- Abstract: We present a low-loss, compact, hollow core optical fibre (HCF) cell
integrated with single mode fibre (SMF). The cell is designed to be filled with
atomic vapour and used as a component in photonic quantum technologies, with
applications in quantum memory and optical switching. We achieve a total
insertion loss of 0.6(2) dB at 780 nm wavelength via graded index fibre to
ensure efficient mode matching coupled with anti-reflection coatings to
minimise loss at the SMF-HCF interfaces. We also present numerical modelling of
these interfaces, which can be undertaken efficiently without the need for
finite element simulation. We encapsulate the HCF core by coupling to the SMF
inside a support capillary, enhancing durability and facilitating seamless
integration into existing fibre platforms.
