Optical Interconnects using Single-Mode and Multi-Mode VCSEL and Multi-Mode Fiber

Optical Fiber Communication Conference (OFC) 2020, 2020
Single mode (SM) VCSELs, produced in industrial 4” technology, are suitable for 100Gb/s PAM2 and >160Gb/s PAM4 data transmission. >107Gb/s transmission over 1km of multimode (MM) fiber at 850nm and 910nm is realized.

Object recognition through a multi-mode fiber

Optical Review, 2017
We present a method of recognizing an object through a multi-mode fiber. A number of speckle patterns transmitted through a multi-mode fiber are provided to a classifier based on machine learning. We experimentally demonstrated binary classification of face and non-face targets based on the method.

3.56 peta-bit/s C+L band transmission over a 55-mode multi-mode fiber

European Conference on Optical Communication, 2023
We demonstrate transmission of 383 WDMx55 SDMx24.5 GBd 16-QAM signals spanning C-and L-bands over 12.5 km 55 mode fiber. The resulting data rate of 3.56 Pb/s more than doubles the previous record data rate in optical fibers with standard cladding ...

Analyzing spectral properties and sensing performance of multi-single-multi mode fiber combination

Physica Scripta, 2022
Here, we have executed a comprehensive investigation on the impact of the single-mode fiber (SMF) lengths on the sensing performance of multi-single-multi mode (MSM) fiber segment combination under different external parameters including temperature ...

Orbital angular momentum communications based on standard multi-mode fiber (invited paper)

APL Photonics, 2021
Orbital angular momentum (OAM) modes, having unique properties of a helical phase structure and doughnut intensity profile, have been widely studied in fiber-optic communications, in terms of OAM modulation and OAM multiplexing.

Multi-mode fiber soliton laser

Advanced Solid State Lasers, 2001
A multi-mode passively mode-locked soliton fiber laser producing diffraction limited femtosecond pulses is described. The pulses are near bandwidth-limited with a pulse width of 360 fs. The pulse peak powers are 6 kW and the pulse energies can be as high as 4.5 nJ. Frequency-doubling in periodically poled LiNbO3 produces an average power of 75 mW and a
