A broadband amplified spontaneous emission (ASE) generation in 1880-nm region is demonstrated by employing a newly developed single-mode Tm-Bi codoped fiber (TBF) in conjunction with 793-nm pumping for the first time. The TBF was obtained by drawing a preform, which was fabricated using a deposition of porous layer by the modified chemical vapor deposition(More)
A wideband spectrum-sliced amplified spontaneous emission (ASE) source operating in 1900-nm region is demonstrated using a newly developed double-clad ytterbium-sensitized thulium-doped fiber (YTF) and a Sagnac loop mirror. The YTF used was drawn from a D-shape preform, which was fabricated using the modified chemical vapor deposition (MCVD) and solution(More)
This paper focuses on the design of embroidered textile antenna, where a fractal technology is used to integrate. Modern telecommunication systems require an antenna with low cost of fabrication and low profile features. This has initiated antenna research in various directions and one of them is wearable textile antenna. A wearable antenna is meant to be a(More)
A 1901.6-nm laser is demonstrated using the newly developed double-clad ytterbium-thulium-doped fiber (YTDF) samples in conjunction with 931-nm pumping through the transition of thulium ion from <sup>3</sup>F<sub>4</sub> to <sup>3</sup>H<sub>6</sub> with the assistance of ytterbium to thulium-ion energy transfer. The YTDF used was drawn from a D-shape(More)
We successfully demonstrated a simple, compact and low cost passive Q-switched Thulium doped fiber laser (TDFL) at long wavelength of 1854.3 nm regions in conjunction with 1552 nm pump excitation. A stable pulse has been generated using graphene film based saturable absorber (SA). The graphene is synthesized by electrochemical exfoliation of graphite at(More)
A Tm<sup>3+</sup>/Yb<sup>3+</sup> doped fiber laser (TYDFL) using two different types of cladding shapes fiber was demonstrated. The fiber consists of a fabricated D-shaped cladding and circular cladding fiber with a double clad structure. The difference in the ratio of ions concentration between doped ions for both fibers resulted in different lasing(More)
In this paper, we report a wideband spectrum sliced ytterbium sensitized thulium doped fiber at 2 micron wavelength region. This result was achieved using a simple fiber loop mirror formed by a 2.6 m PMF fiber and a directional coupler. The wide-band spectrum sliced ASE is demonstrated using a 915nm multimode pump ytterbium sensitized thulium doped fiber at(More)
The large mode area Yb<sup>3+</sup>/Tm<sup>3+</sup> co-doped air-clad photonic crystal fiber laser (YTD-PCF) is demonstrated using a fiber Bragg grating (FBG) in a linear cavity resonator. The effect on the performance of the lasing efficiency between the two different doping concentrations of the Yb<sup>3+</sup>/Tm<sup>3+</sup> ions is investigated. The(More)
A simple design of a temperature sensor is proposed and demonstrated using a fiber optic displacement sensor based on an intensity modulation technique. The proposed sensor uses a plastic optical fiber (POF)-based coupler as a probe in conjunction with a flat surface aluminum rod as a target. The aluminum rod is placed within the linear range of the(More)
