Resonance fluorescence and phase-dependent spectra of a singly charged n -doped quantum dot in the Voigt geometry

Absorption of a weak probe in singly charged n-doped quantum dots in the Voigt geometry

“…The narrowness of the absorption and gain peaks is reminiscent of the subnatural Raman photons appearing in the resonance fluorescence spectrum experimentally studied in [17]. Those photons still exhibit a subnatural linewidth for a wide range of values of the Rabi frequency of the pump field [30].…”

“…Much of the research into these systems has focused either on better understanding the confined energy states of electron and holes within them, and also on how to exploit their quantum nature for practical applications. Those applications range from the coherent manipulation of exciton wave functions [7], optical pumping [8][9][10][11][12], resonance fluorescence [13][14][15][16][17][18][19][20][21][22][23][24][25][26][27][28][29][30][31], single photon generation [26,32], rotations of the spin vector [33][34][35][36][37], quadrature squeezing and antibunching [38], coherent population trapping [39][40][41][42][43][44], all-optical switching [45], to the entanglement of distant QDs [46], and they have helped to unlock their potential.…”
