Here, by exploiting the platform of atomic-cladding wave guides, the resonant coupling of rubidium vapor and an atomic cladding micro ring resonator is experimentally demonstrated. Specifically, cavity-atom coupling in the form of Fano resonances having a distinct dependency on the relative frequency ...
It is well-known that the presence of buffer gas (such as Helium or Ethane) in atomic vapor causes rapid spin-relaxation between the J=3/2 and J=1/2 states and increased absorption cross-section. In this work, we employ cascade transitions in Rubidium to take advantage of this to ...

The all-optical switch consists of a pair of light beams that counter propagate through warm rubidium vapor. These beams induce a nonlinear optical instability that gives rise to mirrorless parametric self-oscillation and generates light in the state of polarization that is orthogonal to that of ...
We have observed optical bistability in rubidium vapor enclosed in a Fabry-Perot cavity for λ 7779 (two-photon transition) and λ 7800 (one-photon transition). We have measured the switching time τ S as a function of ( l l c) where l c is the last value of the length of the ...
A fiber optic-based all-optical amplifier is designed by using the coherent perfect absorption phenomenon. For this purpose, we use a deposited chromium thin layer as an absorbent material on the cross-section of a PM fiber. By placing another fiber in front of the deposited one, we show th...
