We propose and compare add-drop multiplexing schemes for Nyquist OTDM signals based on 1 x2 or 2 x2 Mach-Zehnder modulator. Bright and dark sinc pulse carver simultaneously provided by the modulator fulfil drop, notch and add functions. ...

Optical sinc-shaped Nyquist pulses are produced based on the generation of an ideal frequency comb using cascaded intensity modulators. Nyquist pulses with 9.8-ps temporal width, 82-fs jitter and more than 40 dB SNR are achieved. ...

We experimentally demonstrate for the first time, the efficient input-dependent dual-range frequency shifts of 279.73 GHz and 3.63 THz in a mode-locked fiber laser with an intracavity epsilon-near-zero element. Real-time observation reveals that the presen ...

In the last decade, aluminum nitride (AlN) has proven to be an attractive material for both linear and nonlinear integrated photonics, due to its large transparency window, its low propagation losses and the presence of both second- and third-order nonline ...

We demonstrate seeding-enabled all-optical poling of silicon nitride waveguides as short as 5 mm, and account for quasi-phase-matching (QPM) inside the waveguide between the fundamental mode of pump and higher order second-harmonic modes. ...

System and methods for producing a plurality of Sinc shaped pulses in the time domain include a light source for providing an input light signal having an input frequency, and at least one spectrum shaper for producing the plurality of Sinc shaped pulses f ...

We demonstrate the linear electro-optic effect in a silicon nitride micro-ring in which an effective second order nonlinearity is enabled by optically assisted electrical poling. Charge carriers' separation in the waveguide creates a permanent electric-fie ...

Directly accessing the middle infrared, the molecular functional group spectral region, via supercontinuum generation processes based on turn-key fiber lasers offers the undeniable advantage of simplicity and robustness. Recently, the assessment of the coh ...

Efficient third-order nonlinear optical processes have been successfully integrated on silicon nitride (Si3N4) waveguides. In particular, owing to Si3N4 wide transparency window spanning from the visible to the middle-infrared (mid-IR), efficient mid-IR di ...

A method to produce highly-stable optical sinc-shaped pulses is proposed based on the generation of a rectangular-spectrum frequency comb. Nyquist pulses with

We report wavelength multicasting to three 5Gb/s channels around 1950nm via broadband four-wave-mixing between RZ-OOK modulated pump and O-band signals. The thulium-assisted configuration enables high fidelity copying and output powers of 10’s of mW. ...

We propose a novel scheme of temporal Talbot effect achieving optical pulse train repetition-rate multiplication in a conventional tapped delay line structure. While it is generally used for spectral amplitude filtering, we show that such architecture coul ...

We show how broadband (>30nm) quasi-phase matching in all-optically poled Si3N4 waveguides provides a platform for efficient sum-frequency generation, and for femtosecond pulse processing such as fcEo detection without the need for group velocity engineeri ...

We report broadband continuous-wave frequency conversion from the O-band (1.33 μm) to the short-wave infrared (2.6 μm) in a 50 cm long low-loss Si3N4 waveguide, leveraging polarization selective far-detuned phase matching. ...

Continuous-wave four-wave mixing conversion efficiency-bandwidth trade-off in silicon nitride waveguides is investigated to reach efficient and broadband wavelength conversion. Additionally, parametric gain and efficient cascaded four-wave mixing is observ ...

A Brillouin probing method is proposed to extract the distribution of signal power along phase-sensitive parametric amplifiers. Operation near the zero-dispersion-wavelength shows enhanced sensitivity to dispersion fluctuations, allowing effective extracti ...

Silicon Nitride (S13N4) waveguide platforms have seen significant interest in the recent years, motivated by several advantageous properties such as compatibility with CMOS fabrication standards, low propagation loss, high refractive index and optical nonl ...

A tunable, stable pulse generation technique based on two-pump fiber optic parametric amplification is theoretically analyzed and experimentally demonstrated to generate uniform near-Gaussian pulses over 32 nm. It is shown that pulse shape can also be tune ...

We demonstrate simultaneous detection of acetylene, methane and ethane using milliwatt-level dispersive-wave generated in a Si3N4 waveguide covering 2900 cm-1-3380 cm-1 spectral region. This simple mid-IR absorption spectroscopy scheme achieves hundreds of ...
