- Abstract: We derive a master equation for a superradiant medium which includes
multilevel interference betwen the individual scatterers. The derivation relies
on the Born-Markov approximation and implements the coarse graining formalism.
The master equation fulfils the Lindblad form and contains terms describing
single-atom multilevel interference, multi-atom interference between identical
transitions, and multi-atom interference between different electronic
transitions with parallel dipoles. This formalism is then applied to determine
the excitation spectrum of two emitters using the parameters of the Hydrogen
transitions 2S$_{1/2}\,\to$4P$_{1/2}$ and 2S$_{1/2}\,\to$4P$_{3/2}$, where the
gap between the parallel dipoles is of the order of GHz. The distortion of the
signal due to the interplay of multilevel and multi-emitter interference is
analysed as a function of their distance. These results suggest that
interference between parallel dipolar transition can significantly affect the
spectroscopic properties of optically dense media.

We develop and investigate an integrated multimode two-colour SU (1,1) interferometer that operates in a supersensitive mode.
By ensuring a proper design of the integrated platform, we suppress dispersion and thereby significantly increase the visibility of the interference pattern.
We demonstrate that such an interferometer overcomes the classical phase sensitivity limit for wide parametric gain ranges, when up to $3*104$ photons are generated.
