摘要:
An opto-electronic module has a platform and an optical sub-unit. The platform has a trough structure defined on a surface of the platform and the trough structure is configured to transmit an optical beam through the trough structure. The electrical sub-unit is coupled to the trough structure. The sub-unit is configured to mate with the trough structure to provide a chosen alignment to emit, operate on or receive the optical beam.

An optoelectronic device is mounted on a planar substrate in electrical connection with solder bumps adjacent an edge of the substrate and connection to a lead frame is made by loading the edge of the substrate on a lead frame support with lead frame conductors in engagement with the solder bumps and applying heat to melt the solder.
摘要:
An assembly of first and second optical components, the first component comprising a package (11) within which is contained an optical emitter (35) and the second component comprising a package (19) within which is contained an optical processing device (18). One part (30) of a two part connector is mounted on a wall (16) of the first component package (11) and has means defining an optical path optically coupled to the emitter. The other part (32) of the two part connector is mounted on a wall (31) of the second component package (19) and has means defining an optical path optically coupled to the processing device (18). The two connector parts are directly interengageable. The optical path defining means of the one connector part (30) comprises a beam expander (36) arranged to receive an optical signal from the emitter (35) and a lens (38) arranged to focus the expanded beam on to one end of an optical fibre stub (39) positioned co-axially and at least partially within the one connector part (30). The optical path defining means of the other connector part (32) includes a fibre (44) held co-axially within the other connector part for aligned abutting engagement with the stub (39) of the one connector part. The fibre (44) of the other connector part optically communicates with the processing device (18).
摘要:
An encapsulated optocomponent comprises an optocomponent assembly (14) having an optical interface at one side, which comprises guide pins (27) for positioning a connected optical component or optical connector. The assembly (14) is attached to the outermost portion (10) of a flexible tongue (9), which is an integral part of a dielectric carrier such as a polymer carrier (7). On or inside the carrier and the tongue (9) thereof electrical conductive paths are arranged which are connected to the optoassembly (14) and to electrical driver circuits in a driver circuit assembly (13), so that the carrier also has the function of a conventional lead frame. The entire device is moulded into an encapsulating plastic material (25). In the moulding operation the positioning of the optoassembly in an accurately determined position and the retainment thereof in this position is facilitated by the flexibility of the tongue (9), not being affected for example by the fact that an injected encapsulating material may possibly displace the significantly larger driver circuit assembly (13) and its attachment area (5) on the carrier (7). This construction can also allow that only the optoassembly is encapsulated, the driver circuit assembly being protected in some other way, so that the flexible tongue (9) is exposed. This design can facilitate the accurate positioning of the optocomponent assembly on a circuit board.
摘要:
An optical module and a method to assemble the optical module are disclosed. The optical module comprises a laser unit, a modulator unit, and a detector unit each mounted on respective thermo-electric coolers (TECs). The modulator unit is arranged on an optical axis of the first output port from which a modulated beam is output, the modulator unit modulating the continuous wave (CW) beam output from the laser unit. On the other hand, the laser unit and the detector unit are arranged on another optical axis of the second output port from which another CW beam is output. The method to assemble the optical module first aligns one of the first combination of the laser unit and the modulator unit with the first output port and the second combination of the laser unit and the detector unit, and then aligns another of the first combination and the second combination.
摘要:
An optical module that processes an input optical signal and outputs a processed optical signal is disclosed. The optical module provides a housing and an optical processing device in the housing. The housing provides an optical input port and an optical output port in a first wall thereof in side-by-side arrangement. A third wall of the housing only provides RF terminals. Second and fourth walls of the housing provide DC terminals. Electrical connection between the DC terminals with DC pads on the device is realized through a wiring substrate whose top avoids an optical path from the optical input port to the input port of the device.
