Abstract
We discuss a new integrated approach to realizing optical quantum interference effects such as electromagnetically induced transparency (EIT), slow light, and highly efficient nonlinear processes on a semiconductor chip. An ensemble of alkali atoms represents one of the canonical systems that exhibit slow light and related phenomena. At the same time, it would be desirable to build slow-light and related devices on a semiconductor platform in order to move to practical applications. We review progress towards combining the large magnitude of quantum interference effects in alkali vapors with the convenience of integrated optics in the form of hollow-core antiresonant reflecting optical waveguides (ARROWs). We discuss the benefits and challenges of this integrated approach with special emphasis on nonlinear optics. We present strategies to optimize the optical waveguides and discuss the current status of building rubidium-filled optical waveguides on a chip. Recent results on optimization of waveguide loss and transfer of rubidium atoms through hollow microchannels on a chip are presented.
