The authors have derived a receiver model that provides an explicit relationship between
the Q factor and the optical signal-to-noise ratio (OSNR) in optical fiber communication …

The small polarization dependence (< 1 dB) of optical components becomes significant in
optical multistage interconnection networks. The cumulative effect can ultimately limit …

We systematically investigate effects of partially polarized noise in a receiver. We introduce
a relationship between the Q factor and the signal-to-noise ratio (SNR) that accounts for …

We propose a quasi mode scrambler to mitigate exaggerated MDL accumulation specific to
recirculating loop systems. We measured accumulated MDL in a recirculating loop system …

A new rigorous formulation to evaluate the performance of optical receivers with arbitrary
optical filtering and partially polarised noise is proposed. The formulation is based on the …

We report on the effect of the partially polarized amplified spontaneous emission noise on
the Q-factor estimation by using optical signal-to-noise ratio. The result shows that this effect …

Results: Fig. 2 shows the optical spectra of the data after 0, 1, 2, 3 and 4 round trips in the
loop, measured on a spectrum analyser with a 2 nm resolution bandwidth. While the spectral …
