The usage of atomic vapors in technological applications has become increasingly relevant over the past few years. They are utilized e.g. in atomic clocks, magnetometers, as frequency reference or to slow down and store light. Integrated devices which combine photonic structures and thermal atomic vapors on a chip could be an ideal basis for such purposes, as they provide efficient atom-light coupling on a miniaturized scale well beyond the diffraction limit.
After having investigated various types of waveguides on the D1 line in Rubidium,
now we want to use a three level ladder scheme featuring optical access to telecom photons. By this, we are able to use Si as waveguide material instead of Si3N4.
