Laser-written integrated photonics in glass-ceramics Zerodur
Jun Guan, Martin J. Booth
We demonstrated fabrication of waveguide and directional coupler in bulk glass-ceramics Zerodur, through femtosecond laser direct-writing. Waveguide propagation loss of no more tha…
A Photonic Topological Mode Bound to a Vortex
Adrian J Menssen, Jun Guan, David Felce +2
Topological photonics sheds light on some of the surprising phenomena seen in condensed matter physics that arise with the appearance of topological invariants. Optical waveguides…
Ultrafast laser writing quill effect in low loss waveguide fabrication regime
Jun Guan, Xiang Liu, Martin J. Booth
Quill effect, one of the intriguing phenomena in ultrafast laser writing, to our knowledge, has not been studied in low-loss-waveguide (LLW) writing regime yet, probably due to its…
Microscopic characterisation of laser-written phenomena for component-wise testing of photonic integrated circuits
Jun Guan, Xiang Liu, Adrian J. Menssen +1
Photonic integrated circuits (PICs) directly written with a femtosecond laser have shown great potential in many areas such as quantum information processing (QIP). Many applicatio…
Splitting of self-collimated beams in two-dimensional sonic crystals
Bo Li, Jun-Jun Guan, Ke Deng +1
An easy-to-implement scheme to split self-collimated acoustic beams in sonic crystals (SCs) is proposed by introducing line-defects into SCs, by which an incoming self-collimated b…
