Abstract

We demonstrate that defects in diamond break inversion symmetry, by observing cavity-enhanced second-harmonic generation – an otherwise forbidden process. The observed second- and third-harmonic emission follows a clear dependency with cavity de-tuning, indicating a doubly-resonant configuration.

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.

We demonstrate cavity-enhanced second-harmonic generation from a diamond microdisk. By performing multicolor illumination, we show that optical manipulation of nitrogen-vacancy centers strongly affects the second-harmonic signal, indicating a difference in χ(2) between two possible electronic configurations.

Novel nonlinear optics in diamond micro- and nano-cavities

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.

Phonon-Dressed Third-harmonic Generation in Diamond

Jiaoyang Zheng, Guru Khalsa, Jeffrey Moses

We experimentally demonstrate in diamond that third-harmonic generation can be enhanced by orders of magnitude with polarization dependence through assistance from a Raman resonance, in a process analogous to coherent anti-Stokes Raman scattering.
