Optical fibers are made of glass or plastic. Most are about the diameter of a human hair, and they can be many miles long. Light travels along the center of the fiber from one end to the other, and a signal can be applied. Fiber optic systems are superior to metal conductors in many applications. Their biggest advantage is bandwidth. Because of the wavelength of light, signals containing more information can be transmitted than metal conductors (even coaxial conductors

Energy is absorbed in the medium, creating excited states in the atoms. Population inversion is achieved when the number of particles in an excited state exceeds the number of particles in the ground state or less excited states. In this case, a mechanism of stimulated emission can occur and the medium can be used as a laser or optical amplifier.

According to the latest report from IMARC Group, the global fiber laser market will grow at a CAGR of around 8% in 2021-2026. Factors such as rapid industrialization and increasing adoption of advanced technologies to automate various manufacturing processes are among the key factors driving the growth of the fiber laser technology market. In addition to this, fiber lasers are gaining popularity in the healthcare industry due to the growing prevalence of chronic diseases. They are used in settings such as dentistry, photodynamic therapy, and biomedical sensing in the mid-infrared spectrum. Furthermore, with the growing demand for electric vehicles (EVs), the application of fiber lasers in internal combustion engines (ICEs) is expected to increase.

An optical fiber sensor is a sensor that converts the state of the measured object into a measurable light signal. The working principle of the optical fiber sensor is to send the incident light beam from the light source into the modulator through the optical fiber. The interaction between the modulator and the external measured parameters determines the optical properties of the light, such as the intensity, wavelength, frequency, phase, polarization state, etc. It changes and becomes a modulated optical signal, which is then sent to the optoelectronic device through the optical fiber and passed through the demodulator to obtain the measured parameters. During the whole process, the light beam is introduced through the optical fiber, passes through the modulator, and then emitted. The role of the optical fiber is first to transmit the light beam, and secondly to act as an optical modulator.

The three principal applications of broadband light sources are as follows. Let’s take a quick look at each one to get a better understanding of them.
