We report on the direct fabrication of type I and type II waveguides in z-cut lithium tantalate crystal by varying the parameters of femtosecond laser. The waveguiding properties and reflectance spectrum of the fabricated waveguides were also characterized in this work.

We demonstrate that SPM-enabled spectral selection generates low noise high-energy wavelength tunable femtosecond pulses that exhibit sub-fs relative timing jitter and therefore are tightly synchronized to the source laser pulse.

We demonstrate electrical packaging of a silicon-organic hybrid (SOH) modulator. Gold traces on an AμO3 substrate define the electrical connections to an IQ-modulator having a π-voltage of 1.5 V. Signal generation up to 128 Gbit/s is demonstrated.

We present ultra-smooth silicon nitride waveguides fabricated by the photonic Damascene process extended with a novel reflow step. This leads to record Q-factors for tightly confining waveguides with anomalous dispersion.

We investigate microring resonator (MRRs)-based optical spectral reshaping for directly-modulated 4-PAM signals. The phase-filtering of MRR, and consequent dispersion added to the signal, yields 120% reach increase compared to the 95% of amplitude-only filtering.
