Abstract The development of memory devices with functions that simultaneously process and store data is required for efficient computation. To achieve this, artificial synaptic devices have been proposed because they can construct hybrid networks wit

Mode division multiplexing (MDM) has attracted great attention in recent years to increase the network capacity. To apply MDM in data center applications, a low-cost and low power consumption system is desired. In this letter, we utilize 850-nm singl

We demonstrate the passive Q-switching operation of an erbium-doped fiber laser using a few-layer WS2-based saturable absorber with evanescent field interaction. WS2 flakes have been synthesized via a liquid-phase exfoliation method, and an optical f

We demonstrate a highly efficient, broadband fiber-optic intermodal converter. The technique relies on a long period grating mechanically induced in a two-mode fiber. A compact, portable apparatus was designed and fabricated, where period-variable me

We report 25Gb/s mode division multiplexed single-mode VCSEL transmission over a 1-km standard single-mode fiber, which is two-mode at 850 nm with error free performance using fiber-based mode selective multiplexers.

We show all-fiber-based selective mode multiplexers and demultiplexers for weakly-coupled mode-division multiplexed systems. We fabricate a set of six-mode multiplexer and demultiplexer based on fiber mode selective couplers, and experimentally evalu

We present a compact fiber-optic pressure sensor based on a long period fiber grating with the short length of ~1.8 cm (33 grating periods). The grating is induced in a two-mode fiber as a form of periodic micro-bends by an externally tunable inter-m
