A single 160 Gbaud Nyquist channel transmission based on coherent matched sampling under 4 km lab-emulated free-space turbulence link is demonstrated. Turbulence induced power fluctuation is found to be main reason of performance deterioration.
In this paper, we report developments of electro-optical PCBs (EO-PCB) with embedded polymer waveguide layers. The paper focuses on results for fabricating and characterizing the first multimode demonstrator designed in the PhoxTrot project. Our results shows successful fabrication of complex waveguide structures and integration of optical layer part of hybrid optical / electrical PCBs utilizing production...
Photonic crystal filaments were demonstrated with noncollinear filaments interaction, resulting in elongated filaments and third harmonic generation of more than two orders enhancement as compared with that from a single filament.
By using field-free molecular alignment, we demonstrate the multi-filaments of ultrashort laser pulse with input spatial ellipticity can be suppressed to be a single core, or be controlled to various structures with modulated spectra.
We show that the polarization of surface-plasmon-resonance enhanced optical field can be manipulated to be linear by using a polarization-gating scheme, which benefits the ultrafast electron acceleration and efficient XUV frequency comb generation.
Proposed is a novel structure of a cascadable photonic serial-to-parallel converter (SPC) based on the cross-phase modulation effect in a semiconductor optical amplifier for simultaneous multiple-channel optical time division multiplexed demultiplexing. The proposed SPC features cascadability, compact structure, high-speed operation, and simultaneous two-channel operation. Error-free 20 Gbit/s simultaneous...
Two-dimensional multicolored arrays of quadratic spatial solitons and up-converted parametric amplifications are observed through cascaded non-collinear quadratic processes in quadratic media, which can be switched by phase-insensitive weak beam control with second harmonic seeding pulses.
Femtosecond upconversion was realized by seeded amplification of colored conical emission via spatiotemporal modulational instabilities in a thick quadratical nonlinear crystal, which could be widely tuned by adjusting the seed angle or delay
