Fractal Light: Lowest Loss Eigenmodes

Codes were written to simulate the propagation of monochromatic light through a bare optical resonator, using a computational Fourier method to solve the Huygens-Fresnel integral. This was used, in the Fox-Li method, to find the lowest-loss eigenmodes of arbitrary cavity designs. An implicit shift `hopping' method was employed to allow a series of increasingly higher-loss eigenmodes to be found, limited in number by computational time. `hopping' method was employed to allow a series of increasingly higher-loss eigenmodes to be found, limited in number by
computational time. `hopping' method was employed to allow a series of increasingly higher-loss eigenmodes to be found, limited in number by

This is a vide of the eigenmode location; each frame is a roundtrip of light around the cavity. The 'G' factor on the bottom is the eigenvalue for the last transform (this will stabilise as an eigenmode is found). Once the first eigenmode is found, this is used with the implicit shift method (when a character is displayed in the top left) to find higher order (greater loss) modes.

Sorry there PuppyGuts - lifted the description pretty much word-from-word from the abstract of my MSci report - pretty dense scientific lingo!

Basically - t'is pretty, admire it.

What more is there to life than pretty pictures?

I'm so fucking high right now.

[Differentiated]

Me and Joseph Fourier were buddies

[thehaircrow]

lmao

[bobfrost123]

Wow. Best thing I've seen on YouTube.

[RotogenRay]

just start with cavity resonators and work your way up the spectrum

[zerhatti]

:)) me and Gauss were brothers

i love simulating the propagation of monochromatic light through a bare optical resonator, using a computational Fourier method to solve the Huygens-Fresnel integral! ha ha i don't have a clue, are we speaking english?
