Hollow-core optical fibers (HCFs) have unique properties like low latency, negligible optical
nonlinearity, wide low-loss spectrum, up to 2100 nm, the ability to carry high power, and …

In this paper, we report the use of a 3-meter low-loss anti-resonant hollow-core fiber (AR-
HCF) to deliver up to 300 W continuous-wave laser power at 1080 nm wavelength from a …

We introduce a flexible microscale all-fiber-optic Raman probe which can be embedded into
devices to enable operando in situ spectroscopy. The facile-constructed probe is composed …

Glass optical fibers have reached a scale and commercial maturity that few, if any, other
material and form can claim. Furthermore, optical fibers not only enable a remarkably broad …

Coupled-mode theory is a powerful tool to understand and control the effects of deployment
and fabrication imperfections on optical waveguides. Although it provides many advantages …

Hollow core optical fibers of numerous guiding mechanisms have been studied in the past
decades for their advantages on guiding light in air core. This work demonstrates a new …

We demonstrate high-power laser delivery exceeding 1 kilowatt through a 5-meter
homemade anti-resonant hollow-core fiber (AR-HCF) at 1-µm wavelength. Laser-induced …

We proposed and demonstrated mode cleaning in a high-power fiber laser by integrating an
anti-resonant hollow-core fiber (AR-HCF) into a multimode laser cavity of an ytterbium (Yb) …

We investigate the design of hollow-core fibers for the delivery of 10s of kilowatt average
power from multi-mode laser sources where delivery through solid-core fibers is typically …

We propose using an optical fiber-based interferometer to search for scalar ultralight dark
matter (UDM) with particle mass in the range 10-17-10-13 eV/c 2 (10-3-10 Hz). Composed of …
