Topological MIMO Optical Signal Processing

Romain Christophe Rémy Fleury, Farzad Zangeneh Nejad

An important advantage of optical signal processing is the possibility of performing various operations in parallel. Among the techniques proposed for parallel optical signal processing, frequency division multiplexing (FDM) is a well-known approach, in wh ...

Mode interference and UV-induced mode conversion in few-mode fibers

Soham Basu

Resonant and non-resonant effects in few-mode fibers have found use in versatile devices. From sensing perspective, extensive research has been done on fringe sensitivity of nonresonant two-mode interference. Resonant mode converter gratings are promising ...

Spatial multiplexing of soliton microcombs

Tobias Kippenberg, Maxim Karpov, Erwan Guillaume Albert Lucas, Arslan Sajid Raja, Romain Dany Bruno Bouchand

Dual-comb interferometry utilizes two optical frequency combs to map the optical field's spectrum to a radio-frequency signal without using moving parts, allowing improved speed and accuracy. However, the method is compounded by the complexity and demandin ...

Microresonator-based solitons for massively parallel coherent optical communications

Tobias Kippenberg, Maxim Karpov, Martin Hubert Peter Pfeiffer, Arne Kordts, Victor Brasch, Miles Henry Anderson

Solitons are waveforms that preserve their shape while propagating, as a result of a balance of dispersion and nonlinearity(1,2). Soliton-based data transmission schemes were investigated in the 1980s and showed promise as a way of overcoming the limitatio ...

A simple all-optical format transparent time and wavelength demultiplexing technique for WDM & Orthogonal-TDM Nyquist channels

Camille Sophie Brès, Mohammad Amin Shoaie, Armand Vedadi-Comte

A novel and simple non-coherent method to demultiplex WDM and orthogonal TDM Nyquist signal is presented. Using intensity modulators and filter, demultiplexing from a 3x8x10 = 240 Gb/s signal down to 10 Gb/s is demonstrated. ...

The Orbital Angular Momentum (OAM) Multiplexing Controversy: OAM as a subset of MIMO

Juan Ramon Mosig, Julien Perruisseau-Carrier, Michele Tamagnone, Santiago Capdevila Cascante, Joana Rita Alves dos Santos Silva

Recently the orbital angular momentum (OAM) multiplexing scheme has been proposed to increase supposedly without limit the channel capacity between a transmitter and a receiver nodes communicating in line of sight. A controversy arose about the far-field e ...

Polarization-multiplexed encoding at nanometer scales

Carlos Alberto Macias Romero

Optical data storage was developed using binary encoding primarily due to signal to noise ratio considerations. We report on a multiplexing method that allows a seven fold storage increase, per storage layer, per side, and propose one that can yield theore ...

Investigation of ultra-thin waveguide arrays on a Bloch surface wave platform

Hans Peter Herzig, Libo Yu, Elsie Barakat

Ultra-thin polymer optical waveguide couplers for integrated optics based on Bloch surface waves (BSWs) are presented. Desirable BSW guiding properties, such as low loss and long propagation distance, are observed. The waveguide thickness is on the order o ...

Pattern-reconfigurable built-in antenna for data multiplexing with a single radio

Julien Perruisseau-Carrier, Mohsen Yousefbeiki

Beam-space multiplexing has been demonstrated as a promising approach for transmitting multiple signals while using a single RF chain. This paper presents a novel beam-space antenna design that is very compact and integrated into a hypothetical portable pl ...
