Abstract: The present disclosure relates to a multi-core optical fiber cable (MCF). In some embodiments, an MCF comprises a plurality of cores surrounded by a cladding and a coating surrounding the cladding, wherein a refractive index of one or more of the plurality of cores is greater than a refractive index of the cladding. The MCF further comprises a probe comprising a probe tip coupled with a distal end of the MCF and a lens located at a distal end of the probe tip. In some embodiments, the lens is configured to translate laser light from the distal end of the MCF to create a multi-spot pattern of laser beams on a target surface and a distal end of the MCF terminates at an interface with the lens.

Abstract: An example laser probe comprises one or more fibers extending from a proximal end of the laser probe to at least near a distal end of the laser probe, where the proximal end of the laser probe is configured to be coupled to a laser source via an adapter interface, and a cannula having a distal end and surrounding the one or more fibers along at least a portion of the laser probe at or near the distal end of the laser probe. The laser probe further comprises one or more lens elements, where each lens element is fused to or formed directly on the distal end of a corresponding one of the one or more fibers. In some embodiments, the laser probe is a multi-fiber, multi-spot laser probe, e.g., comprising four or more fibers and four or more corresponding lens elements.

Abstract: The present disclosure relates to a MCF (200A), including a plurality of cores (102), an outer cladding (101) or tube, diffusion barriers (202), and claddings (103). The diffusion barriers (202) and claddings (103) are designed so that unwanted migration of dopants from the inner cladding to the outer cladding or tube is reduced, or that unwanted migration of dopants from the cores to the outer cladding or tube is reduced. The doping levels of the various components of the MCF can be controlled in order to reduce dopant migration. The reduction in dopant gradients reduces the migration of dopants and bubbles to the interfaces between the inner claddings, the outer cladding or tube, and the cores.

Abstract: OF THE DISCLOSURE In certain embodiments, a system, a computer-implemented method, and computer- readable medium are disclosed for performing integrated analysis of MSI and OCT images to diagnose eye disorders. MSI and OCT are processed using separate input machine learning models to create input feature maps that are input to an intermediate machine learning model. The intermediate machine learning model processes the input feature maps and outputs a final feature map that is processed by one or more output machine learning models that output one or more estimated representations of a pathology of the eye of the patient. A single device captures OCT and non-OCT images using (a) a sensor of a first imaging device that is shared with a second imaging device and/or (b) an optical component for directing light form the retina to the first imaging device or the second imaging device.

Abstract: In certain embodiments, a system for sensing occlusions in an optical system includes a first laser source configured to generate optical signals and a set of optical elements arranged to receive the optical signals from the first laser source and to direct the optical signals along a beam path. The system also includes a detector arranged to receive reflections of the optical signals travelling along at least a portion of the beam path and a control system communicably coupled to the detector. The control system is configured to detect, based on signals generated by the detector, reflection signals associated with the reflections of the optical signals, and disable a second laser source based on detection of the reflection signals.
