Abstract: An optical numerical computation method obtains operands that have respective values and modulates light sources to output light at amplitudes proportional to the operands. The light output for a given operand depends on whether the operand is positive or negative. The positive operands are output at wavelengths different from the negative operands. For operands that have multiple digits, the digits are separately treated so that the least significant digits are modulated with light sources at one frequency, and the most significant digits in two-digit numbers are modulated at another frequency, with positive and negative operands modulated at different frequencies. The light from the light sources enters a light collection cavity where it is sensed with sensors that generate resultant outputs at values indicative of the sensed light value.

Abstract: A light source is realized in a wall portion and a base portion forming a flexible structure, the wall portion having a plurality of inward facing LEDs, a bottom edge of the wall portion being adjacent to an edge of the wide portion. The resulting well is subsequently filled with a material to form an optical cavity, the height of the resultant optical cavity being matching a top edge of the wall portion. The top surface of the optical cavity is spin coated with a thin layer of quantum dots which serve to shift a wavelength of light emitted from the LEDs. Finally, a protective layer is applied to fix and protect the thin layer of quantum dots. Thus, a light source is realized which can reliably provide light at a specific wavelength defined by the interaction between the LEDs and quantum dots.

Abstract: A computing apparatus has a logic unit configured to perform an arithmetic operation by relating light beams, each having a respective light amplitude, to obtain a light-based result of the operation, and to evaluate the light-based result to output a corresponding numeric result. The logic unit uses variables values, each corresponding to a respective distinct light amplitude, the variable values thereby corresponding to a plurality of distinct light amplitudes.

Abstract: An optical numerical computation device relates light from a plurality of light sources to calculate an arithmetic solution. The optical numerical computation device includes input circuitry, pre-calculation circuitry, calculation circuitry, a light collection cavity, and a plurality of light computation components. The pre-calculation circuitry and calculation circuitry cause light sources to emit light representing the values of input operands, which is subsequently related within the light collection cavity. Sensors then generate resultant outputs at values indicative of the sensed light value. The respective wavelength of light emitted from or sensed by each light computation component may be associated with an operand arithmetic sign.
