A tunable interferometrically stable three-section higher order PMD emulator
01 February 2003
We have developed a technique for emulating higher order polarization mode dispersion (PMD) that utilizes a three-section interferometrically stable configuration. Using this approach, we are able to study the impact of higher order PMD on 10-Gb/s nonreturn-to-zero and carrier-suppressed return-to-zero signals when first-order PMD is zero, which is a typical condition that occurs in one-stage optical PMD compensators.
