Recently, there has been a growing interest in waveguides with hollow cores. This is in large part due to the fact that guiding light through non-solid media such as liquids or gases allows access to a large number of fields beyond traditional integrated optics for data communications.

 

We have developed a new approach to this field based on antiresonant reflecting optical waveguides (ARROWs). These waveguides can be built using a standard microfabrication process on a silicon chip and have the potential for a variety of applications relying on ultrahigh sensitivity.

 

In this talk, I will review the physical principle and fabrication of hollow-core ARROWs. I will then describe their application to two very different fields of single particle studies: single-photon nonlinear optics and single-molecule spectroscopy. In particular, I will discuss the first integrated rubidium cell on a chip and the detection and manipulation of single biomolecules in an ARROW-based optofluidic device.
