Abstract: A method and apparatus for implementing a colorless polarization independent Mach-Zehnder-interferometer (MZI)-based tunable dispersion compensator (TDC) that has only three MZI stages (two in a reflective MZI-TDC ) and two adjustable couplers which are responsive to one control voltage, making it compact, low power, and simple to fabricate, test, and operate. Polarization independence is obtained by using a half-wave plate positioned across the midpoints of the two path lengths of middle stage MZI of the three stage MZI-TDC and by using a quarter-wave plate in front of a reflective facet of the reflective MZI-TDC. A cascaded MZI-TDC arrangement with also only a single control is formed by cascading two MZI-TDC arrangements and driving all adjustable couplers with the same control signal.

Abstract: Spot-size conversion for interfacing a first optical element having a higher refractive index to a second optical element having a lower refractive index is achieved through the use of two optical star couplers coupled to each other through a plurality of optical paths embedded in a planar waveguide. The beam from the high refractive index element is introduced into a high numerical aperture (NA) star coupler, which directs the beam through a plurality of optical paths to a second star coupler with a lower numerical aperture than the first star coupler so that its output spot-size is larger. The output port of the second star coupler is interfaced to the lower refractive index element. Wavelength selection can be provided by making non-zero path-length differences between adjacent optical paths between the two star couplers. Wavelength tunability can be provided by including phase shifters in the paths between the two star couplers to alter the effective optical lengths of the paths to selectively produce the desired phase interference pattern at the desired wavelength.

Abstract: A method and apparatus are disclosed for selectively passing or blocking an optical signal using an opaque or reflective shutter that is selectively positioned in or out of the light path. The disclosed wavelength blocker can be employed to filter input wavelength-division multiplexed (WDM) signal comprised of N wavelength channels, where a mechanical shutter array selectively passes each of the N wavelength channels. Each mechanical shutter may be controlled, for example, by a micromachine control element that physically lifts the shutter into or out of the lightpath. The disclosed wavelength blockers may be utilized in wavelength-selective cross connects, as well as other optical devices. In an exemplary wavelength-selective cross connect, an array of mirrors are employed in a planar waveguide having two sets of waveguide gratings intersecting at an angle. The mirrors and waveguide gratings are positioned such that if the mirror for a given channel is up (removed from the light path), then that channel passes across the device and exits the corresponding output port (bar state), otherwise the light is reflected by the mirror and exits the opposite output port (bar state).

Abstract: A method and apparatus are disclosed for adjusting the phase of an optical signal by varying the path length of the optical signal using one or more moveable mirrors. The phase adjustment techniques of the present invention may be employed in various optical devices, including 1×n optical switches. The position of the mirrors may be controlled, for example, using micromachined control elements that physically move the mirror along the lightpath. An exemplary 2-by-2 optical switch includes two waveguides configured to include a coupler region. A mirror is positioned at the output of each waveguide. The position of at least one of the mirrors may be adjusted along the optical path and the mirrors reflect the light exiting from the end of the waveguides back into the same waveguide after an adjustable phase delay due to the round trip through an adjustable air gap between the waveguides and corresponding mirrors. A received optical signal is split in the coupler region into two generally equal components and the phase of at least one component of the optical signal is adjusted by controlling the relative position of the mirrors. The optical components are then recombined and the optical signal appears at the appropriate output port of the optical switch. The present invention may also be applied in wavelength selective optical switches that support multiple optical channels. A number of techniques are also disclosed for fabricating optical devices in accordance with the present invention.

Abstract: A hang tag is disclosed. The hang tag has first and second surfaces, which are preferably planar. A slot is defined between the first and second surfaces. Desirably, the slot extends at least about 0.25 inches in one direction and at least about 1 inch in another direction. Also disclosed is a method and an apparatus for automatically applying a hang tag to an elongated object (e.g., an electrical cord such as a cord set), with a machine that is suitable for applying a securement strap to an object. The method includes providing a hang tag having a slot therein. The hang tag is aligned with the machine so that when the securement strap is ejected from the machine, it passes through the slot, forms a loop around the elongated object, and is tensioned around the object. As such, the securement strap serves to attach the hang tag to the elongated object in a stationary manner.
