Abstract

In accordance with the principle of the technique based on Fresnel reflection, reflectivity of a dielectric surface depends on the difference of refractive indices of the surface and the surrounding medium, and the reflection coefficient is defined as the ratio of the reflected light power to the incident light power. In the investigations reported, the amount of back reflected light at one of the output ports of a 2 × 2 single-mode optical-fiber coupler due to Fresnel reflection was monitored by means of a high sensitivity …
