Abstract: Embodiments for environmental control of a vehicle by a processor. An environmental change in the vehicle is predictively anticipated by monitoring at least one environmental factor over time. In response to the predicted environmental change, a physical change is caused in a constituent portion of an assembly inclusive of an external surface of the vehicle, which when activated compensates for the predicted environmental change.

Abstract: Disclosed herein are apparatus, devices, and methods to provide a modified-transmissivity zone on a projection surface used to generate a virtual image superimposed onto a real-world view. In particular, a variable-transmissivity material may be provided in the projection surface. The transmissivity of variable-transmissivity material may be modified responsive to application of a stimulus. A stimulus source may be configured to selectively apply a stimulus to the variable-transmissivity material to generate a discrete modified-transmissivity zone on the projection surface.

Abstract: Embodiments of the present disclosure provide devices and methods involving the thermal stabilization of microring resonators, such as microring modulators. Power is measured via an on-chip photodetector integrated with a drop port of the microring resonator, providing a local measurement of average power. This average power is employed as a feedback measure to actively control a heater that is integrated with the microring resonator, in order to stabilize the resonant wavelength of the microring resonator in the presence of thermal fluctuations. Employing such a system, a microring modulator can maintain error-free performance under thermal fluctuations that would normally render it inoperable.

Abstract: A reflective structure includes an input/output port and an optical splitter coupled to the input/output port. The optical splitter has a first branch and a second branch. The reflective structure also includes a first resonant cavity optically coupled to the first branch of the optical splitter. The first resonant cavity comprises a first set of reflectors and a first waveguide region disposed between the first set of reflectors. The reflective structure further includes a second resonant cavity optically coupled to the second branch of the optical splitter. The second resonant cavity comprises a second set of reflectors and a second waveguide region disposed between the second set of reflectors.

Abstract: A fast optical switch can be fabricated/constructed, when vanadium dioxide (VO2) ultra thin-film or a cluster of vanadium dioxide particles (less than 0.5 microns in diameter) embedded in an ultra thin-film of a polymeric material or in a mesh of metal nanowires is activated by either an electrical pulse (a voltage pulse or a current pulse) or a light pulse just to induce rapid insulator-to-metal phase transition (IMT) in vanadium dioxide ultra thin-film or vanadium dioxide particles embedded in an ultra thin-film of a polymeric material or in a mesh of metal nanowires. The applications of such a fast optical switch for an on-Demand optical add-drop subsystem, integrating with or without a wavelength converter are also described.
