“…In 2004, Yanik et al proposed to dynamically modulate the refractive index to generate arbitrarily small group velocity for any light pulse with a given bandwidth. Using coupled cavity arrays [51] or waveguide-coupled cavity system [32], they showed that light pulses can be finally stopped and stored coherently with an all-optical adiabatic and reversible pulse bandwidth compression process ( Figure 17A and B). In 2007, Xu et al [38] reported the demonstration of light storage using fast electro-optical tuning of the resonator refractive index, with storage times longer than the bandwidth-determined photon lifetime of the static device.…”

Electromagnetically induced transparency in optical microcavities

Electromagnetically induced transparency (EIT)is a quantum interference effect arising from different transition pathways of optical fields. Within the transparency window, both absorption and dispersion properties strongly change, which results in extensive applications such as slow light and optical storage. Due to the ultrahigh quality factors, massive production on a chip and convenient all-optical control, optical microcavities provide an ideal platform for realizing EIT. Here we review the principle and recent development of EIT in optical microcavities. We focus on the following three situations. First, for a coupled-cavity system, all-optical EIT appears when the optical modes in different cavities couple to each other. Second, in a single microcavity, all-optical EIT is created when interference happens between two optical modes. Moreover, the mechanical oscillation of the microcavity leads to optomechanically induced transparency. Then the applications of EIT effect in microcavity systems are discussed, including light delay and storage, sensing, and field enhancement. A summary is then given in the final part of the paper.

“…This limitation was soon resolved by mimicking the EIT effect in classical oscillator systems [7] that have more merits than in the atomic systems. Recently, various resonant dielectric optical systems including coupled silicon-ring resonators system, photonic crystals, drop-filter cavity-waveguide systems, and a hybridized plasmonic-waveguide system have been proposed and demonstrated to display EIT-like spectral response at room temperature [8][9][10][11][12][13][14][15][16]. These realizations have further catalyzed an ongoing search for classical systems mimicking EIT.…”

Abstract:We present theoretical and numerical analysis of a plasmonic-dielectric hybrid system for symmetric and asymmetric coupling between silver cut-wire pairs and silicon grating waveguide with periodic grooves. The results show that both couplings can induce electromagnetically-induced transparency (EIT) analogous to the quantum optical phenomenon. The transmission spectrum shows a single transparency window for the symmetric coupling. The strong normal phase dispersion in the vicinity of this transparent window results in the slow light effect. However, the transmission spectrum appears an additional transparency window for asymmetry coupling due to the double EIT effect, which stems from an asymmetrically coupled resonance (ACR) between the dark and bright modes. More importantly, the excitation of ACR is further associated with remarkable improvement of the group index from less than 40 to more than 2500 corresponding to a high transparent efficiency by comparing with the symmetry coupling. This scheme provides an alternative way to develop the building blocks of systems for plasmonic sensing, all optical switching and slow light applications. ©2010 Optical Society of America IntroductionElectromagnetically-induced transparency (EIT) [1] is a quantum optical phenomenon to make an absorptive medium transparent to a resonant probe field owing to the destructive quantum interference between two pathways induced by a coupling field. The importance of EIT stems from the fact it gives rise to greatly enhanced nonlinear susceptibility in the spectral region of induced transparency and is associated with steep dispersion, allowing for many potential applications, such as the transfer of quantum correlations [2], nonlinear optical processes [3], and ultraslow light propagation [4][5][6]. However, the special experimental conditions for observing this EIT effect in atomic medium hinder its further practical application. This limitation was soon resolved by mimicking the EIT effect in classical oscillator systems [7] that have more merits than in the atomic systems. Recently, various resonant dielectric optical systems including coupled silicon-ring resonators system, photonic crystals, drop-filter cavity-waveguide systems, and a hybridized plasmonic-waveguide system have been proposed and demonstrated to display EIT-like spectral response at room temperature [8][9][10][11][12][13][14][15][16]. These realizations have further catalyzed an ongoing search for classical systems mimicking EIT. In particular, the plasmonic analogues of EIT in metamaterials, such as dipole antennas [17][18][19][20][21][22][23], fish scales metallic patterns [24], split-ring resonators [24][25][26][27][28][29][30][31], trapped-mode patterns [32,33], and array of metallic nanoparticles [34] which are the most recent and promising additions to the existing array of classical EIT schemes, have been demonstrated theoretically and experimentally. More recently, a method of phase-coupled plasmon-induced transparency has also been presented fo...

“…Moreover, our solid-state implementation has an achievable bandwidth of 50 ∼ MHz in contrast to less than 100 kHz in atomic systems, although the delay-bandwidth product is comparable. To obtain longer photon storage, one can consider dynamical tuning (Yanik et al, 2004;Xu et al, 2007;Yanik & Fan, 2007) to tune the cavity resonances with respect to the QD dipolar transitions to break the delay-bandwidth product in a solid-state cavity-QD array system.…”

We show that a scalable photonic crystal nanocavity array, in which single embedded quantum dots are coherently interacting, can perform as a universal single-operation quantum gate. In a passive system, the optical analogue of electromagnetically-induced-transparency is observed. The presence of a single two-level system in the array dramatically controls the spectral lineshapes. When each cavity couples with a two-level system, our scheme achieves two-qubit gate operations with high fidelity and low photon loss, even in the bad cavity limit and with non-ideal detunings.
