Stanford researchers have developed a simple optical device for low-power, active light tuning. The device tunes the color of light across the visible spectrum and at select wavelengths by electrical biasing an array of micron sized pixels or nanowires.
Machine learning models currently require extensive computational resources and this demand is growing rapidly with new models and applications being introduced.
