  • Patent number: 11745454
    Abstract: The present disclosure relates to methods of forming a fiber optic core, and a fiber optic component with a highly uniform cladding covering the fiber optic core. In one microfabrication process a first sacrificial tubing is provided which has a predetermined inner diameter. A quantity of a curable polymer is also provided. The first sacrificial tubing is at least partially filled with the curable polymer. The curable polymer is then cured. The first sacrificial tubing is then removed to produce a finished fiber optic core. Additional operations may be performed by which the fiber optic core is placed inside a thermoplastic tubing, which is itself placed inside a sacrificial heat shrink. Heat is applied to reflow the thermoplastic tubing around the fiber optic core, thus forming a highly uniform thickness cladding. When the sacrificial heat shrink tubing is removed a finished fiber optic component is present.

  • Patent number: 11691378
    Abstract: The present disclosure relates to a spatio-temporal stimulus responsive foldable structure. The structure may have a substrate having at least a region formed to provide engineered weakness to help facilitate bending or folding of the substrate about the region of engineered weakness. The substrate is formed to have a first shape. A stimulus responsive polymer (SRP) flexure is disposed at the region of engineered weakness. The SRP flexure is responsive to a predetermined stimulus actuation signal to bend or fold in response to exposure to the stimulus actuation signal, to cause the substrate to assume a second shape different from the first shape.

  • Patent number: 11262514
    Abstract: The present disclosure relates to a hybrid opto-electrical module apparatus. The apparatus may have a module substrate having a plurality of electrically conductive circuit traces for carrying electrical signals, and at least one waveguide element for carrying optical signals. A waveguide substrate is in optical communication with the waveguide element. A transducer is supported on the waveguide substrate and in electrical communication with the circuit traces. The waveguide substrate has at least one three dimensional (3D) waveguide formed within its interior volume for routing optical signals between the waveguide element and the transducer. A first optical wirebond interfaces the waveguide element to the 3D waveguide, and a second optical wirebond interfaces the 3D waveguide to the transducer.

  • Patent number: 11169341
    Abstract: The present disclosure relates to an electro-optical modulator system having a source laser which generates an input optical signal. The input optical signal is received by an electro-optical module. The electro-optical module is implantable into an anatomy and includes a plurality of pixels. Each pixel has associated therewith an electrode and an optical modulator subsystem. The electrode receives electrical signals from the anatomy. The optical modulator subsystem receives the input optical signal and modulates the input optical signal to generate modulated optical output signals in relation to the received electrical signals. A detector subsystem may be used to receive and collect the modulated optical output signals.

  • Patent number: 10695581
    Abstract: An optoelectrode having a lens optically coupled between a light source and a light guide and a method of making an optoelectrode. In one embodiment of the optoelectrode, the lens is a gradient index (GRIN) lens and the light source is a side-emitting injection laser diode (ILD).
