Coherent light emission from a nanosystem embedded within a polaritonic band-gap medium

The effect of an external quantum electric field on the surface plasmons of a nano-system

“…Hence, with the inclusion of the external electric field, we witnessed another reduction in the width of the spectrum of the emitted light, about ten folds below of Ref. [5], 10 11 s −1 when calculated at the same value of the pumping p . In other words, both of the effect of the external field and the PBG material has combined together to decrease the spectral width by an order of 10 5 times below which when these two factors were not included.…”

“…[5], I apply the above to silver nano particle embedded within silica carbide PBG material. The real and imaginary values of the dielectric constant have been modified to account for the size of the NP as done in Ref.…”

“…emitted from the system, as shown in Ref. [5], rendering the sensing operation much more sensitive and accurate. And with the external field being at or near resonance with the sensor, the accuracy of this photo-sensor is even more enhanced as shown throughout this paper.…”

“…In another paper, it was shown that the spectral width can be reduced greatly, about three orders of magnitude, by embedding the system of the NP and the TLS in a PBG material [5].…”
