Abstract: A skew compensation apparatus and method. In an optical system that uses optical signals, skew may be generated as the optical signals are processed from an input optical signal to at least two electrical signals representative of the phase-differentiated optical signals. A compensation of the skew is provided by including an optical delay line in the path of the optical signal that does not suffer the skew (e.g., that serves as the time base for the skew measurement). The optical delay line introduces a delay Tskew equal to the delay suffered by the optical signal that is not taken as the time base. The two signals are thereby corrected for skew.

Abstract translation: 偏斜补偿装置及方法。 在使用光信号的光学系统中，当光信号从输入光信号处理成至少两个表示相位微分光信号的电信号时，可能产生偏斜。 通过在不受歪斜的光信号的路径中包括光延迟线（例如，用作歪斜测量的时基）来提供偏斜的补偿。 光延迟线引入的延迟Tskew等于不被视为时基的光信号所遭受的延迟。 因此，两个信号被纠正为偏斜。
