Quantum- and nanooptics with tunable microcavities

David Hunger

Karlsruhe Institute of Technology, Germany

Optical microcavities are a powerful tool to enhance light-matter interactions. This enables applications ranging from ultra-sensitive spectroscopy and sensing to quantum information. To achieve large cavity enhancement on a flexible platform, we have developed microscopic Fabry-Perot cavities based on laser-machined optical fibers.

In the context of sensing, we use microcavities for imaging and spectroscopy applications, as well as for sensing of dynamic properties of individual nanosystems. We have developed scanning cavity microscopy as a versatile method for spatially and spectrally resolved maps of various optical properties of a sample with ultra-high sensitivity. Simultaneous enhancement of absorptive, dispersive, and scattering signals promises intriguing potential for optical studies of nanomaterials, molecules and biological nanosystems.

For quantum information applications, we employ such cavities to realize efficient readout of individual spin-bearing quantum emitters by means of Purcell enhancement of fluorescence emission. We study solid state quantum emitters such as NV centers in diamond and rare earth ions, with the goal to realize a quantum repeater for long-distance quantum communication, and optically addressable multi-qubit registers as quantum computing nodes.

Arcsine laws in an optical cavity

The arcsine laws are an example of emergent statistical structure in nature manifesting in a variety of unrelated physical systems. However, their validity in optical systems has not yet been studied. We investigate the time-integrated intensity in a driven-dissipative linear optical cavity and observe, experimentally and via numerical simulations, that all three arcsine laws are obeyed by this quantity.

We propose a new type of periodic dielectric waveguide that provides strong interactions between atoms and guided photons. We design an asymmetric comb waveguide that supports a slow mode with an unusual quartic dispersion around a zero-group-velocity point and an electric field that extends far into the air cladding for an optimal interaction with atoms. We calculate the potential of a two-color trap made by using blue-detuned and red-detuned guided modes. We show that cold Rubidium atoms can be trapped as close as 100 nm from the structure in a 1.3-mK-deep potential well. Finally, we calculate that, for atoms trapped at this position, the emission into guided photons is largely favored. The radiative decay rate into the guided slow mode is 10 times larger than the free-space decay rate and the beta factor is as high as 0.88

Engineering high Q/V photonic modes in correlated disordered systems

Hyperuniform disordered (HuD) photonic materials have recently been shown to display several localized states with relatively high Q factors arising at the Photonic Band Gap edges. However, their spatial position is not predictable a priori. Here we experimentally benchmark through near-field spectroscopy, capable of sub-wavelength resolution in the near-IR range, the engineering of high Q/V resonant modes in a defect inside a HuD luminescent pattern. These deterministic modes, coexisting with Anderson-localized modes, have never been experimentally realized so far and are a valid candidate for implementations in optoelectronic devices due to the spatial isotropy of the HuD environment upon which they are built.

Exceptional Precision of a Nonlinear Optical Sensor at a Square-Root Singularity

Kevin Peters, Said Rodriguez

Center for Nanophotonics, AMOLF, Science Park 104, 1098 XG Amsterdam, The Netherlands

We demonstrate a nonlinear optical resonator with exceptional sensitivity in noisy environments. Our sensor is a hysteretic resonator, which displays a signal with a square-root singularity where the sensitivity, precision and information content are enhanced.
