35)] is satisfied], the system will spase. The same is true for nonpropagating modes whose frequencies are in the band gap. In fact, at the band edge or in the band gap, a metamaterial with gain is similar to a DFB laser [96]—see also the next paragraph. There has been a recent experimental observation [33] of an electrically pumped DFB nanolaser (spaser) working in the communication frequency range at room temperature. This spaser generates on a stop-band (nonpropagating) plasmonic mode, that is, a mode with frequency within the band gap.

S = (γn + γs ) We will also examine the spaser as a bistable (logical) amplifier. One of the ways to set the spaser in such a mode is to add a saturable absorber. 19) one has to set g = 0. Numerical examples are given for a silver nanoshell where the core and the external dielectric have the same permittivity of εd = 2; the permittivity of silver is adopted from Reference 69. 4 × 1020 cm−3 , which is realistic for dye molecules but may be somewhat high for semiconductor QDs that were proposed as the chromophores [15] and used in experiments [46].

As we see from panel (c), independent of the initial number of SPs, the spaser always generates a series of SP pulses, of which only the first pulse is large (at or above the logical level of Nn ∼ 100). ) The underlying mechanism of such a response is the rapid depletion of the inversion seen in panel (d), where energy is dissipated in the metal of the spaser. The characteristic duration of the SP pulse ∼ 100 fs is defined by this depletion, controlled by the energy transfer and SP relaxation rates.
