METHOD AND SYSTEM FOR AMPLITUDE MODULATION OF AN OPTICAL SIGNAL |
摘要 |
The invention relates to a method and to a system for amplitude modulation of an optical signal (os) with a binary data signal (ds). To this end, the optical signal (os) is divided up into a first and a second adjustable optical signal (os1, os2). The first optical signal (os1) is supplied to a modulator (MZM) that outputs an optical transmission signal (ts) after amplitude modulation with a binary data signal (ds). A counter-phase second optical signal (gps) is produced from the second adjustable optical signal (os2) and the optical transmission signal (ts) and the counter-phase second optical signal (gps) are combined to a carrier-reduced optical transmission signal (rts). |
