Laser-written scalable sapphire integrated photonics platform
Mohan Wang, Patrick S. Salter, Frank P. Payne +3
In this paper, we demonstrate the integration of photonic devices on sapphire substrates using multi-layer depressed cladding waveguides at both 780 nm and 1550 nm. The devices are…
Intensity adaptive optics
Zimo Zhao, Yifei Ma, Zipei Song +12
Adaptive optics (AO) is a powerful tool employed across various research fields, from aerospace to microscopy. Traditionally, AO has focused on correcting optical phase aberrations…
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…
