20120301073 | INTEGRATED SILICON PHOTONIC ACTIVE OPTICAL CABLE COMPONENTS, SUB-ASSEMBLIES AND ASSEMBLIES - Integrated silicon photonic active optical cable assemblies (ACOAs), as well as sub-assemblies and components for AOCAs, are disclosed. One component is a multifiber ferrule configured to support multiple optical fibers in a planar array. The multifiber ferrule is combined with a flat top to form a ferrule sub-assembly. Embodiments of a unitary fiber guide member that combines the features of the multifiber ferrule and the flat top is also disclosed. The ferrule sub-assembly or the fiber guide member is combined with a photonic light circuit (PLC) silicon substrate with transmitter and receiver units to form a PLC assembly. The PLC assembly is combined with a printed circuit board and an electrical connector to form an ACOA. An extendable cable assembly that utilizes at least one ACOA is also described. | 11-29-2012 |
20130266259 | MONOLITHIC BEAM-SHAPING OPTICAL SYSTEMS AND METHODS FOR AN OCT PROBE - Monolithic beam-shaping optical systems and methods are disclosed for an optical coherence tomography (OCT) probe that includes a transparent cylindrical housing having asymmetric optical power. The system includes a transparent monolithic body having a folded optical axis and at least one alignment feature that supports the end of an optical fiber adjacent an angled planar end wall. The monolithic body also includes a total-internal reflection surface and a lens surface that define object and image planes. Light from the optical fiber end traverses the optical path, which includes the cylindrical housing residing between the lens surface and the image plane. Either the lens surface by itself or the lens surface and the reflective (eg, TIR) surface in combination are configured to substantially correct for the asymmetric optical power of the cylindrical housing, thereby forming a substantially rotationally symmetric image spot at the image plane. | 10-10-2013 |
20140247454 | POWER TRANSMISSION AND SENSING DEVICE - A torque transmission assembly comprising: (i) an optical fiber coupled to an optical sensing component and capable of rotating and translating the optical sensing component and of transmitting light to and from the optical sensing component; and (b) an annular structure surrounding the optical fiber, the annular structure in conjunction with said optical fiber transmits torque from a rotating component to the optical sensing component, wherein the annular structure does not include a steel wire torque spring. | 09-04-2014 |
20140247455 | OPTICAL COHERENCE TOMOGRAPHY ASSEMBLY - An OCT assembly comprising: (a) a light transmissive rod having a first end, a second end, and a central axis; and a refractive surface adjacent to the second end; (b) a housing surrounding the OCT probe component; the housing having a tubular body with the window situated over the refractive surface, said tubular body having a surface wherein said surface of said tubular body has a coefficient of friction being less than 0.3; (c) an optical fiber connected to the OCT probe component; (d) an annular structure surrounding said optical fiber and capable of translating and rotating the OCT probe component. | 09-04-2014 |
20140346693 | METHODS OF FORMING A TIR OPTICAL FIBER LENS - Methods of forming a total-internal-reflection (TIR) optical fiber lens are disclosed. The methods include heating an end of an optical fiber with a defocused infrared laser beam to form a bulbous tip having a curved outer surface that defines a lens surface. The bulbous tip is laser cleaved to define a TIR facet. Light traveling in the fiber diverges at an effective fiber end and is reflected by the TIR facet through the lens surface to form an image at an image plane. | 11-27-2014 |
20150025369 | HOUSING FOR THE OCT PROBE, OCT PROBE ASSEMBLY, AND A METHOD OF MAKING SUCH ASSEMBLY - According to some embodiments a housing for the OCT comprises: (a) a tubular body with an inner diameter of less than 5 mm (for example less than 2 mm, and in some embodiments not greater than 1.5 mm), a first end, a second end; and a window formed in the tubular body closer to the second end than to the first end, displaced from the second end, and framed by a portion of the tubular body, wherein the window has a width w.
