Mode demultiplexing hybrids for mode-division multiplexing coherent receivers

Photonics Research, 2019
We propose a mode demultiplexing hybrid (MDH) that integrates mode demultiplexing, local oscillator power splitting, and optical 90-deg mixing using multi-plane light conversion (MPLC).

Integrated Switch for Mode-Division Multiplexing (MDM) and Wavelength-Division Multiplexing (WDM)

CLEO: 2015, 2015
We demonstrate the first integrated switch for mode-division multiplexing (MDM) and wavelength-division multiplexing (WDM). We show on-chip routing of four 10 Gb/s channels with

Silicon-based hybrid demultiplexer for wavelength- and mode-division multiplexing.

Optics Letters, 2018
A silicon-based hybrid demultiplexer for wavelength-division multiplexing (WDM) and mode-division multiplexing (MDM) is proposed and demonstrated by integrating an M-channel-mode demultiplexer and N-channel WDM filters based on microring resonators (MRRs)

Bidirectional mode-division multiplexers with antireflection gratings

Applied Optics, 2018
A bidirectional mode-division multiplexer (BMDM) with antireflection gratings is designed, and its performance in terms of S-parameters is presented. A BMDM can (de)multiplex three modes with only two waveguides and a Bragg grating. The impact of return losses on the performance of BMDMs is studied and antireflection gratings are designed to reduce ...

Mode Division Multiplexing of Modes With the Same Azimuthal Index

IEEE Photonics Technology Letters, 2012
The design of an SLM-based mode demultiplexer is discussed and mode division multiplexing is performed using the LP0,1 and LP0,2 modes, representing the first demonstration to propagate channels on modes with the same azimuthal index. Mode multiplexed transmission over 2 km of 50-μm OM2 fiber demonstrates a modal selectivity of 16 dB and an OSNR ...

Few-mode fiber technology for mode division multiplexing

Optical Fiber Technology, 2017
Abstract We review recent progress on few-mode fiber (FMF) technologies for mode-division multiplexing (MDM) transmission. First, we introduce fibers for use without and with multiple-input multiple-output (MIMO) digital signal processing (DSP) to compensate for modal crosstalk, and briefly report recent work on FMF for use without/with a MIMO DSP ...

Low loss mode multiplexer de-multiplexer for mode division multiplexing over two mode fiber

2015 Workshop on Recent Advances in Photonics (WRAP), 2015
Mode Division Multiplexing (MDM) over Few Mode Fiber (FMF) enhances the capacity of an optical fiber system by providing additional degrees of freedom in the form of modes which are selectively excited at the transmitter and selectively detected at the receiver. The key to capitalize on such a system is implementation of low loss mode multiplexer (mux)

Mode coupling effects in mode-division-multiplexed systems

2012 IEEE Photonics Society Summer Topical Meeting Series, 2012
Mode coupling is a key to overcoming major challenges in mode-division-multiplexed (MDM) long-haul systems using coherent detection. Strong mode coupling reduces the modal group delay spread, minimizing the complexity of digital multi-input multi-output (MIMO) signal processing.

Switching and Multiplexing Technologies for Mode-Division Multiplexed Networks

Optical Fiber Communication Conference, 2017
• Mode-multiplexing over multimode fibers has the potential to scale WDM networks by a factor of 10 or more • Multimode components like wavelength selective switches and optical amplifiers can scale to large number of modes • Wavelength selective switches, which are the basic building block for WDM network can be extended to support multimode fibers ...
