摘要： A fiber amplifier having two erbium doped fiber coils and a pump laser diode optically coupled, through a fiber array, to a planar lightwave circuit, is described. A photodetector array, a multiport free-space optical isolator, and a strip of thin-film gain flattening filter are attached to a side surface of the planar lightwave circuit, which has a tunable optical power splitter for variably splitting the optical pump power for the laser diode between the two erbium doped fiber coils, and variable tilters for correcting the gain tilt of the amplifier. The variable splitter and the tilters are thermally tunable Mach-Zehnder interferometers.

摘要： The present invention relates to a wavelength switch including two switching stages. A single actuation array of reflecting elements of a first switching stage routes sub-beams at different wavelength bands to a plurality of actuation arrays of reflecting elements of a second switching stage. Each second-stage actuation array routes sub-beams to a group of output ports associated with that second-stage actuation array. Advantageously, the sub-beams are redirected from the first switching stage to the second switching stage by a reflecting relay assembly, without being combined or coupled into fibers.

摘要： The present invention relates to an articulated micro-electro-mechanical (MEMS) device, which is constructed in such a way as to enable several of the devices to be closely packed together, i.e. high fill factor, for redirecting specific wavelengths of light from a dispersed optical signal to different output ports. The articulated MEMS device includes multiple pivotally connected sections that are pivotable about two perpendicular axes for limiting the amount of dynamic cross-talk as the device is rotated between different positions.

摘要： A micro-electro-mechanical (MEMS) mirror device for use in an optical switch is disclosed. A “piano”-style MEMs device includes an elongated platform pivotally mounted proximate the middle thereof by a torsional hinge. The middle portion of the platform and the torsional hinge have a combined width less than the width of the rest of the platform, whereby several of these “piano” MEMs devices can be positioned adjacent each other pivotally mounted about the same axis with only a relatively small air gap therebetween. In a preferred embodiment of the present invention the spacing between electrodes is increased without effecting the fill factor of the mirrors by interlacing two sets of tilting platforms, whereby the reflecting portions of both sets of tilting platforms are adjacent one another, while the non-reflecting portions of adjacent platforms are remote from each other.

摘要： A control system is designed to control an optical cross-connect having a switch core defined by first and second independently movable beam deflectors capable of selectively defining an optical path between a pair of ports of the optical cross-connect. An optical element having optical power is arranged in a propagation path of light beams between the first and second beam deflectors. The control system includes a pilot light source, an optical sensor associated with each beam deflector, and a feedback path. The a pilot light source inserts a pilot light into the switch core colinearly with live traffic. The optical sensor detects a predetermined geometric property of the pilot light emerging from the switch core. This predetermined geometric property is unambiguously associated with an angular position of the associated beam deflector. The feedback path actively controls a position of the associated beam deflector based on the detected geometric property.

摘要： A multicast optical switch uses a diffractive bulk optical element, which splits at least one input optical beam into sub-beams, which freely propagate in a medium towards an array of directors, such as MEMS switches, for directing the sub-beams to output ports. Freely propagating optical beams can cross each other without introducing mutual optical loss. The amount of crosstalk is limited by scattering in the optical medium, which can be made virtually non-existent. Therefore, the number of the crossover connections, and consequently the number of inputs and outputs of a multicast optical switch, can be increased substantially without a loss or a crosstalk penalty.

摘要： A MEMS arrangement is provided that has a top plane containing a rotatable element such as a mirror. There is a middle support frame plane, and a lower electrical substrate plane. The rotatable element is supported by a support frame formed in the middle support frame plane so as to be rotatable with respect to the frame in a first axis of rotation. The frame is mounted so as to be rotatable with respect to a second axis of rotation. Rotation in the first axis of rotation is substantially independent of rotation in the second axis of rotation.

The middle portion of the platform and the torsional hinge have a combined width less than the width of the rest of the platform, whereby several of these “piano” MEMs devices can be positioned adjacent each other pivotally mounted about the same axis with only a relatively small air gap therebetween. In a preferred embodiment of the present invention specially designed for wavelength switching applications, a greater range of arcuate motion for a mirror mounted thereon is provided by enabling the platform to rotate about two perpendicular axes. The MEMs mirror device according to the preferred embodiment of the present invention enables the mirror to tilt about two perpendicular axes, by the use of an “internal” gimbal ring construction, which ensures that a plurality of adjacent mirror devices have a high fill factor, without having to rely on complicated and costly manufacturing processes.
