Polarization based modulation of splitting ratio in femtosecond laser direct written directional couplers
Zhi-Kai Pong, Bangshan Sun, Patrick S. Salter +1
This work characterizes a phenomenon in direct laser written directional couplers where the splitting ratio for output light is dependent on the input polarization state. In genera…
A reconfigurable arbitrary retarder array as complex structured matter
Chao He, Binguo Chen, Zipei Song +31
Tuneable retarder arrays, such as spatially patterned liquid crystal devices, have given rise to impressive photonic functionality, fuelling diverse applications ranging from micro…
High-precision optical fiber sensing beyond 1000°C
Mohan Wang, Patrick S. Salter, Frank P. Payne +10
Sapphire fiber can withstand around 2000°C, but it is multimoded, giving poor precision sensors. We demonstrate a single-mode sapphire fiber Bragg grating temperature sensor operat…
High Speed Precise Refractive Index Modification for Photonic Chips through Phase Aberrated Pulsed Lasers
Bangshan Sun, Simon Moser, Alexander Jesacher +3
Integrated photonic chips have significant potential in telecommunications, classic computing, quantum systems, and topological photonics. Direct laser writing offers unique capabi…
Additive GaN solid immersion lenses for enhanced photon extraction efficiency from diamond color centers
Xingrui Cheng, Nils Kolja Wessling, Saptarsi Ghosh +9
Effective light extraction from optically active solid-state spin centres inside high-index semiconductor host crystals is an important factor in integrating these pseudo-atomic ce…
