To solve the problem, Charlet perfected a system that uses the polarization and phase of a pulse of light, rather than its intensity, to encode data. Errors induced by imperfections are far less problematic thanks to the development of a new receiver that detects the whole electrical field of the signal, rather than just its intensity. As a bonus, each pulse of light can now encode four bits of data instead of just one, because different polarizations can be used to indicate different bit values.
