    摘要： Consistent with the present disclosure, polarized optical signals having the same wavelength are modulated in response to ERZ drive signals, to thereby yield corresponding RZ optical signals. Each of the polarized RZ optical signals includes a plurality of RZ transitions wherein the power of the optical signal returns to zero or a minimal power between bits or symbols. The phase or timing of the ERZ drive signals, however, is controlled, so that the RZ transitions in one polarized optical signal remain interleaved with the RZ transitions of the other polarized optical signal. Alternatively, the RZ transitions of the two polarized optical signals may be controlled so that the two are temporally aligned with one another. Thus, the timing of the RZ transitions of one polarized optical signal relative to the other polarized optical signal may be adjusted to optimize system performance.

    摘要翻译： 根据本公开，响应于ERZ驱动信号调制具有相同波长的偏振光信号，从而产生相应的RZ光信号。 每个极化RZ光信号包括多个RZ转变，其中光信号的功率返回零或位或符号之间的最小功率。 然而，ERZ驱动信号的相位或定时被控制，使得一个偏振光信号中的RZ转变保持与另一个偏振光信号的RZ跃迁交错。 或者，可以控制两个偏振光信号的RZ转变，使得两者在时间上彼此对准。 因此，可以调整一个偏振光信号相对于另一个偏振光信号的RZ转变的定时，以优化系统性能。

    摘要： An optical system may include a polarization beam splitter having an input that receives multiple optical signals, a first output and a second output. The first output may provide components of the multiple optical signals having a first polarization. The second output may provide components of the multiple optical signals having a second polarization. The optical system may include a rotator having an input that receives the components to rotate the first polarization such that each of the components has the second polarization, and an output to supply components as rotated components.The optical system may also include an optical circuit including a substrate. The rotator may be separate from the substrate. The optical circuit may include an optical demultiplexer circuit provided on the substrate to receive the rotated components and the components.
