“…The result of numerical simulation shows excellent agreement with the exact soliton solution in Eq. (41). However, when the decay rate for the biexciton coherence increases, the bright soliton intensity reduces in a short propagation distance, as shown in Fig.…”

“…Many approaches for realizing EIT * wenxingyang2@126.com in semiconductor devices have been proposed theoretically and reported experimentally [23][24][25][26][27][28][29]. One of the important motivations comes from mature semiconductor manufacturing technologies [30][31][32][33][34][35][36][37][38][39][40][41][42][43][44], for which the interaction between semiconductor devices and optical light fields is strongly enhanced in comparison with atomic systems due to the achievable large dipole moments [45]. Nonlinear optical experiments can be performed with pulses of a few hundreds of femtoseconds, which are long compared to the inhomogeneous broadening but short enough so that the electron-phonon interaction, which acts on a picosecond time scale, can be neglected [46][47][48], offering time scales necessary for coherent interaction.…”

Matched slow optical soliton pairs via biexciton coherence in quantum dots

We theoretically investigate the simultaneous formation and stable propagation of slow optical soliton pairs in semiconductor quantum dots with a four-level biexciton-exciton cascade configuration. Owing to the destructive interference set up by two continuous wave control fields that couple to a biexciton state, the linear as well as nonlinear dispersion can be dramatically enhanced simultaneously with the absorptions of two weak probe fields being almost suppressed. These results reveal that the detrimental distortions of the two weak-pulsed probe fields due to dispersion effects can be well balanced by the self-phase modulation effect under very low input light intensity, which leads to the slow temporal optical soliton pairs with matched group velocity and amplitude. We also show that the propagation of slow optical solitons can be strongly modified by the biexciton coherence.

Semiconductor photonics is an advanced field, both from fundamental and applicative points of view, aimed at the integration of the unique features of optical communications and quantum optics with the miniaturization and controllability of semiconductors. Many classical and quantum applications may benefit from interaction between optical signals, usually implemented by nonlinear optical processes of various orders. The efficiency of such processes in semiconductors is being constantly enhanced, assisted by the progress in ultrashort laser pulses and ultra-sensitive detectors, enabling practical devices. In this review, the lowest order of nonlinear interactions-the two-photon processes in semiconductors-are discussed, and their applications to a variety of novel classical and quantum configurations are reviewed.

“…Two-photon emission (TPE) refers to the simultaneous emission of two photons during a quantum radiative transition [1][2][3][4][5][6][7][8][9][10][11][12][13][14]. Recent researches suggest TPE as a promising approach to generate entangled photon pairs in semiconductors, as it emits two photons with intrinsic energy conservation and time coincidence [15].…”

As a high-order quantum transition, two-photon emission has an extremely low occurrence rate compared to one-photon emission, thus having been considered a "forbidden" process. Here, we propose a scheme that allows ultrafast two-photon emission, leveraging highly confined surface plasmon polariton modes in a degenerately-doped, light-emitting semiconductor thin film. The surface plasmon polariton modes are tailored to have simultaneous spectral and spatial overlap with the two-photon emission in the semiconductor. Using degenerately-doped InSb as the prototype material, we show that the two-photon emission can be accelerated by 10 orders of magnitude: from tens of milliseconds to picoseconds, surpassing the one-photon emission rate. Our result provides a semiconductor platform for ultrafast single and entangled photon generation, with a tunable emission wavelength in the mid-infrared.
