Absolute polar duty cycle division multiplexing over wavelength division multiplexing system [PDF]

Optics Communications, 2009
The performance of absolute polar duty cycle division multiplexing (AP-DCDM) over wavelength division multiplexing (WDM) system is presented based on the simulation results. The AP-DCDM signal has narrower bandwidth than conventional time division multiplexing (TDM) signal, which makes its implementation in WDM system advantageous.

Spatial and Polarization Division Multiplexing Harnessing On‐Chip Optical Beam Forming

Laser & Photonics Reviews, 2023
AbstractOn‐chip spatial and polarization multiplexing has emerged as a powerful strategy to boost the data transmission capacity of integrated optical transceivers. State‐of‐the‐art multiplexers require accurate control of the relative phase or the spatial distribution among different guided optical modes, seriously compromising the optical ...
