Design of Few-Mode Fibers for Mode-Division Multiplexing Transmission
IEEE Photonics Journal, 2013 We investigate the fiber parameters that meet the design conditions for low bending loss and an effectively few-mode operation on few-mode fibers with a step-index profile and a W-shaped refractive index profile for mode-division multiplexing ...

Three-dimensional mode-division multiplexing system
Optics 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.

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

Tumor B‐cell infiltration in platinum‐treated advanced muscle‐invasive urothelial carcinoma
Molecular Oncology, EarlyView.Bladder tumors with higher pretreatment memory B‐cell infiltration were linked to longer survival after cisplatin chemotherapy, but not carboplatin. These tumors also showed more organized immune structures (tertiary lymphoid structures) and a shared pro‐inflammatory B‐cell‐rich community, suggesting that memory B cells may help identify patients most ...
