摘要： An apparatus (1) that is capable of a first stable configuration and a second stable configuration is disclosed. The bistable mechanism (10) has a leg (30, 32) that is coupled on one end by a base member (22, 24) and on the other end by a shuttle (20). The leg (30, 32) stores potential energy as it is deflected. The potential energy stored in the leg (30, 32) has a maximum potential energy position with a low potential energy position on either side of the maximum. An apparatus and method are also disclosed for a latching mechanism (910) and the associated method. The latching mechanism (910) is comprised of a grasping member (932), a lock slider (928), and a detent slider (916). These three members (916, 928, 932) operate together to induce a locked configuration and an unlocked configuration by actuating the lock slider (928) in a single direction.

摘要： An article comprising a light-actuated photonic switch is disclosed. The light-actuated photonic switch advantageously includes a photogenerator that powers a micro-electromechanical systems (MEMS) switch having very low voltage requirements. The MEMS switch is operable to move a reflector into or out of a path of an optical signal travelling between two waveguides. Since the MEMS switch has such low voltage requirements, a long wave photogenerator, which generates relatively low voltages, can be used. As long wavelength light experiences relatively little attenuation in optical fiber, active lightwave circuits incorporating the present light-actuated photonic switch can have very long fiber runs to remote nodes.

摘要： A fiber optic switching system which includes an optical switch having a movable actuator (20) and a light fiber (100) coupled to the actuator (20) which terminates at an end surface thereof for conducting light from a light source (88, 89) to the optical switch mechanism (20). A flexible reflective film (11) whose reflectivity is conditioned to provide at least two different reflective surfaces (11, 13, 15) is positioned such that an end surface of the actuator (20) abuts the film (11) throughout its movement from one position to another. A detector (84) detects light reflected from the film (11). The actuator (20) is movable so as to direct light from the light fiber (100) from the one reflective surface of the film (11) to another fiber (102) and the detector (84) detects light reflected from the film (11) so as to determine which reflective surface of the film (11) from which light has been reflected.

摘要： An optical switch having two spherical or elliptical corner-reflecting surfaces (5c) provided in a light-conducting member (5, 10), a shutter (8) to open and close a light path between the corner-reflecting surfaces, and focusing lenses (5b) to focus the incident beam from an emitting optical fiber (3) and to focus the emitting beam from the light-conducting member to a primary receiving optical fiber (4). Because almost all the beam transmitted through the light-conducting member is focused at one point (A) in an air gap (5d) in which the shutter moves, the optical switch can transmit the beam with high efficiency without leakage to the outside, and a small stroke of the shutter is sufficient to completely transmit or stop the beam. In another similar optical switch having a reflecting surface (11a) at the tip of the shutter (8) for inclining the beam, as well as having a secondary receiving optical fiber (12) aligned with the path of the inclined beam, the beam is switched to be transmitted to the primary receiving optical fiber (4) or to the secondary receiving optical fiber (12) according to the position of the shutter. Thus, the ON/OFF state of the optical switch can be indicated, or a transfer-type optical switch can be obtained by using the secondary receiving optical fiber as well as the primary receiving optical fiber as switching circuits.
摘要翻译：一种光开关，其具有设置在光导构件（5,10）中的两个球形或椭圆形角反射表面（5c），打开和关闭角反射表面之间的光路的快门（8），以及聚焦透镜（5b）聚焦来自发射光纤（3）的入射光束并将来自光导构件的发射光束聚焦到主接收光纤（4）。因为通过光导构件传播的光束几乎全部聚焦在光闸移动的气隙（5d）中的一个点（A）处，所以光开关能够以高效率传输光束而不泄漏到外部，并且快门的小行程足以完全传送或停止光束。在另一种类似的光开关中，在光闸倾斜的快门（8）顶端具有反射表面（11a），并且具有与倾斜光束路径对齐的次级接收光纤（12），该光束是根据快门的位置切换到主接收光纤（4）或次接收光纤（12）。因此，可以指示光开关的开/关状态，或者通过使用辅助接收光纤以及主接收光纤作为开关电路，可以获得转移型光开关。

摘要： A switch (10) for controlling the transmission of light from a first optical fiber (F1) to at least at second optical fiber (F2) or from a single bidirectional optical fiber (F1) back to itself includes a housing (22) having a spherical concave reflector (40) mounted therewithin. Fiber mounting means (M) is provided for mounting optical fiber(s) at a predetermined location within the housing such that at least a portion of a beam of light emanating from the end face of one fiber propagates along an incidence path (52) toward the reflector from which it is reflected by the curved concave reflector along a predetermined reflectance path (54). A light interrupter (60) is mounted within the housing for switchable movement between a light transmissive state and a light interruptive state. A light absorbing member (76) is positioned such that residual light reflected from the light interrupter is directed toward and absorbed by the light absorbing member. A switch presence indicator (70) for providing an indication that the light interrupter is disposed in the interdiction position may also be included.

摘要： A micromachined device (50) for selectively switching an optical fiber (48) between a first and a second position includes a working leg (88) that undergoes a greater degree of thermal expansion than a second leg (86) with the conduction of an electrical current through the two legs. In a preferred embodiment, the working leg has a cross-sectional area that is less than that of the second leg, thereby presenting a greater electrical resistance to the current flow. The legs are each fixed to a substrate (62) at first ends and are interconnected at second ends that are free to move relative to the substrate. The difference in electrical resistance provides a differential in thermal expansion, as the working leg lengthens to a greater degree than the second leg. The working leg deforms the second leg and the optical fiber is pressed into a second position until current flow is terminated. In another embodiment, the differential in thermal expansion is created by ensuring that the second leg has less thermal isolation from the substrate than the thermal isolation of the working leg from the substrate.
