assembly configured to transmit light at a plurality of wavelengths into the optical fibre; a receiver configured to receive... Ii vi Incorporated

Method of preparing and application of carbon selenium composites

Disclosed is method of preparing a selenium carbon composite material and a use of the selenium carbon composite material in a cathode of a lithium selenium secondary battery. A battery formed with a cathode of the disclosed selenium carbon composite material has high energy density and stable electrochemical performance. The... Ii vi Incorporated

Micro splice protector

A micro splice protector for a fusion connection between a pair of optical fibers takes the form of a cylindrical sleeve of dimensions similar to that of the fusion splice itself, with an epoxy material used to encase the fusion splice within the sleeve. The sleeve is formed to exhibit... Ii vi Incorporated

Optical channel monitor with integral optical switch

A multiport optical switch (such as an N×1 switch) is used to controllably select a specific incoming optical signal that is to be processed by an associated optical channel monitor (OCM). The OCM includes a tunable optical filter and photodetector arrangement, and is configured to measure the optical spectrum of... Ii vi Incorporated
