Fiber Optics Lab (MS-207)

The invention of the laser in 1960 and the fabrication of low-loss optical fibers in 1970 have led to immense growth in Research and development in the general area of Photonics. In particular, fiber optics has revolutionized the communication industry as the most attractive and viable transmission medium for wideband telecommunication, data transmission, and information transfer. This has also led to explosive growth and emergence of many new applications of fiber optics. These include a variety of fiber optic sensors, in-line guided wave components like polarizers, directional couplers, fiber gratings, fiber amplifiers, optical switches, etc. for sensing, instrumentation and optical signal processing. In addition to its tremendous technological importance, fiber optics also provides us with an excellent opportunity to demonstrate and elucidate a large number of physical concepts.
