Optical signal generation involves the creation of light signals with specific properties for various applications. This process typically utilizes devices such as lasers, light-emitting diodes or optical modulators to generate optical signals with precise characteristics such as intensity, wavelength, and modulation format. Optical signal generation is crucial in telecommunications, fiber optic communications, optical sensing, and other fields where the transmission of information or the manipulation of light is required. Optical signal analysis relates tothe detection and measurement of optical signals, allowing for assessing the signals quality, identifying impairments, and ensuring reliable transmission. Techniques such as optical spectrum analysis, power measurements, eye diagram analysis, and polarization analysis are typically used to evaluate characteristics such as power levels, spectral content, modulation depth, bit error rate, and polarization state.
