Abstract: To address counterfeit problems, for example, we propose a secure, flexible, and cost-effective authentication solution that can be integrated into conventional distribution logistic systems. The proposed solution for product authentication and distribution channel validation comprises three major components: 1) machine-readable Raman-active chemical taggant; 2) a taggant reader/eraser; and 3) erasable taggants. The proposed solution is to control and validate the distribution channel by authenticating the origin of products. Authentication is accomplished by verification of distinct taggants associated with the article, such as on its label, along with other product distribution information in optical, spatial-encoding indicia, such as a barcode. The taggant information is used to identify, validate, and distinguish the origin of the source of the articles, such as goods or products. The taggant material is thereafter rendered unreadable by modifying the taggants to make obtaining the encoded information unfeasible, thereby controlling the taggants' lifecycle.

Abstract: Mounting and alignment structures for optical components allow optical components to be connected to an optical bench and then subsequently aligned, i.e., either passively or actively, in a manufacturing or subsequent calibration or recalibration, alignment or realignment processes. The structures comprise quasi-extrusion portions. This portion is "quasi-extrusion" in the sense that it has a substantially constant cross section in a z-axis direction as would be yielded in an extrusion manufacturing process. The structures further comprise at least one base, having a laterally-extending base surface, and an optical component interface. At least one armature connects the optical component interface with the base. In the preferred embodiment, the base surface is securable to an optical bench.

Abstract: A scanning optical monitoring system and method are appropriate for high speed scanning of a WDM signal band. The system and method are able to identify dropped channels or, more generally, discrepancies between the determined or detected channel inventory and a perpetual inventory for the WDM signal, which perpetual inventory specifies the channels that should be present in the WDM signal assuming proper operation of the network. The system includes a tunable optical filter (110) that scans a pass band across a signal band of a WDM signal (10) to generate a filtered signal (114). A photodetector (116) then generates an electrical signal (118) in response to this filtered signal. A decision circuit (130) compares the electrical signal to a threshold and a controller (150), which is responsive to the decision circuit, inventories the channels in the WDM signal (10).

Abstract: An optical resonator including is designed is to degrade the ability of the resonator to support suppress higher order transverse spatial modes. The inventive optical resonator forces Higher higher order transverse modes to be fundamentally unstable in the inventive optical resonator, ultimately achieving ultimately to achieving single transverse mode resonator operation. Specifically, the bounded phase deflection mirror shape or intracavity lens profile is tailored to confine the fundamental mode while rendering the higher order modes unstable. This has application in MEMS/MOEMS optical resonator devices by suppressing the side modes and increasing the side mode suppression ratio (SMSR), as well as improving SMSR tolerance to device external alignment, for example. This also has application to achieving single transverse mode operation in laser resonators, such as in semiconductor vertical-cavity surface-emitting lasers (VCSEL).

Abstract: A wavelength measurement system uses birefringent material waveplate, thereby producing a substantially sinusoidal spectral response. As a result, the responses of multiple birefringent filters can be combined to yield a filter system with a periodic frequency response that has an additive wavelength resolution that is spectrally stable. That is, the wavelength measurement system does not have regions where wavelength resolution is degraded. In one implementation, a waveplate system 112 is used, placed between two blocks of birefringent material 110 and 114 . A quadrant detector 116 is used to detect the intensities of the resulting four beams.

Abstract: A semiconductor tunable laser system includes a tunable Fabry-Perot cavity and a cavity length modulator, which controls an optical length of the cavity at least over a distance corresponding to the spacings between the longitudinal modes of the laser cavity. Thus, the tunable Fabry-Perot cavity allows the laser cavity to have gain at the desired wavelength of operation while the cavity length modulator tunes the cavity length such that a longitudinal cavity mode exists at the desired wavelength of operation. Also, in one embodiment, a wavelength locker system is further provides that has a differential wavelength filter, e.g., stepped etalon, and a multi-element detector, e.g., a quad-detector. The controller then modulators the Fabry-Perot cavity to control the wavelength in response to the signal received from the multi-element detector.
