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.
摘要翻译：公开了一种用于使光纤（120）与光电混合设备（112）对准并将光纤锁定在对准位置的方法和设备。涂覆有外层金的纤维穿过焊料预成型件（130）。光纤（120）位于陶瓷基板（104）上。陶瓷基板还支撑容纳光电子器件（112）的器件底座（108）。陶瓷基板（104）支撑由镍 - 铬合金薄膜（604）形成的电阻器/加热器。电阻器/加热器支撑由镍层（610）和金层（612）形成的焊盘（609）。位于焊盘顶部（609）上的是焊料预制件（130）。通过向电阻器/加热器（122）施加预定的电压来提供精确的时间段来提供加热的精确控制，从而消除了在加热期间进行温度测量的必要性。当电阻/加热器（122）通电时，焊料预制件被液化。使用利用信号强度反馈的开环搜索过程来控制精确定位支撑光纤（120）的臂（306）的x-y-z微定位台（328）的操作。对准系统还包括固定装置，其包括具有多个电探针（502a，502b，504a，504b）的探针头（340）和在制造期间向焊料施加向下的力的垂直杆（506）。
