A chip may include a first substantially planar isolation layer with a first surface and a second surface opposite the first surface. The chip may include a first substantially planar conduction layer with a first surface positioned adjacent to the second surface of the first isolation layer and a second surface opposite the first surface. The chip may include a second substantially planar isolation layer with a first surface positioned adjacent to the second surface of the first conduction layer and a second surface opposite the first surface. The chip may include a second conduction layer etched on the second surface of the second isolation layer. The second conduction layer may include an anode trace, a cathode trace, and an optical transmitter positioned on the cathode trace. The chip may include one or more vias through the second isolation layer electrically coupling the anode trace with the first conduction layer.

Chip on carrier

A resistance weldable cover for an OSA may include multiple walls, one or more supports, and an opening disposed in one of the walls. The walls may define an interior cavity within the walls. The one or more supports may extend from one or more of the walls. Each of the one or more supports may be weldable to a heat sink stiffener. The opening may be sized and shaped to receive at least a portion of a barrel such that optical signals are transmittable between the interior cavity and the barrel.

Horizontal flex circuit with resistance weldable cover

In one embodiment, an optoelectronic assembly may include at least one transmitter or at least one receiver, a sleeve, a housing, a fiber stub, and a receptacle. The sleeve may define a sleeve opening sized and shaped to receive an optically transmissive portion of an optical fiber. The housing may define a housing cavity at least partially enclosing the transmitter or the receiver. The housing may include a lens port defining a lens port opening. The fiber stub may be positioned at least partially in the sleeve opening and the lens port opening. The receptacle may define a receptacle opening. The lens port, the sleeve and the fiber stub may be positioned at least partially in the receptacle opening.

Connector assemblies for optoelectronic modules

A tunable laser transmitter configured in a small package subassembly coupled to a printed circuit board. The tunable laser transmitter includes a housing with a volume formed by exterior walls. An electrical input interface is positioned at the first end of the housing. A first and a second optical output interface is positioned at the second end of the housing, the first output being configured to transmit a modulated optical beam, and the second output configured to transmit a cw beam to the local oscillator of an external receiver.

Small packaged tunable laser transmitter

A laser assembly and a method for manufacturing the same are provided according to embodiments of the present disclosure. The laser assembly () may comprise a first plate () having first projections (); a printed circuit board assembly () including a printed circuit board () having first openings () and a laser module () thereon, and a second plate () having second projections (). The printed circuit board assembly () can be retained between the first plate () and the second plate () by the first projections () and the second projections (). The laser assembly may further comprises a first pad () provided between the laser module () and the first plate () and/or a second pad () provided between the laser module () and the second plate (). Any of the first pad () and the second pad () may be adaptable to be compressed, and adaptable to hold the laser module () or to hold the laser module () and to dissipate the heat from the laser module ().
