Photorefractive resonance tuning and frequency conversion in a diamond nanocavity

Abstract

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.

Photorefractive Resonance Tuning and Frequency Conversion in a Diamond Nanocavity

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.

Photorefractive tuning seeded by third-harmonic light in a diamond photonic crystal cavity

Joe Itoi, Elham Zohari, Nicholas J. Sorensen +6 more

Single-crystal diamond nanocavities have tremendous potential for use in quantum and nonlinear optical technologies. The ability to precisely control their resonant frequencies is essential for many applications, and in situ tuning is particularly desirable. In this work, we demonstrate deterministic resonance tuning of a diamond nanocavity. We observed a photorefractive effect in concert with the generation of third-harmonic light within the device. This effect blue-shifted the cavity resonance frequency by 20.2 (2) GHz, exceeding the cavity linewidth. The shift corresponded to a fractional change in refractive index of −1.05(1)×10 −4 , and its relaxation occurred over several tens of hours. Although photorefraction is a second-order nonlinear effect and has previously not been observed in diamond owing to its vanishing χ (2) , the observed behavior is consistent with the generation of non-zero χ (2) by electric fields from charged crystal defects. In addition to allowing tuning of diamond cavities for resonant nonlinear and quantum photonics applications, this observation could enable the realization of diamond frequency converters and electro-optical modulators that rely on second-order nonlinearity.

Doubly-resonant diamond cavities can be used to enhance nonlinear processes. We present a photorefractive tuning mechanism and demonstrate blue-shifting of an optical mode by 26 nm, allowing for the realisation of doubly-resonant diamond cavities post-fabrication.

Novel nonlinear optics in diamond micro- and nano-cavities

Sigurd Flågan, Joe Itoi, Elham Zohari +7 more

Diamond constitutes a promising material platform for a myriad of photonic applications. In this work, we demonstrate several novel nonlinear optical phenomena in fibre-taper coupled diamond micro and nanocavities. Central to these observations are ensembles of nitrogen-vacancy (NV) centres native to the diamond devices. We first show photoinduced modifications of second-harmonic generation (SHG) from a microdisk, and demonstrate, for the first time, that the strength of the SHG strongly depends on the charge state of the NV centres. Illuminating the microdisk with a green laser quenches the SHG signal. Removing the green laser recovers the original SHG signal, allowing for deterministic optical switching of the device’s χ(2). We next show strong photorefractive blue-shifting of the resonance frequency in a diamond photonic crystal cavity. The total frequency shift exceeds the intrinsic linewidth, corresponding to a fractional change in refractive index of ∼ −10−4.

Nonlinear Optics in a Diamond Micro- and Nano-Cavities

Resonant recirculation of light in optical microcavities can greatly enhance light-matter interactions. In this work, we demonstrate cavity-enhanced second-harmonic and third-harmonic generation from a single-crystal diamond microdisk. The presence of crystal defects – here nitrogen-vacancy centers – breaks the inversion symmetry of the diamond crystal, allowing for observation of the otherwise forbidden second-harmonic generation. We further show that the photon emission follows a clear dependency with cavity detuning of both the pump and emission modes, a clear indication of a doubly-resonant configuration.
