    Abstract: A system and method for fast peak finding in an optical spectrum prioritizes the information it first generates and how the information is then forwarded from the system to a host computer, for example. A spectrum detection subsystem generates a spectrum of an optical signal. An analog-to-digital converter converts the spectrum into sample data. Finally, a data processing subsystem first detects the spectral locations of peaks in the spectrum using the sample data and then uploads the peak information to a host computer before performing processing to determine the shapes of the peaks and/or noise information for the optical signal, for example. The system is thus able to quickly find some information, such as whether or not channels or carriers are present, at what frequency the carriers are operating, and the carriers' power level, and send this information to the host computer. In contrast, information concerning spectral shape or the noise floor is sent later in time.

    Abstract: A dynamic optical spectral filter is implemented in a microelectromechanical system (MEMS). It comprises a frame. An array of mirrors is provided on a first portion of the frame, along with a second array of adjustment mirrors on a second portion of the frame. An array of variable beam splitters is provided on a middle portion of the frame, between the first array and the second array. Finally, to provide the filter functionality, optical delays are disposed in beam paths between the first mirror array the second mirror array. These elements are used to produce multiple Mach-Zehnder interferometers, such as cascaded or series interferometers. Implementations have advantages associated with speed of operation and can have polarization isotropy.

    Abstract: Tabs or stops are integrated into a membrane structure to prevent its snapdown. Features comprising two surfaces separated by a distance equal to the maximum desired range of movement are produced. When the two surfaces contact, the motion of the structure is arrested or greatly diminished by increasing its rigidity. For an electrostatically actuated MEMS structure, these features can be used to limit the range of motion such that pull-in or snapdown is avoided, greatly enhancing the reliability of the device. One key design feature is that the two contacting surfaces are maintained at the same electrical potential avoiding problems associated with electrostatic cavity discharge.

    Abstract: An integrated swept wavelength tunable optical source uses a narrowband filtered broadband signal with an optical amplifier and self-tracking filter. This source comprises a micro optical bench, a source for generating broadband light, a tunable Fabry Perot filter, installed on the bench, for spectrally filtering the broadband light from the broadband source to generate a narrowband tunable signal, an amplifier, installed on the bench, for amplifying the tunable signal. The self-tracking arrangement is used where a single tunable filter both generates the narrowband signal and spectrally filters the amplified signal. In some examples, two-stage amplification is provided. The use of a single bench implementation yields a low cost high performance system. For example, polarization control between components is no longer necessary.

    Abstract: The present invention concerns the use of hybrid metal-dielectric optical coatings as the end reflectors of laser cavities and/or in the mirror structures used in other optical resonators, such as Fabry-Perot tunable filters, along with the use of such Fabry-Perot tunable filters in wavelength swept sources such as lasers. Hybrid metal-dielectric optical coatings have reflectivity spectra that can be broader than pure dielectric coatings, offer optical reflectivities higher than metal, as high as pure dielectric coatings, eliminate mirror transmission that can cause parasitic light reflections, and use fewer layers and thus have lower mass and higher mechanical resonant frequency for movable mirror applications An important characteristic of these coatings concerns the non-reflected light. Pure dielectric coatings offer high reflectivity, while the non-reflected portion of the light is transmitted by the coating to the substrate, for example. When metal is added to the optical coating, the non-reflected portion of the light is absorbed by the metal and is not transmitted to the substrate or outside the cavity. Hybrid metal-dielectric coatings have broader and more uniform spectral reflection. Tunable lasers with performance enhanced by the hybrid metal-dielectric coatings can be used in optical coherence tomography and spectroscopic analysis applications.
