\nAbstract. The optical sensing devices has been fabrication based on D-Shaped Fiber coated with Graphene Oxide (GO).
\nThe single mode Step Index fiber (SMF-28) used resemble (D-Shaped Fiber) to generate an evanescent field on polishing
\narea used as optical sensing region with (2mm2) area. This technique applying few layers (~22-layers) of Graphene
\nOxide (GO) with a thickness of ~ 0.09~\u03bcm used to coat D-shaped fiber. The performance D-Shaped Fiber have been test
\nby applied different elements on polished region (without GO- coat and with GO-coat) that show increase in transmitted
\npower by ~3.5dBm and ~21.5dBm respectively. The COMSOL Multiphasic simulation using to perform the effect of
\nphishing on the electric field of sensing region. These features can make D-Shaped-Fiber can be used in many
\napplications such as biomedical sensor, humidity sensor, temperature sensor and biochemical sensor.
