Split-Beam Spectrophotometers A split beam spectrophotometer contains a beam splitter which channels light along a reference path and a sample path simultaneously to two separate detectors.

The optical beam splitter is one of the fundamental components in the optical telecommunication system. In this paper, the design of a 2×2 multimode interference (MMI) beam splitter using gallium ...

In this paper, a high sensitivity of splicing regions tapered photonic crystal fiber (PCF) Mach-Zehnder interferometric refractive index (RI) sensor is described and experimentally demonstrated.
