We consider realistic long-haul optical links, with linear and nonlinear impairments, and
investigate the application of time-frequency packing with low-order constellations as a …

An optical-fiber measurement system includes an optical system that generates light and a
spatial optical switch that is coupled to the optical system that processes the light generated …

In this paper, we review recent developments in the area of terabit/s class monolithically
integrated, transmitter and receiver photonic integrated circuits for the implementation of …

An integrated optical system includes a frequency tunable optical source. A reference path is
coupled to the frequency tunable source. The integrated optical system also includes a …
