摘要： A microstructure switch (10, 50) having a main body (13), a moveable switching element (17), one or more membranes (26, 52) which connect the moveable switching element (17) to the main body (13) and an actuator (30) which moves the moveable switching element (17) from a first position (72) to at least one activated position (74). The membranes may be either or both of a primary membrane (26) or a secondary membrane (52). A primary membrane (26) may be used as a temporary membrane (32) which serves to position the moveable switching element (17) until it is permanently positioned by a secondary membrane (52), or by an actuator (30). At this point the temporary membrane (32) is removed. Also an optical system (100) which uses various directing components (76) in conjunction with a microstructure switch (10, 50) to direct signals (92) to various channels (86). Also a switching array (200) which includes a number of microstructure switches (10, 50) which use various directing components (76) in conjunction with a microstructure switch (10, 50) to direct signals (92) to various channels (86).

摘要： An optical switch using a refractive optical element (52) to direct a light beam in selected directions upon operation of the switch. In a preferred embodiment, the refractive optical element is an optical wedge having a first portion (67) that transmits a light beam in a selected direction, and a second portion (50) that transmits the light beam in another direction, when the first or second portions of the optical wedge are switched into the path of the light beam. The refractive optical element is less sensitive to misalignment than a reflective element, for example. In a further embodiment, the optical wedge is combined with wavelength-selective filters (118, 128) and other components to provide a channel DROP and/or ADD function with high isolation.

摘要： Optical fiber terminations requiring collimated output from single-mode fibers (SMF) have been accomplished in the past through use of graded index lens (GRIN) technology. GRIN lenses are expensive, difficult to mount and align, require adhesive bonds, and are relatively large compared to the optical fiber diameter. The use of a UV laser refractive index tunable fused multi-mode fiber as a termination collimator provides a more compact, durable, inexpensive means of coupling single-mode optical fibers to other components, even those of uneven numerical aperture. Determining the exact length required for proper collimation is avoided by utilizing a laser tuning process to adjust the refractive index of the fiber to produce required collimation. This novel composition and method comprises the use of a germanium-doped multi-mode optical fiber as a collimating termination for a single-mode optical fiber. The collimating termination fiber is normally fused to the single-mode fiber. The required length of the multi-mode fiber is estimated prior to fusing to the SMF, and the refractive index is tuned by exposure to UV radiation via a laser to produce full collimation. Embodiments of this invention include switching devices using solenoid driven shutters and movable optical prisms.

摘要： Optical switches and other similar optical configurations can comprise high-speed, high precision motors such as voice coil motors to carry out optical switching for applications such as optical signal based communication systems. These switches and configurations are expected to have switch time delays per channel that are significantly shorter than conventional optical switches. Some embodiments may have switch time delays that may be about a factor of 10 (or more) shorter than that for the conventional optical switch technology. Some embodiments may optimize optical coupling efficiency to increase the optical signal intensity transmission through optical switches and potential extend the useful life of the optical switches.

摘要： A one-sided switch for redirecting light between adjacent ports. The switch uses a moveable refractor, in combination with a lens and a stationary reflector, to redirect light from one optical port to another. In a most simple embodiment light is redirected from one output port to another by repositioning the refractor in the optical path of the light and using only a single lens for collimating and focussing the light at the reflector and about the ports, respectively.

摘要： Optic switches manipulate an optical signal that has been expanded by a collimating lens. Switching is effected by introducing a prism between collimating lenses to redirect the optical signal to an alternative lens. The prism preferably has a cross-section defining a parallelogram, so that the optical signal is reflected twice within the prism to minimize cross-sectional distortion and avoid spectral effects. A circuit provides feedback on the actual position of the relay and prism for fault detection and diagnosis.

摘要： A mechanical optical switch with a first port for holding a first optical fiber and a second port for holding a second optical fiber and a lensing element positioned in front of the first and second ports. The switch has a signal port holding a signal or input fiber which emits a light beam to be switched between the first and second fibers. The light beam propagates along a free beam path to the first lensing element and is in-coupled into the first optical fiber. The switch is equipped with a beam guiding element, such as a wedge, which can be moved in and out of the free beam path for directing the light beam to the second fiber. The wedge is designed to shift the light beam by an offset and rotate it by an angle.

摘要： Optical slip rings are disclosed which permit signals to be transferred from a rotating body to a non-rotating body without any physical contact. Fiber optic bundles are utilized to conduct light signals on one body to separate fiber optic bundles on the other body. Light is projected across a small gap from the rotating bundle to the non-rotating bundle. Other variations use multiple channels, wave guides, derotating prisms and concentric annular mirrors to achieve signal transfer. The optical slip rings can transfer any signal which may be converted to a light signal.
