Analog Programmable-Photonic Computation
Andrés Macho-Ortiz, Daniel Pérez-López, José Azaña +1
Digital electronics is a technological cornerstone in our modern society which has covered the increasing demand in computing power during the last decades thanks to a periodic dou…
Microwave Hilbert Transformer and its Applications in Real-time Analog Processing (RAP)
Xiaoyi Wang, Zoé-Lise Deck-Léger, Lianfeng Zou +2
A microwave Hilbert transformer is introduced as a new component for Real-time Analog Processing (RAP). In contrast to its optical counterpart, that resort to optical fiber grating…
Demonstration of input-to-output gain and temporal noise mitigation in a Talbot amplifier
Reza Maram, Mohamed Seghilani, Jinwoo Jeon +4
We experimentally demonstrate intensity amplification of repetitive picosecond optical pulses with an input-to-output gain up to 5.5 dB using a passive Talbot amplifier. Through th…
Channel Multiplexing in Wireless Terahertz Communications Using Orbital Angular Momentum States
Kathirvel Nallappan, Hichem Guerboukha, Mohamed Seghilani +3
We present design and experimental validation of the system for the generation of the Orbital Angular Momentum (OAM) states using 3D-printed low-loss metamaterial phase plates for…
Parametric gain and wavelength conversion via third order nonlinear optics a CMOS compatible waveguide
A. Pasquazi, M. Peccianti, M. Lamont +4
We demonstrate sub-picosecond wavelength conversion in the C-band via four wave mixing in a 45cm long high index doped silica spiral waveguide. We achieve an on/off conversion effi…
First and second order all-optical integrating functions in a photonic integrated circuit
Marcello Ferrera, Yongwoo Park, Luca Razzari +5
We demonstrate all-optical temporal integration of arbitrary optical waveforms with temporal features as short as ~1.9ps. By using a four-port micro-ring resonator based on CMOS co…
Measurement of ultrashort optical pulses via time lens imaging in CMOS compatible waveguides
Alessia Pasquazi, Yongwoo Park, Sai T. Chu +5
We demonstrate temporal measurements of subpicosecond optical pulses via time-to-frequency conversion in a 45cm long CMOS compatible high index glass spiral waveguide. The measurem…
Passive, Noiseless, Intensity Amplification of Repetitive Signals
R. Maram, J. van Howe, M. Li +1
Amplification of signal intensity is essential for initiating physical processes, diagnostics, sensing, communications, and scientific measurement. During traditional amplification…
Novel extraction algorithm for amplitude and phase measurement of ultrashort optical pulses via spectral phase interferometry
Alessia Pasquazi, Marco Peccianti, Jose Azana +2
We present a novel extraction algorithm for spectral phase interferometry for direct field reconstruction (SPIDER) for the so-called X-SPIDER configuration. Our approach largely ex…
Phase-sensitive optical pulse characterization on a chip via Spectral Phase Interferometry for Direct Electric-Field Reconstruction (SPIDER)
Alessia Pasquazi, Marco Peccianti, Yongwoo Park +5
The recent introduction of coherent optical communications has created a compelling need for ultra-fast phase-sensitive measurement techniques operating at milliwatt peak power lev…
