“…This is consistent with the hypothesis discussed in Ref. [70] that UV-enhanced deposition of hydrocarbons onto the cavity mirrors degrades the finesse. In spite of this larger increase in the loss than in Ref.…”

“…In spite of this larger increase in the loss than in Ref. [70], the rate of the loss increase is still low enough to maintain the high finesse over the time scale of many years. This atomic ensemble near a mirror surface without excessive contamination is suitable for performing a wide variety of cQED experiments in the strong-coupling regime, where η > 1.…”

Trapping Yb171 atoms into a one-dimensional optical lattice with a small waist

In most experiments with atoms trapped in optical lattices, the transverse size of the optical lattice beams is of the order of tens of micrometers, and loading many atoms into smaller optical lattices has not been carefully investigated. We report trapping 1500 171 Yb atoms in a one-dimensional optical lattice generated by a narrow cavity mode at a distance of 0.14 mm from a mirror surface. The simplest approach of loading atoms from a mirror magneto-optical trap overlapped with the cavity mode allows the adjustment of the loading position by tuning a uniform bias magnetic field. The number of atoms trapped in the optical lattice exhibits two local maxima for different lattice depths, with a global maximum in the deeper lattice. These results open a way to quantum mechanical manipulation of atoms based on strong interaction with a tightly focused light field.

“…From the measured finesse of F = 4700 ± 700 we estimate the losses of the mirrors to be L = (350 ± 100) ppm, in agreement with the manufacturer's expectation. Similar to our previous work on ultraviolet cavities 40 , the losses have remained constant over time even under ultrahigh vacuum conditions. With a cavity length of (261 ± 1) μm we calculate a mode waist (1/e 2 intensity radius) of ω cavity = 4.1(2) μm.…”

The development of efficient network nodes is a key element for the realization of quantum networks which promise great capabilities as distributed quantum computing or provable secure communication. We report the realization of a quantum network node using a trapped ion inside a fiber-based Fabry–Perot cavity. We show the generation of deterministic entanglement at a high fidelity of 90.1(17)% between a trapped Yb ion and a photon emitted into the resonator mode. We achieve a success probability for generation and detection of entanglement for a single shot of 2.5 × 10−3 resulting in 62 Hz entanglement rate.

Fabry–Perot interferometers have stimulated numerous scientific and technical applications ranging from high-resolution spectroscopy over metrology, optical filters, to interfaces of light and matter at the quantum limit and more. End facet machining of optical fibers has enabled the miniaturization of optical Fabry–Perot cavities. Integration with fiber wave guide technology allows for small yet open devices with favorable scaling properties including mechanical stability and compact mode geometry. These fiber Fabry–Perot cavities (FFPCs) are stimulating extended applications in many fields including cavity quantum electrodynamics, optomechanics, sensing, nonlinear optics and more. Here we summarize the state of the art of devices based on FFPCs, provide an overview of applications and conclude with expected further research activities.
