Low Phase Noise Lasers

The main laser parameters are: Amplitude Noise (RIN). Dominates in direct detection scheme particularly in analog systems Frequency or Phase Noise; Frequency Stability; Output Power; Tuning Range (Frequency). In frequency modulation (FM) formats phase or frequency, fluctuations compete with the signal. Reducing these fluctuations increases a signal to noise ratio. A laser signal may be...
