    • A method and apparatus for sampling optical input signal is presented. The apparatus includes a split waveplate for spatially rotating polarization direction of a first portion (for example half, or 50 percent) of the input signal to a first rotated direction and spatially rotating polarization direction of a second portion (for example the other 50 percent) of the input signal to a second rotated direction orthogonal to the first rotated direction. The apparatus further includes a sum frequency generator, for example a PPLN crystal, aligned to the first rotated direction to sample the input signal. The rotation of the two halves of the input signal is achieved using a split half-waveplate.

    • G01J11/00
    • A nonpolarization-dependent method and apparatus for optical sampling of a user optical signal of a known frequency range (e.g., corresponding to 1550 nm wavelength) uses a probe signal in an unsplit form and applies a conversion {e.g., by sum frequency generation (SFG)} operation in a first stage to the probe signal and to a first polarization component of the user optical signal (e.g., ‘s’ component) to produce a first component of an output signal. In a second stage, a second polarization component of the user optical signal (e.g., ‘p’ component) is rotated by 90° to align with the first polarization component and then converted by mixing with the unsplit probe signal to produce a second component of an output signal. The first and second output component signals are both added and measured using a photomultiplier tube (PMT) or an avalanche diode.

    • A sampling apparatus for use in high data rate jitter measurement systems based on offset sampling uses a trigger circuit, along with a time-based variable delay, to align a sampling strobe to drive two samplers. An input data signal is split and fed via separate signal paths into the two samplers. One of the samplers is delayed in sampling the input signal or the input is delayed to one of the samplers, such that the two samples of the input signal are offset in time. The jitter present in the SUT can be calculated using the two samples. In addition, when using two strobe circuits, the jitter inherently present in the strobe circuits can be compensated for by offset sampling a reference clock with each main strobe to determine the phase and cycle number of the reference clock at each strobe time.
    • 用于基于偏移采样的高数据速率抖动测量系统的采样装置使用触发电路以及基于时间的可变延迟来对准采样选通以驱动两个采样器。 输入数据信号被分离并通过分离的信号路径馈送到两个采样器中。 其中一个采样器在对输入信号进行采样时被延迟,或者输入延迟到采样器之一,使得输入信号的两个采样在时间上偏移。 SUT中存在的抖动可以使用两个采样来计算。 此外,当使用两个选通电路时,可以通过对每个主选通脉冲采样参考时钟来补偿选通电路中固有存在的抖动,以确定每个选通时间的参考时钟的相位和周期数。
