Interferometric devices have drawn a great interest in all-optical signal processing for their
high-speed photonic activity. Quantum-dot semiconductor optical amplifier (QD-SOA)-based …

With high-bandwidth and on-demand applications continuing to emerge, next-generation
core optical networks will likely require significant improvements in reconfigurability and …

Silicon-based photonic crystal nanocavities with different lattice pitches were monolithically
integrated with a total length of only 200 μm, and were operated as a multi-channel all …

An enhanced version of the conventional differential scheme, employed to decouple the
switching speed of an active Mach-Zehnder interferometer from the recovery time of its main …

An all-optical packet switching using bistable photonic crystal nanocavity memories was
demonstrated for the first time. Nanocavity-waveguide coupling systems were configured for …

This paper presents recent progress toward the realization of ultrahigh-speed coherent
optical transmission with a single-channel bit rate of more than 1 Tbit/s using ultrashort pulse …

In this paper, we review emerging technologies to build up Tb/s per channel transmission
capacity. The different approaches, mainly based on various implementations of orthogonal …

We present an ultrahigh-speed optical demultiplexing concept based on optical blue-shift
filtering in a quantum-dot semiconductor optical amplifier (QD-SOA). Using a simple …

We present a wavelength-tunable ultrafast optical switch using a nonlinear optical loop
mirror (NOLM), which has a low walk-off characteristic between the signal pulse and the …

Optical data comparator is the part and parcel of arithmetic and logical unit of any optical
data processor and it is working as a building block in a larger optical circuit, as an optical …
