Clock Recovery Challenges in DSP-Based Coherent Single-Mode and Multi-Mode Optical Systems

open access: yesFuture Internet, 2018
We present an analysis of clock recovery algorithms in both polarization division multiplexing systems and mode division multiplexing systems. The impact of inter-polarization time skew and polarization mode dispersion in single-mode fibers, as well as ...

Silicon Chip-to-Chip Mode-Division Multiplexing [PDF]

open access: yesOptical Fiber Communication Conference, 2018
A chip-to-chip mode-division multiplexing connection is demonstrated using a pair of multiplexers/demultiplexers fabricated on the silicon-on-insulator platform. Successful mode multiplexing and demultiplexing is experimentally demonstrated, using the LP 01 , LP 11a and LP 11b modes.

Three-dimensional mode-division multiplexing system

open access: yesOptics Express, 2023
Blindly increasing the channels of the mode (de)multiplexer on the single-layer chip can cause the device structure to be too complex to optimize. The three-dimensional (3D) mode division multiplexing (MDM) technology is a potential solution to extend the data capacity of the photonic integrated circuit by assembling the simple devices in the 3D space.

High-Dimensional Modulation for Mode-Division Multiplexing [PDF]

open access: yesOptical Fiber Communication Conference, 2014
We explore high-dimensional modulation for mode-division multiplexed optical fiber communication systems, focusing on optimized 24-D modulation formats in six-mode fiber transmission. Compared with conventional formats, our simulations demonstrate up to 8.7 dB span loss budget improvement for 6 b/s/Hz intra-channel spectral efficiency.
