The intra-and inter-data center links face continuously increasing pressure on the
transmission capacity while having to meet strict constraints in cost and power consumption …

Single section quantum dash (QDash) mode locked lasers (MLL) can provide a flat and
broadband optical frequency comb with low energy consumption, operational simplicity and …

The remote delivery of optical reference with highly stable oscillation frequency and carrier
phase can eliminate the need of digital signal processing for the estimation of these …

For space division multiplexing self-homodyne coherent systems, we propose a novel digital
in-service relative time delay (RTD) estimation method without any additional optoelectronic …

In this experimental study, the dynamics of a quantum well semiconductor laser (SL) under
optoelectronic (OE) feedback are investigated. The feedback is configured by splitting the …

The estimation of laser linewidth or phase noise variance is of great significance for the
applications including coherent optical communications, optical fiber sensing, quantum …

Dispersion uncompensated fiber links are widely used due to their nonlinear benefits. In
such links, dispersion requires electronic compensation after down-conversion by the …

In this paper, we discuss a new technique for measuring transceiver noise, skew, and for the
detection of uncompensated transceiver impairments. The method introduces frequency …
