摘要： An optical subassembly comprises a micro-optical bench and a corresponding molded device submount having an optical detector, LED, or laser diode mounted thereon. The optical bench is a semiconductor wafer having one or more grooves etched therein. A submount groove is designed to receive a cooperating ridge on a bottom surface of the molded device submount so as to limit the movement of the submount on the optical bench. An optical fiber is secured in an alignment groove and secured to the optical bench. To complete the subassembly, it is only necessary to set the axial distance between the optical detector, LED, or laser diode and a distal end of the optical fiber. A fiber stop incorporated into the micro-optical bench automatically adjusts the axial positioning of the distal end of the fiber to the optical detector, LED, or laser diode. In addition, a hermetically sealed package is provided with a faceplate that is secured to the package. The faceplate is easily adapted to include various latching mechanisms that cooperate with a variety of different optical connectors.

摘要： A method and apparatus for aligning an optical fiber (120) with an optoelectronic hybrid device (112) and locking the optical fiber in the aligned position are disclosed. A fiber coated with an external layer of gold is threaded through a solder preform (130). The optical fiber (120) rests upon a ceramic substrate (104). The ceramic substrate also supports a device submount (108) that houses the optoelectronic device (112). The ceramic substrate (104) supports a resistor/heater formed of a thin film of nickel-chromium alloy (604). The resistor/heater supports a pad (609) formed of a layer of nickel (610) and a layer of gold (612). Located atop the pad (609) is the solder preform (130). Precise control of heating is provided by applying a predetermined voltage to the resistor/heater (122) for precise time periods, thereby eliminating the necessity of making temperature measurements during heating. As the resistor/heater (122) is energized, the solder preform is liquefied. An open loop search process that utilizes signal strength feedback is used to control the operation of an x-y-z micropositioning stage (328) that precisely positions an arm (306) that supports the optical fiber (120). The alignment system also includes a fixturing setup that includes a probe head (340) having multiple electrical probes (502a, 502b, 504a, 504b) and a vertical rod (506) that applies a downward force to the solder during manufacturing.

摘要： A method for providing an improved interconnection between an optical fiber and an optical package is described. The method includes inserting an end of the fiber through a feed through tube and into a main body of the optical package, a portion of the fiber proximate the end being metalized, attaching the metalized portion of the fiber within the main body of the optical package, a portion of the metalized fiber remaining within the feed through tube, inserting a stopping device into the feed through tube, melting solder within the feed through tube, in an area between the stopping device and the main body of the optical device, the area containing metalized fiber, compressing the melted solder using the stopping device, removing the stopping device from the feed through tube after the solder has solidified, and attaching a jacket associated with the optical fiber within the feed through tube.

摘要： More cost-effective fiber optic interface modules, such as fiber optic transmitter modules and fiber optic receiver modules, are provided that meet the high performance requirements demanded by avionics and other specialized applications over a wide range of temperatures and other environmental conditions. The fiber optic interface module includes a printed wiring board having a pair of outwardly extending arms that define a notch therebetween. The fiber optic interface module also includes an integrated circuit mounted upon a medial portion of the printed wiring board and an optical subassembly. The optical subassembly includes a receptacle and an optoelectronic device, such as a light source or a detector. The receptacle generally defines an internal cavity for receiving the optoelectronic device and a pair of slots proximate the internal cavity. As such, the transmitter optical subassembly can be mounted to the printed wiring board so as to be at least partially disposed in the notch defined by the printed wiring board. In this regard, the respective arm portions of the printed wiring board are preferably inserted into the pair of slots defined by the receptacle in order to permit a portion of the optical subassembly to be disposed within the notch. As such, the path length between the optoelectronic device and the integrated circuit is effectively reduced, thereby correspondingly reducing circuit parasitics and improving the performance of the fiber optic interface module. Additionally, a method of fabricating a fiber optic interface module is provided.

摘要： An apparatus comprises an optical transmitter; an optical detector configured to receive optical signals from an optical fiber; an optical splitter having a first port, a second port coupled to the optical detector by the optical fiber, and a third port coupled to the optical transmitter; and a two stage amplifier system connected to an output of the optical detector. An input surface of the optical detector may have a diameter that is substantially equal to a diameter of a core in the optical fiber. The diameter of the input surface of the optical detector reduces capacitance and reduces signal distortion. The optical splitter may be configured to receive a first optical signal at the first port. The optical splitter may be configured to send the first optical signal to the second port and send a second optical signal received at the third port to the first port.
