Monolithically integrated reconfigurable add-drop multiplexer for mode-division-multiplexing systems
Optics Letters, 2016An integrated reconfigurable optical add-drop multiplexer (ROADM) for mode-division-multiplexing systems is proposed and demonstrated for the first time, to the best of our knowledge. The present ROADM with four mode-channels is composed of a four-channel mode demultiplexer, four identical 2×2 thermo-optic Mach-Zehnder switches (MZSs), and a four ...

Compact mode-division multiplexing with folded metasurfaces
Metamaterials, Metadevices, and Metasystems 2020, 2020To meet the demand for ever-increasing data transfer rates in fiber optic communications, there is great interest in space-division multiplexing of light. Mode-division multiplexing, a subset of space-division multiplexing, increases the channel capacity of a system by spatial conversion and coupling of optical signals into the orthogonal modes of a ...

Integrated mode converter for mode division multiplexing
SPIE Proceedings, 2016The ever growing demands of bandwidth in optical communication systems are making traditional Wavelength Division Multiplexing (WDM) based systems to reach its limit. In order to cope with future bandwidth demand is necessary to use new levels of orthogonality, such as the waveguide mode or the polarization state.

Mode-Division Multiplexing at Visible Wavelengths
CLEO 2024We demonstrate mode-division multiplexing at visible wavelengths (473 nm) for the first time using adiabatic mode couplers. We measure less than -15 dB and -20 dB crosstalk for TE2 and TE3 higher-order mode couplers, respectively.

Few-mode fibers for mode-division multiplexing
2013 IEEE Photonics Society Summer Topical Meeting Series, 2013The design of few-mode fibers will be discussed from the point of view of key attributes and fundamental limitations. We will consider the maximum number of modes that might be supported in a practical fiber.

MIMO DSP Complexity in Mode-Division Multiplexing
Optical Fiber Communication Conference, 2015We review group delay management techniques and multi-input multi-output (MIMO) digital signal processing (DSP) architectures for mode-division multiplexing systems. We demonstrate long-period fiber grating devices for introduction of strong mode coupling to obtain fast and low complexity MIMO DSP.
