Abstract

This paper describes a numerical experiment of design and operation of a fiber coupler between single mode fiber and fiber Bragg grating (FBG). Both components are coupled depending with optical waveguide and source parameters. A characterization of fiber coupler is simulated by varying long grating of 10 mm to 60 mm using transfer matrix method based on coupled mode equation. The wave peak, transmission, and dispersion parameters are analyzed to determine the performance of the fiber coupler. The transmission spectrum showed the wave peaks rise to any increase in the grating length on channel 1 and channel 2. Transmission on channel 1 and channel 2 decreased from the wavelength range of 1.45μm–1.55μm and rised in the range of 1,55μm–1,65μm for each increment in length of grating. The dispersion showed the zero dispersion at specific wavelength for each increase in length of grating. This component can be applied for controlling information signal in wide range communication.

Abstract

Artikel ini membahas arti geometris dari sebuah determinan.  Dengan diketahui sebuah jajargenjang yang dibentuk oleh dua buah vektor kolom suatu matriks, nilai determinan suatu matriks berordo 2x2 dapat diartikan sebagai luas jajargenjang.  Dari sebuah balok atau parallelepiped. yang dibentuk oleh vektor-vektor kolom matriks berordo 3x3dapat diartikan sebagai determinan sebagai volume balok atau  parallelepiped.

Abstract

 Abstrak            Akar-akar persamaan kuadrat  dapat ditentukan dengan 3 metode yaitu pemfaktoran, kuadrat sempurna dan rumus kuadrat. Apabila koefisien pada persamaan kuadrat bernilai besar, akar-akar persamaan kuadrat akan diselesaikan dengan menggunakan rumus kuadrat, karena koefisien yang besar biasanya sulit dilakukan dengan metode pemfaktoran. Pada artikel ini akan dibahas metode lain dalam menyelesaikan akar-akar persamaan kuadrat, yaitu metode transformasi dan metode dengan melibatkan nilai diskriminan persamaan kuadrat. Kata kunci: Persamaan Kuadrat, Akar-akar Persamaan kuadrat, Pemfaktoran

Abstract

Abstract—To construct a scheme of implicit Runge-Kutta methods, there are a number of coefficients that must be determined and satisfying consistency properties and Butcher’s simplifying assumptions. In this paper we provide the numerical simulation technique to obtain a scheme of 10th order Implicit Runge-Kutta (IRK10) method. For simulation process, we construct an algorithm to compute all the coefficients involved in the IRK10 scheme. The algorithm is implemented in a language programming (Turbo Pascal) to obtain all the required coefficients in the scheme. To show that our scheme works correctly, we use the scheme to solve Hénon-Heiles system.Keywords—ODEs, 10th order IRK method, numerical technique, Hénon-Heiles system

Abstract

The development of telecommunications networks is currently dominated by fiber optics. The fiber optic has become a waveguide medium transmitting information with high frequency bands, high capacity and high speed. An optical amplifier is required to maintain electromagnetic signals when they propagate in far distance. One of the amplifiers, Fiber Raman Amplifiers (FRA) which is the light scattering from the light that comes with the phonon in the lattice of amplification medium produces photons that are coherent with the incoming photons. Many amplifiers are commonly used but the problems not only come from the amplifier but also the component circuit and system.  By simulation method, FRA circuit is designed and operated in the form of pre-amplifiers to maintain a better signal from material interference and geometry. The simulation results show that the lowest BER value and the highest Q-factor are found at a distance of 10km depicted by eye diagram.
