Light-based ComputingJanuary 1, 2020
Light, as analog waves, carry more data as “R-O-Y-G-B-I-V” than electrons that can only carry digital binary data as “ON-OFF” at a time. This analog light data can then be absorbed by glass or semiconductor crystals to be processed by normal computer logic.
This principle was recently proven to be realizable in Germany . In their experiment, intense light pulses of waves ranging from near-infrared to visible orange were used to generate oscillating currents in a chip made with gallium arsenide. The chip then emitted terahertz radiation from the oscillations.
This tapping onto the dynamic wave-nature of light is a marked advancement over the use of lasers which are of a fixed or single wavelength. Examples of the latter technologies are:
Examples or precusors of dynamic wavelength technologies are:
- the use of short bursts of light to store more data
- the use of light-based in-memory processors by IBM using different optical wavelengths for each calculation
