同調光纖通信技術已經受到世界各方的強烈關注，此種通訊技術
可以實現高頻譜效率的傳輸系統。
我們描述操作原理和根據結合光學鎖相注入半導體雷射本機振盪器
的光學鎖相技術的零差同調光接收機實驗性評估。
藉由鎖定到一個低功率為調變的連續光波導頻載體對於數據信號正
交極化, 解調二進制相移鍵控訊號數據可以被達成,
並在相同的條件下與幅移鍵控訊號數據比較的光訊號雜訊比必須減
少3dB。

The coherent optical fiber communication technology is attracting
significant attentions in the world, because it can realize the spectrally efficient
transmission system.
We describe the operating principle, and experimental evaluation of a homodyne
coherent optical receiver based on an optical phase-locking scheme that combines
optical injection locking of the semiconductor laser local oscillator (LO).
By locking to a low-power CW pilot carrier in the polarization orthogonal to the
data signal, demodulation of binary phase-shift-keyed (BPSK) data has been achieved,
with the required SNR reduced by 3 dB compared to demodulation of ASK data under
the same conditions.
