摘要： An optical fiber combiner comprises a double-clad fiber (DCF) and one or more multimode fibers (MMFs). DCF comprises a transition portion, a DCF taper portion, and an output section coupling to the DCF taper portion, whereas each of MMFs comprises an MMF taper configured to be fused around DCF in the transition portion. MMFs are configured to carry a combined optical energy (COE) and to couple to DCF. COE passes through the MMF taper with larger divergence of higher-order modes generated and coupled into DCF, whereas the DCF taper portion can partially offset the larger divergence. COE coupled, when traced through the output section, emerges in the air with a smaller output beam divergence of the higher-order modes, thereby preserving some of the higher-order modes in the output section and increasing a coupling efficiency of COE coupled from MMFs to DCF with improved thermal performance.

摘要： A water-cooled package of an optical fiber combiner (OFC) comprising an OFC assembly, a front end cap (EC), a rear EC, and a housing operates for long term reliability. The OFC assembly comprises two submounts and an OFC. Each of the two submounts comprises a U-groove in a lengthwise direction and two flat portions symmetrically connected to the U-groove in a widthwise direction. The two flat portions of each of the two submounts are mechanically coincident in a way to form a cavity between the two U-grooves of the two submounts, in which the OFC is fixed. When the OFC assembly is concentrically mated and sealed with the front EC and the rear EC, cooling water in the water-cooled package is prevented from immersing the OFC. The configurations can minimize varying stress-induced optical degradations and maintain beam quality of a laser light exiting the OFC.

摘要： A light-emitting diode (LED) lamp using an LED driving circuit, at least two frequency sensitive devices, at least six diodes configured to convert an AC voltage into a DC voltage and manage electric current flows, a switch control module, and a return current switch operates normally with an input voltage from either ballast or line voltages of AC mains. The LED driving circuit may be configured to operate normally only with the AC mains providing a regulated power and a current to LED arrays. When an input AC voltage is applied to the LED lamp, the at least six diodes and the at least two frequency sensitive devices can detect the input AC voltage, control electric current flowing into the switch control module or the LED driving circuit, and complete current returns so that the LED lamp can operate with either the ballast or the AC mains without operational ambiguity.

摘要： A wireless fiber optic endface inspector includes a video microscope capable of wirelessly transmitting video streaming signal of endface image in real-time to a display device. The video microscope includes a microscope optical system, an adapting tip for interfacing an endface, an LED light source, a camera module for receiving and converting the endface image into video streaming signal, a Wi-Fi AP board, and a battery for supplying power. The video microscope may be constructed by adding a Wi-Fi AP board and a battery to a conventional inspector microscope. The display device has software for detecting when the endface is focused. Once the endface is focused, the display device emits an audio signal to alert the operator, who may then trigger the display device to analyze the endface image using an endface analysis software or save it to a folder, or transmit the image to a remote server.

摘要： An LED lighting device with a replaceable driver-control module interface is described. The LED lighting device may include a driver-less LED lighting device, a driver-control module with driver function, and a housing interface on the driver-less LED lighting device to house and connect the driver-control module. The driver-less LED lighting device receives AC from an external AC source and passes the AC to the driver-control module. The driver-control module receives AC from the driver-less LED lighting device and provides DC to the driver-less lighting device to drive LED diodes in the driver-less LED lighting device. The housing interface on the lighting device houses the driver-control module such that, when the driver-control module is fastened to the driver-less lighting device through the housing interface, the driver-control becomes an integral part of the lighting device.

摘要： A linear light-emitting diode (LED)-based solid-state universal lamp using an all-in-one LED driving circuit with a power factor correction (PFC) and control device operates normally for a regulated power and current from either electronic ballast or AC mains. The all-in-one LED driving circuit is configured to operate in a wide range of input voltages and frequencies, especially for various high voltages and high frequencies associated with various electronic ballasts. With a cycle-by-cycle current control and power switching at a constant on-time and varied off-time, an over-rated surge current is limited, preventing occasional fire hazards occurred in the ballast. When two shock protection switches are used in two lamp bases in the lamp, the universal lamp fully protects a person from possible electric shock during initial installation and re-lamping.

摘要： A dimming and CCT tuning system comprises a controller and multiple LED-based lighting devices. Each lighting device comprises a control circuit, at least two LED driving circuits, and at least two types of LED-based light sources. When the controller receives the dimming and CCT tuning signals from its inputs, it generates a modulated dimming and CCT tuning signal portion in the AC voltage delivered to the multiple lighting devices. Afterwards, a regular AC power is delivered. In receiving, each lighting device demodulates such signal portion and generates at least two control signals to the at least two LED driving circuits which then individually power the at least two types of LED-based light sources to emit desired light levels and CCTs. The system eliminates extra wires required in 0-10 V dimming control and maintains an undistorted AC waveform in most of operating time, not like a TRIAC dimming.

摘要： A device for shifting the imaging axis of a microscope for inspecting endfaces of a fiber-optic connector having multiple rows of endfaces has a supporting body for receiving a microscope; a first swinging lever mounted on top of the supporting body and rotatable about a first swinging axis perpendicular to the imaging axis of the microscope; a first connecting piece extending from the first swinging lever towards the imaging axis; a second swinging lever pivoted on the first connecting piece and rotatable about a second swinging axis perpendicular to the first swinging axis; and a fitting tip connected to the second swinging lever for interfacing with the fiber-optic connector. Using two sets of biasing means and adjustment drivers, the imaging axis passing through the supporting body and the fitting tip can be shifted in two mutually perpendicular directions to selectively align with any endface of the fiber-optic connector.
