Active modulation of light with large optical bandwidths (∼100 nm [1]) is required in photonic devices, such as modulators for fiber communications [1] and saturable absorbers for ultrafast pulse generation [2,3]. Present modulators use expensive materials, (e.g. LiNbO3 [4], III-V semiconductors [5], and Ge on silicon-on-insulator (SOI) [6]), and are limited by narrowband operation (∼20 nm for quantum-confined...
We demonstrate timing jitter characterization of mode-locked lasers with attosecond-resolution using optical heterodyne techniques. The measured integrated jitter for a free-running mode-locked Er:Yb:glass laser was found below 20 as from 10 kHz to 5 MHz.
A 1 Gbps 105.4 GHz wireless link is demonstrated by directly modulating a photonic integrated dual-laser source. A 50 m link is predicted to be able to achieve error free operation using FEC following optimisation.
We have fabricated and characterized ultrathin NbTiN films with high Titanium (Ti) composition for applications of superconducting nanowire single photon detectors (SNSPD). An alloy with 47 wt. % Ti and 53 wt. % Nb as the target material is employed. NbTiN thin films with thicknesses ranging from 5 nm to 20 nm are grown onto MgO (100), Si (100) and $\hbox{SiO}_{\rm X}\hbox{-Si} $ substrates by DC...
