Definition: A laser that uses a doped fiber as a gain medium, or a laser whose laser resonator is mostly composed of fiber.

The grating coupler uses grating technology to couple optical signals into optical fibers, and uses the principle of grating diffraction to connect the transmitted optical signals with the optical field inside the optical fiber.

Fiber Bragg gratings are optical components with a periodic structure that separate light into beams that propagate in predictable directions based on wavelength. Gratings serve as the core dispersive element of many modern spectroscopic instruments.

Thermistors are mainly used for temperature monitoring, overheating protection, etc. It is a temperature-sensitive semiconductor resistor whose resistance changes significantly with changes in temperature. It uses the heat-sensitive effect of semiconductor materials to measure and control temperature, and is widely used in various electronic devices and systems. Thermistors hav...

Wavelength (common units: nm to µm):  The wavelength of a laser describes the spatial frequency of the emitted light wave. The optimal wavelength for a specific use case depends heavily on the application. During material processing, different materials will have unique wavelength absorption characteristics, resulting in different interactions with the materials. Likewise, at...
