Photonic stepped-frequency radar with 150-m unambiguous detection and centimeter range resolution
Photonic stepped-frequency radars based on optical frequency-shifting modulation have shown attractive properties such as wide bandwidth, centimeter range resolution, inherent frequency-time linearity with low spectrum spurs, and reduced system complexity. However, existing approaches typically exhibit meter- or centimeter-level radar range ambiguity, inversely proportional to the frequency step, due to the large frequency shift determined by acousto-optic or electro-optic (EO) modulators.
Bragg Solitons - Historical and Future Perspectives (Laser Photonics Rev. 17(12)/2023)
Graphical Abstract Bragg Solitons – Historical and Future Perspectives In article number 2300373, Dawn T. H. Tan and Benjamin J. Eggleton review the history of Bragg solitons, followed by recent progress made in integrated photonic devices, facilitated by recent advancements in the design and fabrication of on-chip Bragg gratings.
Bragg Solitons - Historical and Future Perspectives
Solitons have been a subject of intense intellectual curiosity and an avenue for a plethora of applications since they are first observed in water waves. Optical solitons, in particular, have seen tremendous progress, starting from their first theoretical predictions in optical fiber in 1973. On the 50th anniversary of this seminal work from Haseagawa and Tappert, a review is provided on the progress in an important class of optical solitons, the Bragg soliton.
Research priorities for COVID-19 sensor technology
To the Editor — The COVID-19 pandemic has spurred efforts to develop sensor technology to manage the disease1,2,3. Most of these projects have been driven by medical researchers, scientists and engineers without explicit involvement and input from patients and the broader community. Here, we define sensor technology broadly to include physical, cellular and molecular platforms that produce signals to identify specific events associated with SARS-CoV-2 and/or its interaction with the host.

Low-RF-loss and large-rejection reconfigurable Brillouin-based RF photonic bandpass filter
Abstract We present a high-performance radio frequency (RF) photonic bandpass filter enabled by combining on-chip Brillouin scattering with a suppressed carrier phase modulation scheme. We achieve a low RF loss of 5 dB and a large stopband rejection of more than 40 dB, which represents a significant improvement of 20 dB to the RF passband gain and 31 dB to the RF rejection ratio over traditional modulation schemes under the same optical power consumption.

Brillouin integrated photonics
Abstract A recent renaissance in Brillouin scattering research has been driven by the increasing maturity of photonic integration platforms and nanophotonics. The result is a new breed of chip-based devices that exploit acousto-optic interactions to create lasers, amplifiers, filters, delay lines and isolators.
Introduction to the APL Photonics editorial series on the future of photonics
Abstract This editorial serves as an introduction to a forthcoming series of editorials by the editors of APL Photonics on the future of the broad field of photonics. The Editor-in-Chief lays out some of the recent progresses, major trends, and perspectives on the future for the broader field as he sees them and briefly introduces the topics of the first several upcoming editorials by the associate editors. These editorials aim to promote multidisciplinary conversation to push the field forward. I.

Observation of Eisenbud-Wigner-Smith states as principal modes in multimode fibre
Generally, light becomes scattered in space and time as it is coupled among multiple spatial paths during propagation through disordered media or multimode waveguides. This limits the pulse duration and spatial coherence that can be obtained after light exits such a medium. Eisenbud–Wigner–Smith eigenstates, originally proposed in nuclear scattering, are a unique set of input/output states that, despite spatiotemporal scattering during propagation, arrive at the output temporally unscattered.

Speed Plus Control In New Computer Chip - Slowing Down Light To Sound
Light travels fast – sometimes a little too fast when it comes to data processing. Published today, our paper describes a new memory chip design that allows us to temporarily slow down light to a manageable speed for better control of computer processing. Light packets were successfully stored as high-pitch sound waves – about 1,000 times higher than ultrasound – in a wire on a microchip.

Small and bright: what nanophotonics means for you | Manufacturers Monthly
Twenty fifteen was UNESCO’s International Year of Light and Light based Technologies. It was a celebration of past milestones in optics and photonics and a look forward into it’s future. We celebrated 1,000 years of Arabic optics, 150 years since James Maxwell’s electrodynamics, 100 years since Albert Einstein’s general relativityand 50 years since the invention of optical fibres. This year we celebrate 100 year since Claude Shannon, who introduced the theory of information, was born.
