Abstract: An external cavity laser has a mirror-based resonant tunable filter, such as a Fabry Perot tunable filter or Gires-Tournois interferometer tuning element, with the tunable filter being preferably used as a laser cavity mirror. A mirror-based resonant tunable filter is selected in which the spectral response in reflection has an angular dependence. A tilt scheme is used whereby by selecting an appropriate angle between the filter's nominal optical axis and the cavity optical axis, a narrowband peak spectral reflection is provided to the laser cavity. This tunable narrowband spectral reflection from the filter is used to lock and tune the laser output wavelength.

Abstract: An optical power control system for a semiconductor source spectroscopy system controls power fluctuations in the tunable signal (210) from the spectroscopy system (100) and thus improves the noise performance off the system. This general solution has advantages relative to other systems that simply detect reference power levels during the scan and then correct the detected signal after interaction with the sample by reducing the requirements for coordinating the operation of the sample detectors and power or reference detectors. The spectroscopy system (100) comprises a semiconductor source (200, 610, 622) and a tunable filter (612). The combination of the semiconductor source (200, 610, 622) and tunable signal (210) illuminate a sample (10) with a tunable signal (210), being tunable over a scan band (510). The power control system comprises an amplitude detector system (320, 322) for detecting the power of the tunable optical signal (210) and power control system (410, 411, 318) for regulating the amplitude of the tunable optical signal (210) in response to its detected power.

Abstract: An optical resonator including is designed is to degrade the ability of the resonator to supportsuppress 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 achievingultimately 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 process for assembling micro-optical systems, such as optoelectronic and/or fiber optic components (25, 35) uses solder self-alignment to achieve a coarse, passive alignment of optical components (25, 35) relative to the optical bench (5). The fine, final alignment is performed using plastic deformation of the optical components (25) to thereby improve the alignment of the optical components (25). As a result, the sub-micrometer alignment accuracies are attainable, if required.

Abstract: A micro-optical train manufacturing process includes a step of characterizing the position of optical components (114) on an optical bench (130), typically using a metrology system. These optical components (114) are then aligned with respect to each other in a passive alignment step (250) based on data from the metrology system and optical system design information. As a result, a subsequent active align process (260) can be avoided in some situations, or if a subsequent active alignment process (260) is performed, the time required for that active alignment process (260) can be reduced because of this initial metrology-based passive alignment step (250).

Abstract: An optical switch device includes a rolling shutter or membrane attached at one of its edges to a substrate near an optical port in the substrate. The rolling shutter can assume one of two states. In a first closed state, the membrane is uncoiled onto the substrate over the port such that light directed at the port impinges on the shutter. In a second open state, the membrane is rolled up away from the port such that light directed at the port impinges on the port. In one embodiment, a mirror is formed on the membrane such that when the membrane is in the closed state over the substrate, light directed at the port is reflected by the mirror. In one configuration, the optical port includes a hole or aperture such that light passed through the port without interference. The device can include a latch electrode the far end of the membrane such that when it is rolled out, it can be held in position by a latching voltage applied across the latch electrode and the substrate. Slits can be formed in the membrane to keep the mirror flat by relieving strain in the membrane and to allow gases in proximity to the device to pass through the membrane as it is activated. The shutter can include dimples to minimize the area of contact between the membrane and the substrate to reduce the probability of the two sticking together. The attachment edge of the membrane can be made shorter than its width to reduce distortions in the membrane to keep the mirror flat. A raised annular rim can be provided around the port such that when the shutter is held down over the port it is pulled taut and flat over the rim. This feature is also used to maintain flatness in the mirror. The switch device can be used as part of an array of optical switches.

Abstract: An alignment structure (100) maintains an optical fiber in a bore (113). The structure is fixed on a bench and is passively or actively aligned with a light source. Then the structure may be welded or soldered to the optical bench whereby the alignment may suffer due to heat transfer. To correct this, the alignment structure can be plastically deformed to correct the alignment after the components have been fixed. The alignment structure has a substantially constant cross section in a z-axis direction as well as flexible links in order to allow displacements orthogonal to the optical axis. This movements will be initiated by seizing the component with a micro-positioner at a handle (136) and displacing it over the elastic limit to achieve permanent deformation.

Abstract: An optical probe for emitting and/or receiving light within a body comprises an optical fiber that transmits and/or receives an optical signal, a silicon optical bench including a fiber groove running longitudinally that holds an optical fiber termination of the optical fiber and a reflecting surface that optically couples an endface of the optical fiber termination to a lateral side of the optical bench. The fiber groove is fabricated using silicon anisotropic etching techniques. Some examples use a housing around the optical bench that is fabricated using LIGA or other electroforming technology. A method for forming lens structure is also described that comprises forming a refractive lens in a first layer of a composite wafer material, such as SOI (silicon on insulator) wafers and forming an optical port through a backside of the composite wafer material along an optical axis of the refractive lens.
