We report the point-by-point inscription of gratings in lithographically fabricated polymer ridge waveguides using direct-write laser processing. This device exhibited narrow-band-pass spectral features of ∼ 0.8 nm full-widthhalf-maximum, suitable for wavelength division multiplexing applications. PACS 52.38.Mf; 81.16.-c; 42.79.Gn

Abstract The publication of a hieroglyphic inscription found at Türkmenkarahöyük in the Konya region and associated survey-work area have raised numerous questions about location city Tarhuntassa, aftermath Hittite Empire dating Hieroglyphic inscriptions which mention king called Hartapu. In this paper we review evidence for Tarhuntassa that deem relevant deciding whether it could been situated...

Le zinc et le cuivre sont des éléments-traces métalliques (ÉTM) qui peuvent présenter à plus ou moins long terme un risque environnemental pour les sols agricoles sur lesquels valorisées déjections porcines. Ces ÉTM essentiels la croissance santé porcs en élevage, ils donc ajoutés dans l’aliment sous forme de supplémentation. Cependant, du fait leur faible taux rétention chez porc, se retrouven...

This paper offers the editio princeps of a Greek inscription engraved on marble column discovered in ‘Saranda Kolones’ Castle at Nea Paphos Cyprus. The inscription, dated to second or early third century AD, contains names otherwise unknown Tiberius Claudius Claudianus Hetereianus, member ordo equester, founder column. is only known mentioning name Hetereianus. It remains an open question as wh...

To further improve the hydrophobic and thermal properties of fluorinated polyurethane (FPU), we initially prepared fluorine- silicon-containing pendant groups’ diols (DEFA DESiA) by Michael addition reaction. Next, synthesized a series co-modified nanocomposite (TPFPU-SiO2) latexes terminal fluoroalkyl segments via varying additive amount silica sols. Structure performance target materials were...

of PhD thesis In this thesis report, both fiber Bragg grating (FBG) photo-inscriptions in polymer optical fibers (POFs) and their sensing applications are discussed. During my thesis work, only poly(methyl methacrylate) (PMMA) POFs were used. They were manufactured at the Hong Kong Polytechnic University. They are characterized by a core diameter of 8.2 μm and a cladding diameter of 150 μm. The...
