WB3.1 - COHERENT CO-PACKAGED OPTICAL INTERFACES FOR NEXT-GENERATION ELECTRICAL SWITCHES
Abstract
Abstract
We propose power-efficient co-packaged interfaces for electrical switches. Using external light sources and coherent detection, they provide multi-Tb/s-per-fiber throughput, while tolerating both losses in integrated photonics and thermal (de)multiplexer shifts exceeding the channel spacing.
WB3.2 - EXPERIMENTAL DEMONSTRATION OF DUAL-POLARISATION NFDM TRANSMISSION WITH B-MODULATION
Abstract
Abstract
Dual-polarisation Nonlinear Frequency Division Multiplexing transmission has been investigated recently due to its potential of doubling the capacity of single polarisation NFDM systems. By employing the concept of b-modulation, we have experimentally demonstrated for a DP-NFDM transmission system with a net data rate of 220 Gbps.

Abstract
Abstract
We present the theory and realization of a spectrally-partitioned 4x4 crossbar switch, with three microring resonators per cross-point having disjoint resonance regions within a free spectral range. This demonstration of the switch includes a driver. We describe an associated energy efficient, non-blocking wavelength assignment algorithm.
WB3.4 - THE KRAMERS-KRONIG RECEIVER
Abstract
Abstract
The Kramers–Kronig (KK) receiver allows the exact reconstruction of a complex-valued optical signal from the detection of its intensity. This presentation reviews the operation principles and various implementations of the KK scheme, highlighting its main advantages and limitations.
