Slideshow

Slideshow demonstrates how P-SOT works.

  • PSOT makes use of wavelength division multiplexers and demultiplexers to combine and split beams of light. (E.g. A red and blue beam is multiplexed into a magenta beam which carries both states simultaneously.)
  • PSOT components and optical transistors have multiple substrates, each handling a specific colour. The colour at the gate (grey terminal) if matching the substrates defines which of the input beams (left of component) will go through. (E.g. Red was isolated from a magenta beam by applying red to the gate.)
  • PSOT components will not let through under any condition light beams that aren't the same colour as the component's substrates.
  • Multiplexers can help to select multiple specific colour beams on one PSOT component. Red and blue, or a magenta beam, was picked out of an RGB white beam input.
  • Single direction mirrors can allow beams to travel bidirectionally
  • PSOT components only make the substrate transparent, hence their input and output terminals are bidirectional.
  • This still works for multiple beam colours simultaneously.
