Optical transmitters with unbalanced optical sidebands separated by gaps |
摘要 |
An apparatus comprising a transmitter configured to generate an optical signal comprising a carrier modulated with at least two sidebands modulated with information, wherein the information introduces a separation gap in a frequency domain between the sidebands and the carrier, wherein one of the sidebands is an undesired sideband and another one of the sidebands is a desired sideband with a higher power intensity than the undesired sideband. A method comprising receiving an optical carrier from a light source and modulating the optical carrier with at least two sidebands modulated with information, wherein the information introduces a separation gap in a frequency domain between the sidebands and the optical carrier, wherein one of the sidebands is an undesired sideband and another one of the sidebands is a desired sideband having a higher power intensity than the undesired sideband. |

1. An apparatus comprising:
a transmitter configured to generate an optical signal comprising a carrier modulated with at least two sidebands modulated with information, wherein the information introduces a separation gap in a frequency domain between the sidebands and the carrier, wherein one of the sidebands is an undesired sideband and another one of the sidebands is a desired sideband, wherein the sidebands are unbalanced due to the desired sideband having a higher power intensity than the undesired sideband prior to transmission, wherein the information comprises a sub-carrier modulated (SCM) signal and a direct component (DC), and wherein the separation gap is introduced through a gap between the SCM signal and the DC. |
