Abstract:
An orthogonal frequency division multiplexing (OFDM) transmitter is able to communicate simultaneously with a simple direct detection receiver and also with a coherent receiver. The transmitter transmits a polarization multiplexed self-coherent signal by multiplexing a carrier in the polarization state orthogonal to the polarization state of the data signal that is embodied in the sidebands. In accordance with one particular aspect of the disclosure, the direct detection receiver receiving this self-coherent signal utilizes a single polarization analyzer before the photodiode, which simplifies the receiver architecture for direct detection of a polarization multiplexed self-coherent single sideband signal.

Claim (Index 10):
The method of  claim 1 , wherein detecting the polarization components of both the optical carrier frequency and the single sideband comprises detecting the polarization components of both the optical carrier frequency and the single sideband using a balanced receiver having a pair of photodetectors.
