Quantum nonlinear optics using cold atomic ensembles
… by loading ensembles of cold atoms in a hollow-core photonic crystal fiber to enhance the polariton-photon interactions. In our second approach, the photons are coupled to strongly interacting Rydberg atoms, which mediate large interactions between single quanta of light. Moreover, the …

Photoacoustic photonic crystal fiber gas sensor
… used as an acoustic resonator. In recent times, hollow-core photonic crystal fiber (HC-PCF) has emerged as superior gas cell for standard absorption-based laser spectroscopy due to its small size, compatibility with fiber-based optical components, and easily attainable long light-gas interaction …

Acetylene-filled pressure broadened short photonic microcells
We have developed short acetylene-filled photonic microcells (PMCs’) as optical frequency references in the near infrared region for applications in telecommunication, gas sensing, and metrology. The PMC is a 5-10 cm long hollow-core photonic crystal fiber (HC-PCF) in which the high pressure …

Using saturated absorption spectroscopy on acetylene-filled hollow-core fibers for absolute frequency measurements
… most setups to date have occurred in free-space. Hollow-core photonic crystal fibers offer a potential alternative to free-space setups through their small cores (~10’s of µm) and low-loss guidance. Furthermore, HC-PCF can be made into fiber cells that could be directly integrated into existing …

Protein Biophysics in Hollow-Core Photonic Crystal Fibres: Label-Free Monitoring of Biomolecules in Optofluidic Waveguides
… In this PhD dissertation, we study the use of hollow-core photonic crystal fibre (HC-PCF), a class of optofluidic waveguides, to optically detect and monitor proteins in microfluidic environments without labels. Within this waveguiding microfluidic fibre geometry, we monitor the label-free …
