In this article a two-ports nonlinear fiber Mach-Zehnder interferometer is proposed. The expression for output-input intensity relation and the transmittance function are derived based on principle operation of optical coupler. The expression of coupling ... see more

In this article, the dependence of bistability characteristic of the two-port nonlinear fiber Mach-Zehnder interferometer (TPNFMZI) on initial phase shift, wavelength of input signal, nonlinear coefficient of refractive index and length of nonlinear fiber... see more

This study aims to determine the specific needs, feasibility, and responses of teachers and students toward the developed physics learning media of monopoly game on the light and optical devices material. The research procedure was based on the 4-D model.... see more

This research aims to produce the teaching materials based on the inquiry learning model with valid, effective, and practical crossword puzzle of a physics lesson, especially in the optical appliance material of junior high school. The type of this resear... see more

Couplers and splitters are common devices in single-mode and multi-mode glass fibers applications, where they perform a variety of functions. However, when switching to plastic optical fibers (POFs), there is a shortage of commercial devices, which are us... see more

In this article, the reshaping of the series of sinuous pulses and Gaussian pulses with arbitrary amplitude of laser signal by two-port nonlinear fiber Mach-Zehnder interferometer are simulated. The output series of close to flat-form pulses of laser sign... see more

This article aims to evaluate the optical behavior of a small handmade prototype of a linear Fresnel concentrator (LFC). The system was developed and tested as a water heater and steam generator at the Unidades Tecnológicas de Santander university, locate... see more

This paper investigated the structural, optical, electronic and thermal characteristics of SrSnO3 perovskites that were calculated using the density functional theory. Software called WEIN2K is used to perform the calculation. According to our calculation... see more

We investigate the behavior of optical bistability in a degenerate two-level atomic medium using an external magnetic field to separate the lower level into two distinct levels that both connect to an upper level by the probe and coupling laser fields. Ba... see more
