Wavelength division multiplexing refers to a technology in which signals of different wavelengths are transmitted together and separated again. At most, it is used in optical fiber communication to transmit data in multiple channels with slightly different wavelengths. Using this method can greatly improve the transmission capacity of the optical fiber link, and the use efficiency can be improved by combining active devices such as optical fiber amplifiers. In addition to applications in telecommunications, wavelength division multiplexing can also be applied to the case where a single fiber controls multiple fiber optic sensors.

Some laser applications require the laser to have a very narrow linewidth, that is, a narrow spectrum. Narrow linewidth lasers refer to single-frequency lasers, that is, there is a resonant cavity mode in the laser value, and the phase noise is very low, so the spectral purity is very high. Typically such lasers have very low intensity noise.

Erbium doped fiber is the core component of PA amplifiers, which amplifies optical signals by doping the rare earth element erbium (Er) into the fiber core.

This is a packaged chip with integrated circuits composed of tens or tens of billions of transistors inside. When we zoom in under a microscope, we can see that the interior is as complex as a city. The integrated circuit is a kind of miniature electronic device or component. Together with wiring and interconnection, fabricated on a small or several small semiconductor wafers or dielectric substrates to form structurally closely connected and internally related electronic circuits. Let’s take the most basic voltage divider circuit as an example to illustrate that it is How to realize and produce effect inside the chip.
