RECEIVER FOR LIGHTWAVE TRANSMISSION SYSTEM USING HOMODYNE DETECTION |
摘要 |
<p>A coherent electromagnetic wave transmission system includes an electromagnetic wave transmission medium (30) for propagating two orthogonally polarized coherent electromagnetic signals. When received the two polarized signals are separated into an information component (52) and a reference component (48) that is coherent with the information component. The reference component drives an amplifier (50) for producing an amplified reference component that is coherent with the information component. Mixing the coherent amplified reference component with the information component in a homodyne detector produces a base-band information signal (82).</p> |
