Abstract

We describe an approach to optical non-reciprocity that exploits the local helicity of evanescent electric fields in axisymmetric resonators. By interfacing an optical cavity to helicity-sensitive transitions, such as Zeeman levels in a quantum dot, light transmission through a waveguide becomes direction-dependent when the state degeneracy is lifted. Using a linearized quantum master equation, we analyze the configurations that exhibit non-reciprocity, and we show that reasonable parameters from existing cavity QED experiments are sufficient to demonstrate a coherent non-reciprocal optical isolator operating at the level of a single photon.

(a) The proposed non-reciprocal device acting as an optical diode. (b) Forward (blue) and backward (red) transmission spectra for a nonzero QD excited state splitting. Coupling between the counter-propagating resonator modes and the helicity-sensitive Zeeman-split excited states of the QD results in directional asymmetry of the spectra. At a certain frequency (shown by the dashed line) the system exhibits a high degree of contrast Tf/Tb.

Fig. 2

Cross-sectional plots of normalized |E| and P for the M = 129 CW fundamental (ab) quasi-TE and (c–d) quasi-TM modes of a silicon nitride microring of outer radius 20 μm. Arrows indicate the direction of the E field in the ρ-z plane. The frequency of this particular mode is ωC/2π = 194.0 THz, although the general features are independent of M, geometry, and frequency. The region of the evanescent field directly (a–b) on top or (c–d) on the side of the cavity has a value of P near unity and a large value of |E|. Finite element calculations were performed with COMSOL Multiphysics [28].

Fig. 3
Fig. 3

(a) Schematic of our non-reciprocal optical device, consisting of a waveguide evanescently coupled to a WGM cavity interacting with a QD at (ρ′, ϕ′, z′). κex is the coupling from the waveguide into the cavity and vice-versa, κi is the decay rate of the cavity modes, and h is the backscattering in the cavity. Tf and Tb are the transmission for forward and backward propagating light in the waveguide respectfully. (b) Energy levels of the quantum dot. The two excitonic excited states couple to electric fields of opposite helicity.

Exciton-polariton energy eigenvalues λE of as a function of (a) the splitting δ12 in the ideal case, and (b) the helicity p. Dashed lines indicate the conditions for the spectra in Figs. 5(a)–5(b) and blue (red) indicates the forward (backward) sub-system. Other parameters are (g0, κi, κex) = (20, 3, 5)γ. The three eigenvalues for p = 0 are characteristic of standard cavity QED with axisymetric resonators [24, 25, 32].

Fig. 5
Fig. 5

Forward (blue) and backward (red) transmission spectra in (a) the ideal case with zero excited-state splitting, (b) the ideal case with non-zero splitting, and (c–d) the non-ideal case with non-zero splitting. Other parameters are (g0, κi, κex) = (20, 3, 5)γ, ϑ = π/4.

(a) The forward transmission with δ12 and ΔC set by Eqs. (18)(19). (b) The splitting δ12 set by Eq. (18) for several values of g0. The dashed line shows the optimal value of κex to maximize Tf for g0 = 20γ. Other parameters are (h, κi) = (0, 5)γ, p = 1, and ϑ = π/4.

Contour plots of (a) the isolation contrast Tf/Tb and (b) Tf for variable κex and δ12 in the non-ideal case of h = 20γ, p = 0.8 and ΔC set to the cavity-like dip in the Tb spectrum. The dashed line indicates where Tb = 0 may occur and the cross indicates the parameter location of optimal contrast. Other parameters are (g0, κi) = (20, 5)γ and ϑ = π/4.
