Cold atoms are useful for many quantum information applications. Their strong interactions with light give them many uses in atom-photon junctions. However, one difficulty with cold atoms is integrating them with waveguides and other photonic devices. Here we demonstrate a method that involves trapping the atoms inside a laser drilled hole through an optical fibre. By carefully selecting the geometry of the cavity, one can tune the transmission of light through it, with parabolic convex surfaces having the greatest transmission.
Once the atoms are trapped in the fibre, they can be used to demonstrate many interesting and useful phenomena. Our goal is to demonstrate electromagnetically induced transparency (EIT); which allows not just for control over the transparency of the atoms, but also leads to slow light effects and even photon storage.
