Abstract: An optical package includes one or more MEMS mirrors to provide alignment between internal optical components and the signal port(s) on the package (where one or more ports may include optical fiber attachments). Once the components are placed in the package, an electrical signal is used to adjust the deflection profile of the appropriately positioned MEMS mirror(s) until maximum coupling between the internal components and the fibers/ports is obtained. Advantageously, if later signal degradation occurs due to, for example, subsequent physical misalignment of the internal components, corrective electrical signal can be sent to the MEMS mirror(s) to provide correction and re-alignment without having to open the package and physically move the components.

Abstract: An optoelectronic device comprising a laser and a lens for generating collimated light, a locker including an etalon for wavelength locking the collimated light, a first thermoelectric cooler coupled to the laser, and a second thermoelectric cooler coupled to the locker, wherein the first and second thermo-electric coolers arc independently controlled and the second thermo-electric cooler provides for temperature tuning of the etalon.

Abstract: A twin-Thermoelectric cooler design including two independent thermoelectric coolers sharing the same base (hot side ceramic plate). People familiar with the art understand that the number of independent TEC sharing the same base is not limited to two. Depending on application needs any number of TECs can be constructed on the same base and be controlled independently.

Abstract: This invention provides a holder for releasably engaging a plug component of an optoelectronic device to facilitate automated testing of the optoelectronic device. The plug component of the optoelectronic device has a body and a flange extending radially outwardly from that body. The holder defines a recess configured to releasably engage the body of the plug to resist movement of the plug with respect to the holder in a direction transverse to the axis of the plug's body. The holder also includes a surface oriented for contact with the flange of the plug to resist movement of the plug with respect to the holder in a direction along the axis of the plug's body. A corresponding method is also provided.

Abstract: A support assembly for retaining a laser module of the type having a solid state laser, an optical connector and an optical fiber extending between the laser and the optical connector. The support assembly includes a baseplate having a top surface and a bottom surface. A removable spool extends upwardly from the top surface of the baseplate, wherein the spool is sized to have the optical fiber wound therearound. A laser receptacle disposed on the top surface of the baseplate. The laser receptacle is sized to receive the solid state laser in a first predetermined position and orientation. A connector holder is also disposed on the top surface of the baseplate. The connector holder receives and retains the optical connector at a second predetermined position and orientation.

Abstract: A package housing that is used to retain a wound spool and prevent a wound element from falling away from the spool. The housing includes a base segment having a hub disposed thereon and a recessed area surrounding the hub. The hub is sized to pass into the bottom end of the spool, thereby causing the spool to rest in the recessed area of the base segment of the housing. A cover segment is provided for covering the base segment of the housing and the spool. As a result, the spool becomes interposed between the base segment and the cover segment of the housing. A plurality of feed-through ports are defined between the base segment and the cover of the housing. The first end and the second end of the wound flexible element extend through two of the feed-through ports to points external of the housing.

Abstract: A raised photodetector constructed to define an open channel extending between opposite edges of the photodetector and dimensioned for permitting light from laser to pass therethrough. The photodetector has a light-collecting region disposed in an outward facing wall recessed within the channel for collecting light from the laser.

Abstract: An assembly that assists in the winding of an optical fiber of a laser module around a spool. The assembly contains a spool support that holds the spool as the optical fiber is wound around the spool. The spool support has a top surface with opposing side edges. The top surface of the spool support has a periphery, wherein the top surface of the spool support is beveled between its peripheral edge and the groove. The presence of the bevel helps to guide the optical fiber onto the spool as the optical fiber is wound around the spool. A generally circular groove is disposed in the top surface of spool support, wherein the groove at least partially intersects the opposing side edges of the top surface. As a result, when the spool is attached to the spool supports, opposite sides of the spool protrude beyond the sides of the spool support.
