Abstract: A higher order mode generator is for converting the 0 th order fundamental guiding mode into higher modes higher than the 0 th order in a waveguide. The waveguide is made from thermo-optic materials in which the refractive index is changed according to the applied electrical power. The waveguide has at least two guiding modes and a straight heater or a linear electrode to invoke refractive index perturbation due to temperature or electric field, and is laid across the waveguide at a certain tilt angle α with respect to the waveguide. When there is no external electric power applied to the heater/electrode, the 0 th order single mode light of the waveguide will be propagated through the waveguide without any conversion into higher order modes. When electric power is applied, the refractive index of the waveguide beneath the heater changes and higher order modes can be excited by external control.

Abstract: Recent remarkable progress in wave-front shaping has enabled control of light propagation inside linear media to focus and image through scattering objects. In particular, light propagation in multimode fibers comprises complex intermodal interactions and rich spatiotemporal dynamics. Control of physical phenomena in multimode fibers and its applications is in its infancy, opening opportunities to take advantage of complex mode interactions. Various embodiments of the present technology provide wave-front shaping for controlling nonlinear phenomena in multimode fibers. Using a spatial light modulator at the fiber's input and a genetic algorithm optimization, some embodiments control a highly nonlinear stimulated Raman scattering cascade and its interplay with four wave mixing via a flexible implicit control on the superposition of modes that are coupled into the fiber.

Abstract: Embodiments of the present disclosure relate to a high performance backlight device with photonic integrated circuits. The backlight device includes a light source assembly, a multi-mode slab waveguide, and an out-coupling assembly. The light source assembly includes one or more light sources that generate light in accordance with emission instructions, and a de-speckling mechanism that conditions the generated light to mitigate speckle. The multi-mode slab waveguide in-couples the conditioned light and expands the in-coupled conditioned light in two dimensions to form a homogenous area of conditioned light within a region of the multi-mode slab waveguide. The out-coupling assembly out-couples the conditioned light from the region in a direction normal to the two dimensions, wherein a light modulation layer forms an image from the out-coupled conditioned light.
