1. A system for generating spectrally compressed photons from broadband emitted photon pulses, comprising:
a coupling device comprising an input coupling having a first coupling ratio, wherein the first coupling ratio is configurable, and an output coupling having a second coupling ratio, wherein the second coupling ratio is fixed;
a cavity connected to the input coupling and the output coupling; and
a controller in electrical communication with the coupling device, the controller configured to change the first coupling ratio of the input coupling, wherein the spectrally compressed photons are generated from the coupling device through the output coupling.
