The present disclosure relates to a telecommunications connector. The connector includes at least one connector portion including a front housing portion coupled to a rear housing portion, the front housing portion being rotatable relative to the rear housing portion about a longitudinal axis, the front housing portion including a ferrule and a latch, the latch defining front and rear ends and being pivotable relative to the rest of the front housing portion at a connection portion. A boot mounted on the telecommunications connector is movable longitudinally relative to the rear housing portion, wherein the boot is configured to engage at least a portion of the latch of the front housing portion and cause the latch to pivot relative to the rest of the front housing portion as the boot is moved relative to the rear housing portion.

An optical connector including a ferrule, an outer housing, and a latch is disclosed. The ferrule holds an optical fiber at a front end of the optical connector. The outer housing is located closer to a rear end of the optical connector than the ferrule. The latch is connected to the outer housing and extends from a proximal end toward the front end of the optical connector. The latch includes an engaging part to engage with an external device at a distal end thereof. The latch is configured such that the engaging part is pushed down toward the ferrule. The engaging part includes an engaging main body and an engaging protrusion protruding outwardly from the engaging main body. The engaging protrusion includes an engaging surface to engage with the external device at a rear of the engaging protrusion, and an edge of the engaging surface is chamfered.

Devices such as multiports comprising connection ports with associated securing features and methods for making the same are disclosed. In one embodiment, the device comprises a shell, at least one connection port, at least one securing feature passageway, and at least one securing feature. The at least one connection port is disposed on the multiport with the at least one connection port comprising an optical connector opening extending from an outer surface of the multiport to a cavity of the multiport and defining a connection port passageway. The at least one securing feature is associated with the connection port passageway, and the at least one securing feature is disposed within a portion of the at least one securing feature passageway.

Disclosed is an exchangeable laser unit and an array thereof. The exchangeable laser unit includes cartridge receivers and housings having a uniform shape and uniform optical interfaces. The cartridge receiver adopts the optical interface including a tapered cavity and cylindrical cavity, so that a precise mechanical connection can be achieved between the output of laser of the cartridge receiver and the output of the optical fiber of the housing without professional tools, facilitating standardization of the output components of the laser elements of the cartridge receiver. In addition, the upper-lower guide rails and the upper-lower channels having certain of inclination degree can realize the precise positioning of the cartridge receiver and the housing. When replacing one laser element by a laser element that emits laser with a different wavelength, it is only necessary to replace the cartridge receiver inside the housing. That is, the replacement of laser elements having different wavelengths is converted to the replacement of cartridge receivers, which greatly reduces the difficulty for medical personnel to switch laser wavelengths, and improves the popularization of laser therapeutic instruments in the medical field. In the exchangeable laser array of the disclosure, the cartridge receiver inside the housing can be replaced by other cartridge receiver that emits laser with a different wavelength, and the plurality of housings can be connected with a plurality of wavelength switchers in the back to realize selective output of the wavelength.

A method for fabricating a photonic device is provided. The method includes patterning a semiconductor layer to form a waveguide structure, a semiconductor structure connected to the waveguide structure, and a dummy semiconductor structure disconnected from the waveguide structure and the semiconductor structure; epitaxially growing an epitaxial semiconductor feature over the semiconductor structure and a dummy epitaxial semiconductor feature over the dummy semiconductor structure; depositing a first capping film over the epitaxial semiconductor feature and the dummy epitaxial semiconductor feature; depositing a second capping film over the first capping film, wherein an oxide concentration of the second capping film is greater than an oxide concentration of the first capping film; and patterning the first and second capping films to form at least a dummy composite capping layer over the dummy epitaxial semiconductor feature.

Fiber optic connectors, connector housings, connectorized cable assemblies, and methods for the connectorization of cable assemblies are provided with particular cable adapter features, adapter extensions, multi-diametrical sealing flexures, subcutaneous sealing elements, and combinations thereof, for improved connector and cable performance, integrity, and durability.

Disclosed is an optical interconnection device that includes an alignment ferrule assembly formed from an alignment substrate and optical fibers. The optical interconnection device also has an alignment assembly formed by a planar support member with guide features. A receiving region resides between the guide features in which the alignment substrate is secured. An evanescent optical coupler can be formed using the optical interconnection device as a first device and another optical interconnection device as a second device. The second device is constituted by a planar lightwave circuit that operably supports waveguides and an adapter. The adapter of the second device is configured to engage the alignment assembly of the first device to place the optical fibers and the optical waveguides of the respective devices in evanescent optical communication.

A release member is mounted at the port of a plug receptacle to enable removal of a plug connector from the port. The plug connector is devoid of releasing structure to enable removal of the plug. The release member moves parallel to or coaxial with a plug insertion axis of the port. The release member is biased to a non-actuated position separately from a plug lock being biased to a locking position. The release member can carry a polarity indicator for the port; various shaped actuation sections; and/or a biasing member for the release member.

Devices such as multiports comprising connection ports with associated securing features and methods for making the same are disclosed. In one embodiment, the device comprises a shell, at least one connection port, at least one securing feature passageway, and at least one securing feature. The at least one connection port is disposed on the multiport with the at least one connection port comprising an optical connector opening extending from an outer surface of the multiport to a cavity of the multiport and defining a connection port passageway.
