  • Patent number: 10951007
    Abstract: An optically pumped tunable VCSEL swept source module has a VCSEL and a pump, which produces light to pump the VSCEL, wherein the pump is geometrically isolated from the VCSEL. In different embodiments, the pump is geometrically isolated by defocusing light from the pump in front of the VCSEL, behind the VCSEL, and/or by coupling the light from the pump at an angle with respect to the VCSEL. In the last case, angle is usually less than 88 degrees. There are further strategies for attacking pump noise problems. Pump feedback can be reduced through (1) Faraday isolation and (2) geometric isolation. Single frequency pump lasers (Distributed feedback lasers (DFB), distributed Bragg reflector lasers (DBR), Fabry-Perot (FP) lasers, discrete mode lasers, volume Bragg grating (VBG) stabilized lasers can eliminate wavelength jitter and amplitude noise that accompanies mode hopping.

  • Publication number: 20210075190
    Abstract: A microelectromechanical systems (MEMS)-tunable vertical-cavity surface-emitting laser (VCSEL) in which the MEMS mirror is bonded to the active region. This allows for a separate electrostatic cavity that is outside the laser's optical resonant cavity. Moreover, the use of this cavity configuration allows the MEMS mirror to be tuned by pulling the mirror away from the active region. This reduces the risk of snap down. Moreover, since the MEMS mirror is now bonded to the active region, much wider latitude is available in the technologies that are used to fabricate the MEMS mirror. This is preferably deployed as a swept source in an optical coherence tomography (OCT) system.

  • Publication number: 20210050712
    Abstract: A vertical cavity surface emitting laser (VCSEL) has a shortened overall laser cavity by combining the gain section with a distributed Bragg reflector (DBR). The overall cavity length can be contracted by placing gain structures inside the DBR. This generally applies to a number of semiconductor material systems and wavelength bands, but this scheme is very well suited to the AlGaAs/GaAs material system with strained InGaAs quantum wells as a gain medium, for example.

  • Patent number: 10920942
    Abstract: A rear facing light bar assembly that incorporates a plurality of light functions in a small integrated unit. A multifunctional circuit board powers different colored light emitting diodes to produce the tail light, brake light, amber and/or backup light. The assembly also has end caps, a one-piece polycarbonate tube lens and an extruded housing. Heat from the circuit board is dissipated through the end caps and into the extruded housing. The assembly is constructed such that the electronics are completely protected from the outside environment, and sealed from water and dust intrusion. The light also minimizes tooling and assembly cost, yet provides a secure seal protecting the electrical components. In addition, the light is serviceable so individual parts can be replaced or repaired if parts are damaged.

  • Publication number: 20210039317
    Abstract: A consumable assembly for supplying filament to a 3D printer includes a spool-less filament coil, a payout tube, and a compressive band. The coil of filament is wound in a configuration having a generally cylindrical outer perimeter and an open interior; the coil has a payout hole extending from an inner layer of the coil to an outer layer of the coil and includes a filament strand configured to be withdrawn through the payout hole in response to a pull force, to thereby withdraw filament from the interior of the coil. The payout tube is disposed in the payout hole and provides a filament port. A compressive band is disposed over the outer layer and is configured to exert a compressive radial force on the coil so that the coil maintains its cylindrical shape without deformation, and the filament strand may be drawn through the filament outlet free of kinks, twists or tangles.

  • Publication number: 20210005927
    Abstract: Systems and methods are provided for a slurry for coating an electrode structure. In one example, a method may include dispersing, by mixing at one or both of a high shear and a low shear, a solid ionically conductive polymer material in at least a first portion of a solvent to form a suspension, then dispersing, by mixing at the one or both of the high shear and the low shear, one or more additives in the suspension, and then mixing, at the one or both of the high shear and the low shear, a second portion of the solvent with the suspension to form a slurry. As such, the slurry including the solid ionically conductive polymer material may be applied as a coating in a solid-state battery cell, which may reduce resistance to Li-ion transport and improve mechanical stability relative to a conventional solid-state battery cell.
