摘要： Light recycling within a waveguide is achieved by mode conversion instead of resonance. A structure is provided in in which light makes multiple passes through the same waveguide by converting the mode to a different mode after each pass and rerouting the light back into the same waveguide. The structure includes a bus waveguide and at least one mode converter device disposed at or adjacent each of two opposing ends of the bus waveguide, wherein each mode converter devices is configured to receive light having a receiving mode along a first direction and to cause light having a different mode from the receiving mode to propagate in a second direction opposite the first direction.

摘要： Provided are devices that have a distal portion configured to be implanted in a brain of a subject. The distal portion includes one or more emitters configured to emit light in the visible spectrum. The device includes a proximal portion configured to be external to the brain of the subject while the distal portion is implanted, wherein the proximal portion includes at least one waveguide in optical communication with the one or more emitters. The at least one waveguide defines a cross-sectional width less than 500 nm. The at least one waveguide is optionally coupled to a heating element that is optionally configured to adjust a phase of light within the at least one waveguide.
