“…In order to study the basic physics of these processes, there has been an intensive search for laser operation in fundamental systems [2]. The resulting drive toward miniaturization has led to, among others, the realization of vertical-cavity semiconductor lasers [3], dye microsphere lasers [4], microring and microdisk semiconductor lasers [5], and photonic bandgap lasers [6]. As laser systems are made smaller, a purely macroscopic description becomes inadequate and microscopic considerations should be taken into account.…”

Using a density matrix approach, we study the simplest systems that display both gain and feedback: clusters of 2 to 5 atoms, one of which is pumped. The other atoms supply feedback through multiple scattering of light. We show that, if the atoms are in each other's near field, the system exhibits large gain narrowing and spectral mode redistribution. The observed phenomena are more pronounced if the feedback is enhanced. Our system is to our knowledge the simplest exactly solvable microscopic system which shows the approach to laser oscillation.

“…For examples, they can be used as near-zero threshold lasers, novel waveguides, optical switches, chemicals, and biochemical sensors [3][4][5][6][7][8][9][10]. Current approaches are used to produce PC assemblies within a spectral region between ultraviolet and microwave frequencies.…”
