Coherent reception becomes an interesting option when data rates in time-division-
multiplexed (TDM) passive optical networks (PONs) grow beyond 50 Gbit/s. Controlling the …

The phase noise characteristics and laser stabilization time of a tunable laser under both
static and fast switching operation is characterized using a dynamic linewidth measurement …

A widely tunable burst mode digital coherent receiver is implemented in a 112 Gb/s DP-
QPSK WDM system. The receiver performance is validated in a 24-channel WDM test-bed …

We experimentally analyze an adaptive polarization-demultiplexing (PolDemux) technique
based on the representation of the state of polarization of the signal in the Stokes space. The …

In this paper, the requirements for next generation passive optical network (NG-PON) and
evolution trends of PON are analyzed. Based on the analysis of the requirements for …
