Energy-efficient bandwidth enhancement of Brillouin microwave photonic bandpass filters.
Raj P, Parihar R, Dhawan R, Choudhary A. Raj P, et al. Opt Express. 2022 Aug 15;30(17):30739-30749. doi: 10.1364/OE.465813. Opt Express. 2022. PMID: 36242172 Free article.
However, most demonstrated wideband Brillouin-based filters are limited in operation due to the high-power requirements for bandwidth tailoring. We propose a novel approach to realize wideband reconfigurable, Brillouin-based microwave photonic bandpass filters employing RF …

Bandwidth and size limits of achromatic printed-circuit metasurfaces.
Fathnan AA, Powell DA. Fathnan AA, et al. Opt Express. 2018 Oct 29;26(22):29440-29450. doi: 10.1364/OE.26.029440. Opt Express. 2018. PMID: 30470107 Free article.
Since each of these metallic layers is modeled as an impedance, we apply Foster's reactance theorem to determine the bandwidth over which they are physically realizable using passive, causal and lossless structures. We derive limits for the bandwidth and total …

Ground-based measurements of total ozone column amount with a multichannel moderate-bandwidth filter instrument at the Troll research station, Antarctica.
Sztipanov M, Tumeh L, Li W, Svendby T, Kylling A, Dahlback A, Stamnes JJ, Hansen G, Stamnes K. Sztipanov M, et al. Appl Opt. 2020 Jan 1;59(1):97-106. doi: 10.1364/AO.59.000097. Appl Opt. 2020. PMID: 32225282
Combining information from several channels of the Norwegian Institute for Air Research (NILU-UV) irradiance meter, one may determine the total ozone column (TOC) amount. A NILU-UV instrument has been deployed and operated on two locations at Troll research station in Jutu …
