i have read through a mathematical description of the quantization of the electric field through the simple harmonic oscillator raising/lowering operators. what is the physical interpretation and justification for this?(adsbygoogle = window.adsbygoogle || []).push({});

what if one assumes that photons do not behave like simple harmonic oscillators... but (perhaps) say bound states in an infinite square well. how would this change field quantization?
