The sub-Nyquist time-frequency packing (TFP) technique was demonstrated in a superchannel field trial transmission over long-haul distances. The technique allows high spectral efficiency even with low-order modulation formats. The transmission was su

IEEE Optical connections support virtual links in MPLS-over-optical multilayer networks and therefore, errors in the optical layer impact on the quality of the services deployed on such networks. Monitoring the performance of the physical layer allow

We experimentally demonstrate enhanced spectral efficiency (SE) within flexible multicasting operation in a periodically poled Lithium Niobate (PPLN) waveguide. Replicas of quadrature phase-shift keying (QPSK) and 16 quadrature amplitude modulation c

We propose and demonstrate a programmable and self-adaptive VCSEL-based transponder for short-reach applications that is easily extensible up to access and metro scenarios. The transponder presents a monitoring system that feeds the transponder contr

Tunable all optical wavelength conversion of a 200 Gbit/s super-channel data signal based on the cascaded of sum-frequency generation and different frequency generation in a periodically poled lithium niobate waveguide is demonstrated. This principle

CAPS-3 modulation format is used in 100G system for 5G applications. CAPS-3 is simple to generate, can be direct detected, and is able to defeat any significant amount of chromatic dispersion, without the need of digital signal processing in a distan

Coherent detection is the usual solution to achieve high bit rate transmission over long distance. However, it requires a local oscillator and energy consuming digital signal processing that make it not suitable for cost and energy sensitive intercon
