Waiting 4 months for a superficial and unsubstantiated peer-review rejection (reviewer #2, ofc. ) should not be normal. Reviewer #1 really liked the paper.

We hope this can be useful whenever resonances play a role. Kudos to whole team: Thomas Possmayer, @AndreasTittl, Leo Menezes and Stefan Maier!.

So we don't necessarily need to pattern samples through etching/deposition steps to have tailored resonances. Nothing more than a thin film gives us very interesting optical functionalities!

We can also use these resonances to enhance nonlinear responses at desired wavelengths in an ultrafast timespan, as we have done in the near IR

By changing the pump power, the amplitude and Q-factor of resonances can also be controlled, as we further break the permittivity symmetry with higher pulse energies, moving away from the BIC symmetric state

We can tune the resonances at will, for instance, by changing the wavelength or interfering angle between the beams. In principle, we could selectively modulate light propagation across the entire optical telecom range (from O to L bands) with a single silicon thin film

Even though we are using excited carriers, these resonances come and go quite fast (~ 1ps), because these carriers diffuse from bright to dark fringes, restoring the symmetry. But any other permittivity-changing mechanism could be used for symmetry breaking

When you interfere two beams at an angle in a film, bright and dark fringes are formed. Carriers are excited mainly in the bright fringes, breaking the continuous permittivity symmetry of the film. This permittivity symmetry breaking allows us to excite all-optical resonances

What note would an infinite string sound? What "color" would an infinite mirror cavity have? Any you want, but how to select it? In our preprint we show how to excite tailored resonances in a plain thin film using light to break its permittivity symmetry🔦.
