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…
Topologically controlled multiskyrmions in photonic gradient-index lenses
Yijie Shen, Chao He, Zipei Song +8
Skyrmions are topologically protected quasiparticles, originally studied in condensed-matter systems and recently in photonics, with great potential in ultra-high-capacity informat…
Single-mode sapphire fiber Bragg grating
Mohan Wang, Patrick S. Salter, Frank P. Payne +4
We present here the inscription of single-mode waveguides with Bragg gratings in sapphire. The waveguide Bragg gratings have a novel multi-layer depressed cladding design in the 15…
On-chip beam rotators, adiabatic mode converters, and waveplates through low-loss waveguides with variable cross-sections
Bangshan Sun, Fyodor Morozko, Patrick S. Salter +14
Photonics integrated circuitry would benefit considerably from the ability to arbitrarily control waveguide cross-sections with high precision and low loss, in order to provide mor…
Active metamaterials with negative static electric susceptibility
F. Castles, J. A. J. Fells, D. Isakov +3
Well-established textbook arguments suggest that static electric susceptibility must be positive in "all bodies" [1]. However, it has been pointed out that media that are not in th…
