PDM-(M) Ask Optical Systems And Methods For Metro Network Applications |
| 摘要 |
An apparatus, e.g. an optical communication system, includes an optical transmitter and an optical receiver. The transmitter includes a laser configured to provide an optical signal amplitude-modulated among M different levels, e.g. in two polarizations. The receiver is configured to demodulate the optical signal to produce a received symbol constellation including a plurality of symbol rings in a complex I-Q space. |

1. An apparatus, comprising:
an optical transmitter including a laser configured to provide an optical signal amplitude-modulated among M different levels; and an optical receiver configured to demodulate the optical signal to produce a received symbol constellation including a plurality of concentric symbol rings in a complex I-Q space. |
