Homodyne reception
Webhomodyne system with a strong carrier “reference” transmitted in a separate optical line. The modulated signal arm was constructed to have EOM-A followed by an optical attenuator; Bob introduces his base choices in the reference arm at the reception, the setup is shown in Fig. 2.
