Enabling low Threshold Laser Through an Asymmetric Tetramer Metasurface Harnessing Polarization‐Independent Quasi‐BICs

Advanced Optical Materials, EarlyView.
Light impinging from the left on a metasurface composed by active material. The metasurface shows asymmetric configuration through the non‐uniform presence of holes. The forming quasi‐BICs modes are exploited for lasing purposes. Abstract It is proposed and numerically demonstrated a novel strategy to achieve lasing generation from a dual‐band symmetry‐

Harnessing the potential of online marketplaces in the Philippines: Insights from the National Information and Communications Technology Household Survey

Asia &the Pacific Policy Studies, Volume 9, Issue 3, Page 288-316, September 2022., 2022
Abstract Using the Philippinesʼ first nationally representative survey designed to characterise digital commercial and non‐commercial engagements, including the use of information and communications technology (ICT), the digital economy, and technology‐enabled activities, we investigate the presence of gendered disparities in online marketplaces.

High Fidelity Waveguides Through Vitreous Media Recomposition for Next Generation Photonic Devices

Advanced Optical Materials, EarlyView.
A newly designed aluminosilicate glass enables the fabrication of femtosecond laser‐written optical waveguides with ultra‐low propagation losses of −0.020 dB cm−1 at 1310 nm and −0.037 dB cm−1 at 1550 nm. Raman, Brillouin, and electron microscopy analyses reveal the mechanisms behind refractive index modifications, highlighting the role of glass ...

Internet usage among women‐led micro and small enterprises and household membersʼ use of the internet at home: Evidence from Indonesia during the COVID‐19 pandemic

Asia &the Pacific Policy Studies, Volume 9, Issue 3, Page 370-393, September 2022., 2022
Abstract This study examines whether internet usage among micro and small enterprises (MSEs) could influence household membersʼ use of the internet in terms of intensity as well as usage for productive activities. Using longitudinal data from MSEs in Yogyakarta, Indonesia, covering the period before and during the COVID‐19 pandemic, the study finds ...

Biphoton Waveforms of Photon Pair from Velocity‐Selective Atoms in a Doppler‐Broadened Atomic Ensemble

Advanced Photonics Research, EarlyView.
Telecom‐band quantum light sources have significant practical applications in this domain. This study reports the high‐performance telecom‐wavelength biphoton generation from a hot vapor cell of 87Rb. For the first time, the beat phenomenon in the autocorrelation function of the signal photon with telecom wavelength due to the velocity‐selective ...

Search Result Clustering via Randomized Partitioning of Query-Induced Subgraphs

, 2008
In this paper, we present an approach to search result clustering, using partitioning of underlying link graph. We define the notion of "query-induced subgraph" and formulate the problem of search result clustering as a problem of efficient partitioning ...

On the Performance of FSO Communications Links under Sandstorm Conditions [PDF]

12th International Conference on Telecommunications - ConTEL 2013, June 26-28, 2013, Zagreb, Croatia. ISBN: 978-1-4673-5984-9 pp. 53-58, Publisher IEEE, 2015
In this paper we focus in the analysis of the FSO link performance under sandstorms conditions. The sandstorms are characterized by the size of the particles and the necessary wind speed in order to blowing them up during a minimum period of time. Sandstorm is a well know problem in many parts of the world and different reports has been presented ...
