“…To anticipate these problems, alternative proposals for the creation of optical diodes and isolators have been suggested in recent years. Some representative examples include the creation of optical diodes based on asymmetric nonlinear absorption [3], second harmonic generation in asymmetric waveguides [4], nonlinear photonic crystals [5], and photonic quasi-crystals and molecules [6].…”

“…The proposed devices can be broadband but their size is determined by the coherence length of the transitions, which, for reasonable modulation amplitudes, is several wavelengths, making these devices rather bulky. Nonlinearities have also been proposed to induce nonreciprocity [14][15][16][17][18] but the operation of the resulting devices is limited to specific ranges of input power. All these solutions rely on inherently weak effects, requiring large volumes, and are therefore not necessarily preferable to conventional solutions based on magneto-optical effects.…”

Giant non-reciprocity at the subwavelength scale using angular momentum-biased metamaterials

Breaking time-reversal symmetry enables the realization of non-reciprocal devices, such as isolators and circulators, of fundamental importance in microwave and photonic communication systems. This effect is almost exclusively achieved today through magneto-optical phenomena, which are incompatible with integrated technology because of the required large magnetic bias. However, this is not the only option to break reciprocity. The Onsager-Casimir principle states that any odd vector under time reversal, such as electric current and linear momentum, can also produce a non-reciprocal response. These recently analysed alternatives typically work over a limited portion of the electromagnetic spectrum and/or are often characterized by weak effects, requiring large volumes of operation. Here we show that these limitations may be overcome by angular momentum-biased metamaterials, in which a properly tailored spatiotemporal modulation is azimuthally applied to subwavelength Fano-resonant inclusions, producing largely enhanced non-reciprocal response at the subwavelength scale, in principle applicable from radio to optical frequencies.

“…the nonlinearity of the composite system is asymmetric, the rectification of one-dimensional photons transport can be controlled. The one way transport is called optical diode [9]. In this section, we will show that our compound system can worked as a photonic diode.…”

“…The rectifying device related with nonlinearity is the key device to information processing in integrated circuits [8]. Considerable efforts has been made to investigate the optical diodes [9]. Recently, various possible solid-state optical diodes have been proposed, for example the diodes from standard bulk Faraday rotators [10], integrated on a chip [11], realized in opto-acoustic fiber [12] and from moving photonic crystal [13].…”

Controlling photon transport in the single-photon weak-coupling regime of cavity optomechanics

We study the photon statistics properties of few-photon transport in an optomechanical system where an optomechanical cavity couples to two empty cavities. By analytically deriving the oneand two-photon currents in terms of a zero-time-delayed two-order correlation function, we show that a photon blockade can be achieved in both the single-photon strong-coupling regime and the single-photon weak-coupling regime due to the nonlinear interacting and multipath interference. Furthermore, our systems can be applied as a quantum optical diode, a single-photon source, and a quantum optical capacitor. It is shown that this the photon transport controlling devices based on photon antibunching does not require the stringent single-photon strong-coupling condition. Our results provide a promising platform for the coherent manipulation of optomechanics, which has potential applications for quantum information processing and quantum circuit realization.
