Abstract

We theoretically demonstrate high fidelity frequency conversion of a photon generated by a dipole-like emitter in a double mode nonlinear cavity irradiated by a classical field, and propose a realistic photonic crystal nanocavity implementation.

Resonant photon pair generation in coupled silicon photonic crystal nanocavities

Nobuyuki Matsuda, Eiichi Kuramochi, Hiroki Takesue +2 more

Generating correlated photons is an essential technology for photonic quantum information experiments. Increasing the generation efficiency of photon pairs via the enhancement of material nonlinearity is important for various applications including a near-on-demand single photon source based on multiplexed photon pair sources [1]. In this regard, photonic crystal nanocavities are attractive nonlinear media thanks to a high Q value and a wavelength-sized mode volume, which lead to the significant nonlinearity enhancement. However, such cavities generally support single resonant mode, whereas multiple resonance frequencies are required for photon pair generation processes. Coupled photonic crystal nanocavities have been studied to obtain multiple resonance frequencies [2-4]. However, there has been no report on the resonant photon pair generation from the coupled photonic crystal cavities.

Broadband frequency conversion and shaping of single photons emitted from a nonlinear cavity

Murray W. McCutcheon, Darrick E. Chang, Yinan Zhang +2 more

Much recent effort has focused on coupling individual quantum emitters to optical microcavities in order to produce single photons on demand, enable single-photon optical switching, and implement functional nodes of a quantum network. Techniques to control the bandwidth and frequency of the outgoing single photons are of practical importance, allowing direct emission into telecommunications wavelengths and "hybrid" quantum networks incorporating different emitters. Here, we describe an integrated approach involving a quantum emitter coupled to a nonlinear optical resonator, in which the emission wavelength and pulse shape are controlled using the intra-cavity nonlinearity. Our scheme is general in nature, and demonstrates how the photonic environment of a quantum emitter can be tailored to determine the emission properties. As specific examples, we discuss a high Q-factor, TE-TM double-mode photonic crystal cavity design that allows for direct generation of single photons at telecom wavelengths (1425 nm) starting from an InAs/GaAs quantum dot with a 950 nm transition wavelength, and a scheme for direct optical coupling between such a quantum dot and a diamond nitrogen-vacancy center at 637 nm.

Broad-band spectral control of single photon sources using a nonlinear photonic crystal cavity

Murray W. McCutcheon, Darrick E. Chang, Yinan Zhang +2 more

Motivated by developments in quantum information science, much recent effort has been directed toward coupling individual quantum emitters to optical microcavities. Such systems can be used to produce single photons on demand, enable nonlinear optical switching at a single photon level, and implement functional nodes of a quantum network, where the emitters serve as processing nodes and photons are used for long-distance quantum communication. For many of these practical applications, it is important to develop techniques that allow one to generate outgoing single photons of desired frequency and bandwidth, enabling hybrid networks connecting different types of emitters and long-distance transmission over telecommunications wavelengths. Here, we propose a novel approach that makes use of a nonlinear optical resonator, in which the single photon originating from the atom-like emitter is directly converted into a photon with desired frequency and bandwidth using the intracavity nonlinearity. As specific examples, we discuss a high-finesse, TE-TM double-mode photonic crystal cavity design that allows for direct generation of single photons at telecom wavelengths starting from an InAs/GaAs quantum dot with a 950 nm transition wavelength, and a scheme for direct optical coupling of such a quantum dot with a diamond nitrogen-vacancy center at 637 nm.

Photorefractive Resonance Tuning and Frequency Conversion in a Diamond Nanocavity

Joe Itoi, Elham Zohari, Waleed El-Sayed +3 more

Weak optical nonlinear interactions can be greatly enhanced by tight confinement and recirculation of light in an optical resonator. In this work, we demonstrated cavity-enhanced strong green third-harmonic generation from a single-crystal diamond photonic crystal nanocavity. Furthermore, we observe a novel photorefractive resonance blue-shift of the cavity, arising from charge excitation by intense IR pump photons and generated third-harmonic photons. The resulting photorefractive blue-shift greatly exceeds the cold cavity linewidth.

We demonstrate cavity-enhanced third-harmonic generation in a diamond photonic crystal cavity. We further show non-volatile blue-shifting of the cavity resonance, by Δω2π=20.9GHz which exceeds the cavity linewidth, attributed to photorefractive effects.
