摘要： A vertical cavity surface emitting laser (VCSEL)-based free space active optical transceiver component is provided, which includes: a transmitter that includes a plurality of VCSELs (12), at least one photodiode (13), a first focusing lens array (14) or a first optical system (14), and a first printed circuit board (11); and a receiver that includes a plurality of photodiodes (22), at least one VCSEL (23), a second focusing lens array (24) or a second optical system (25), and a second printed circuit board (21). The transmission and reception of a short/medium-distance free space (wireless) high-speed optical communication signal can be implemented, and a single-channel transceiving rate may reach 10 Gbps or higher. The component may be used for implementing a free space high-speed signal transmission function in a short/medium-range high-definition multimedia interface (HDMI) device. In addition, the component also has the characteristics of free space connection, high transmission rate, low cost, small size, easy assembly and mass production, etc., and has a broad market prospect.

摘要： A buried grid double junction barrier Schottky diode may include a drift layer, a grid layer comprising a plurality of grid segments at least partially in the drift layer, a regrown layer on the grid layer and the drift layer, and first and second Schottky material layers. The grid segments may define at least one grid spacing area between adjacent grid segments. The first Schottky material layer may be at least partially on the regrown layer and may at least partially overlap the grid segments of the grid layer. The second Schottky material layer may be at least partially on the regrown layer and may at least partially overlap the grid spacing area(s). The second Schottky material layer may have a different Schottky barrier height than the first Schottky material layer. A method of making a buried grid double junction barrier Schottky diode is also disclosed.

摘要： An optical polarizer includes a dielectric substrate and a number of elongated dielectric ridges positioned or disposed in spaced relation on a surface of the substrate. Each dielectric ridge has a length direction, curved or straight, that extends along the surface of the substrate. Each dielectric ridge also includes a pair of spaced sides that extend away from the surface of the substrate and a top extending between the spaced sides opposite the surface of the substrate. Each side of each dielectric ridge includes an electrically conductive coating.

摘要： A display system includes a display screen layer, a coupling region, an upper guide, a first coupler, a second coupler, and an optical element. The coupling region may be positioned along a sidewall of the display screen layer and may route a beam between the optical element and the upper guide and may route the beam between the first coupler and the second coupler. The first coupler may be positioned along a front surface of the upper guide and may couple a beam through the front surface of the upper guide. The second coupler may be positioned between the coupling region and the upper guide and may couple the beam between the coupling region and the upper guide. The optical element may be positioned below a back surface of the upper guide. A computing device with the display system is also disclosed.

摘要： A colorless mux/demux cable assembly, including a first fiber optic cable, a second fiber optic cable, and a main body that includes an N:1 optical combiner and a 1:N optical splitter. The N:1 optical combiner is configured to combine individual optical signals received by each of N input fibers of the second fiber optic cable and provide a combined output signal to an output fiber of the first fiber optic cable. The 1:N optical splitter is configured to split a combined input optical signal (having N wavelength channels) received via an input fiber of the first fiber optic cable and provide a split output signal comprising each of the N wavelength channels to each of N output fibers of the second fiber optic cable.

摘要： An optical network element for a hardware configured optical network includes a first optical port that receives an input optical signal comprising receive control information from the hardware configured optical network. A demodulator optically coupled to the first optical port decodes the receive control information for configuring the optical network element. A modulator having an electrical modulation input that receives transmit control information imparts a modulation onto an optical carrier thereby generating a transmit optical control signal representing the transmit control information. A second optical port transmits the transmit optical control signal representing the transmit control information to the hardware configured optical network.

摘要： A system for communicating supervisory information between amplifier nodes in an optical communication network utilizes modulation of an included pump source to superimpose the supervisory information on data signals (typically customer data signals) propagating between the amplifier nodes transmitted customer signals. The modulated pump appears as a modulated envelope on the amplified data signal exiting the amplifier node, and may be recovered by suitable demodulation components located at the second node (i.e., the destined receiver of the supervisory information). The supervisory information may include monitoring messages, provisioning data, protocol updates, etc., and is utilized as an input to an included modulator, which then forms a drive signal for the pump controller.
