| 1 | Ultra-high suppression microwave photonic bandstop filters显示文摘A bandstop radio frequency(RF)filter can enhance the capabilities of RF communication systems by removing unwanted signal components such as distortion,or interference.In modern cognitive radio systems,frequency agile filters are desired to block interferers with dynamically changing frequencies and powers.These filters should be tunable over a broad frequency range,and they should be capable of suppressing very strong signals with a high resolution.To simultaneously meet these requirements with traditional RF filters are highly challenging.Microwave photonic(MWP),a technology that primary deals with the generation,distribution,and processing of high speed RF signals using photonic techniques and components,is promising for creating frequency agile RF filters.However,traditional MWP filters are lacking the high resolution and peak suppression exhibited by state-ofthe-art RF electrical filters.We recently introduced a new class of MWP notch filter which is free from this limitation.This scheme allowed the creation of anomalously high suppression MWP notch filter from virtually any kind of optical resonance,irrespective of its type(gain or absorption),or its magnitude.This enabled,for the first time,simultaneous optimization of the MWP filter resolution,peak attenuation,and frequency tuning range.In this paper,we present the analysis of notch filter response creation using the novel sideband processing technique.We thenshow the applicability of this technique to a wide range of optical filters.We compare simulated and experimental results of the notch filter response created using three types of optical filter commonly used in MWP signal processing,namely stimulated Brillouin scattering(SBS),an integrated optical ring resonator(ORR),and a phase-shifted fiber Bragg-grating(FBG). | David Marpaung Blair Morrison Mattia Pagani Ravi Pant Benjamin J.Eggleton | 2014 | Chinese Science Bulletin2014，59，22： | 3 |

| 19 | Integrated adsorption and photocatalytic removal of methylene blue dye from aqueous solution by hierarchical Nb_(2)O_(5)@PAN/PVDF/ANO composite nanofibers显示文摘This work presents the development of hierarchical niobium pentoxide(Nb_(2)O_(5))-based composite nanofiber membranes for integrated adsorption and photocatalytic degradation of methylene blue(MB)pollutants from aqueous solutions.The Nb_(2)O_(5) nanorods were vertically grown using a hydrothermal process on a base electrospun nanofibrous membrane made of polyacrylonitrile/polyvinylidene fluoride/ammonium niobate(V)oxalate hydrate(Nb_(2)O_(5)@PAN/PVDF/ANO).They were characterized using field-emission scanning electron microscopy(FE-SEM),X-ray diffraction(XRD)analysis,and Fourier transform infrared(FTIR)spectroscopy.These composite nanofibers possessed a narrow optical bandgap energy of 3.31 eV and demonstrated an MB degradation efficiency of 96%after 480 min contact time.The pseudo-first-order kinetic study was also conducted,in which Nb_(2)O_(5)@PAN/PVDF/ANO nanofibers have kinetic constant values of 1.29×10^(-2) min^(-1) and 0.30×10^(-2) min^(-1) for adsorption and photocatalytic degradation of MB aqueous solutions,respectively.These values are 17.7 and 7.8 times greater than those of PAN/PVDF/ANO nanofibers without Nb_(2)O_(5) nanostructures.Besides their outstanding photocatalytic performance,the developed membrane materials exhibit advantageous characteristics in recycling,which subsequently widen their practical use in environmental remediation applications. | Aditya Rianjanu Kurniawan Deny Pratama Marpaung Elisabeth Kartini Arum Melati Rizky Aflaha Yudha Gusti Wibowo I Putu Mahendra Nursidik Yulianto Januar Widakdo Kuwat Triyana Hutomo Suryo Wasisto Tarmizi Taher | 2024 | Nano Materials Science2024，6，1： | 0 |
| 20 | Low-loss microwave photonics links using hollow core fibres显示文摘There are a host of applications in communications, sensing, and science, in which analogue signal transmission is preferred over today’s dominant digital transmission. In some of these applications, the advantage is in lower cost, while in others, it lies in superior performance. However, especially for longer analogue photonics links (up to 10 s of km), the performance is strongly limited by the impairments arising from using standard single-mode fibres (SSMF). Firstly, the three key metrics of analogue links (loss, noise figure, and dynamic range) tend to improve with received power, but this is limited by stimulated Brillouin scattering in SSMF. Further degradation is due to the chromatic dispersion of SSMF, which induces radio-frequency (RF) signal fading, increases even-order distortions, and causes phase-to-intensity-noise conversion. Further distortions still, are caused by the Kerr nonlinearity of SSMF. We propose to address all of these shortcomings by replacing SSMFs with hollow-core optical fibres, which have simultaneously six times lower chromatic dispersion and several orders of magnitude lower nonlinearity (Brillouin, Kerr). We demonstrate the advantages in this application using a 7.7 km long hollow-core fibre sample, significantly surpassing the performance of an SSMF link in virtually every metric, including 15 dB higher link gain and 6 dB lower noise figure. | Xi Zhang Zitong Feng David Marpaung Eric Numkam Fokoua Hesham Sakr John Richard Hayes Francesco Poletti David John Richardson Radan Slavík | 2022 | Light(Science & Applications)2022，11，8： | 0 |
