An optical fiber grating coupler (FGC) is a fused optical fiber coupler with a tapered region in which refractive index-modulated gratings are written. In the FGC, the light with specific wavelength satisfying the Bragg condition of the grating can be dropped to one output port and other lights are

## Abstract There is increasing motivation to develop sensors and actuators to manage domestic electric power consumption. This article demonstrates an optical fiber sensor using a superstructure fiber grating (SFG) to measure electric power consumption. The sensor head is based on SFG encapsulated
## Abstract In this article, the output spectrum have been numerically analyzed in order to investigate the temperature characteristics of the allβoptical add/drop multiplexer. It is shown that the center Bragg wavelength shifts by about 0.014223 nm when the temperature increases by 1Β°C in a range
