"Researchers get spiking neural behavior out of a pair of transistors" (2025) https://news.ycombinator.com/item?id=43506198
What are the ways to get spiking behavior out of integrated nanophotonics?
Saturable Absorption (excitable semiconductor lasers, graphene laser cavity,), NDR Negative Differential Resistance (RTD Resonant Tunneling Diodes,), PCM: Phase-change materials (DVD-RW,),
Metamaterials and metasurfaces are probably useful for extreme nonlinear spiking neuromorphic computing with integrated nanophotonics.
What about Optical rogue waves, Supercontinuum generation (color, wave division multiplexing, ); and/or Superradiance (as nonlinear optical effects for a neuromorphic computation platform)? ... https://news.ycombinator.com/item?id=41684444

Superradiance: https://en.wikipedia.org/wiki/Superradiance :
> Superradiance has since been demonstrated in a wide variety of physical and chemical systems, such as quantum dot arrays [4] and J-aggregates. [5] This effect has been used to produce a superradiant laser.
