Extinction ratio
text:
In telecommunications, extinction ratio (re) is the ratio of two optical power levels of a digital signal generated by an optical source, e.g., a laser diode. The extinction ratio may be expressed as a fraction, in dB, or as a percentage. It may be given by
- r e = P 1 P 0, where P1 is the optical power level generated when the light source is on, and P0 is the power level generated when the light source is off. The polarization extinction ratio (PER) is the ratio of optical powers of perpendi
