Analysis, Optimization, and Modeling of Analog Multi-Tone Serial Data Transceivers

Yusuf Leblebici, Gain Kim, Kiarash Gharibdoust

This paper presents a versatile and fast time-domain architectural modeling framework for high-speed serial data transceivers (TRX) that can employ various analog modulation schemes. We highlight a modeling of TRXs employing an analog multi-tone signaling, ...

Fano-resonance-assisted metasurface for color routing

Olivier Martin, Chen Yan, Kuang-Yu Yang

Controlling the phase of an electromagnetic field using plasmonic nanostructures provides a versatile way to manipulate light at the nanoscale. Broadband phase modulation has been demonstrated using inhomogeneous metasurfaces with different geometries; how ...

Phase analysis of amplitude binary mask structures

Hans Peter Herzig, Toralf Scharf, Krishnaparvathy Puthankovilakam

Shaping of light behind masks using different techniques is the milestone of the printing industry. The aerial image distribution or the intensity distribution at the printing distances defines the resolution of the structure after printing. Contrast and p ...

Harmonization of chaos into a soliton in Kerr frequency combs

Tobias Kippenberg

Dissipative Kerr solitons have paved the way to broadband and fully coherent optical frequency combs in microresonators. Here, we demonstrate numerically that slow frequency tuning of the pump laser in conjunction with phase or amplitude modulation corresp ...

Broadband Uniform Wavelength Conversion and Time Compression of WDM Channels

Camille Sophie Brès, Mohammad Amin Shoaie

A scheme based on 2-pump OPA is proposed for uniform wavelength conversion and optimized compression. We show 4.7-fold compression over 32 nm range resulting in Gaussian pulses from sinusoidal modulation and enabling simultaneous compression of WDM channel ...

ECMA-407: A New 3D audio codec implementation up to NHK 22.2

Marco Mattavelli, Claudio Paolo Alberti, Junaid Jameel Ahmad

ECMA-407, the first 3D audio standard worldwide, introduces a new concept of static models to lower bitrate coding, which may be equally applied with channels, channels and objects and Higher Order Ambisonics (HOA). Static models may either operate in time ...

Coherent terabit communications with microresonator Kerr frequency combs

Tobias Kippenberg, Victor Brasch, Tobias Herr, Jingshi Li

Optical frequency combs have the potential to revolutionize terabit communications(1). The generation of Kerr combs in nonlinear microresonators(2) is particularly promising(3), enabling line spacings of tens of gigahertz. However, such combs may exhibit s ...

Full-duplex Communication and Remote Powering Implementation of an Electronic Knee Implant

Catherine Dehollain, Oguz Atasoy

Full-duplex communication is realized by using ASK modulation for downlink (the channel from controller to the implant) and by using FSK modulation for uplink (from implant to the controller). The ASK modulation is done at the remote powering frequency and ...

Effect of Digitally Modulated Signals on Multipactor Breakdown

Juan Ramon Mosig, Michael Mattes, Apostolos Sounas

This paper studies the effect of digitally modulated signals on the evolution of the multipaction phenomenon. Multipactor is numerically analyzed in a parallel plates waveguide for a variety of common digital modulation techniques. Breakdown power threshol ...
