Enhancement of four-wave mixing process in a four-level double semiconductor quantum well

“…[1][2][3] The optical field propagation in the optical medium under EIT configuration displays several striking features, including a large suppression of optical absorption, a significant reduction of group velocity, and a giant enhancement of Kerr nonlinearity, etc. [4][5][6][7][8][9][10][11][12] Based on these interesting features, four-wave mixing (FWM), as one of the striking nonlinear quantum optical phenomena, has been explored recently in the EIT media because of its potential applications in frequency conversion, quantum entanglement, and stopped light. [13][14][15][16][17][18] The first experimental demonstration of EIT-based FWM was reported by Zhang et al, and then a significant enhancement of the FWM process by using EIT was observed in rubidium atomic vapor.…”
