Variable Line-Rate Optical Transmitter by Modulation Format Hopping Using Electrical-Optical-Electrical EOE Generated QAM Signal |
摘要 |
The present method is for generating a 4-level optical signal and it includes providing a continuous wave CW optical source; modulating the CW optical source with a first intensity modulator driven by a binary electrical signal a n Gbits/s to generate an optical signal; employing a second intensity modulator as a pulse carving modulator that is driven by an RF signal at n GHz thereby generating a 4 level optical signal for subsequent detection by a receiver. |
