Fiber-Optic Thermal Sensor for TiN Film Crack Monitoring. A titanium nitride (TiN)-coated fiber Bragg grating (FBG) sensor fabricated using an ion beam sputtering system was investigated, and it was found that the produced oxidation at temperatures of 400–500 °C caused a crack. Expand.
To transmit the absolute maximum energy levels down a fiber, the fiber end faces must be absolutely smooth and polished and be perpendicular to the fiber axis and the light beam. Also, the beam diameter should be no greater than approximately one-half of the area of the core (or the diameter of the core).
The basics are firstly introduced to give a clear working principle of an optical fiber as a light waveguide. Then the definitions of the related parameters are described, which include acceptance angle, numerical aperture, refractive index, cut-off wavelength, mode field diameter, spot size etc.

The idea of using light to send messages has been developed since the eighth century b.c., when the Greeks used fire signals for sending alarms or calls for help. A typical Optical Fiber can be either made out of glass (otherwise known as silicon dioxide) or plastic (typically a polysterene or polymethyl methacrylate) Because of the fibers lightness and
Light entering the fiber core through one end at the correct critical angle will bounce back whenever it reaches the boundary between the core and the cladding. This behavior effectively traps light inside the core, allowing the light pulses to propagate through the fiber with minimal loss over long distances.
