Linear multimode optical systems have enabled clean experimental observations and the
applications of numerous phenomena that continually extend the boundaries of wave …

Optical communication technology has been advancing rapidly for several decades,
supporting our increasingly information-driven society and economy. Much of this progress …

Space-division multiplexing (SDM) uses multiplicity of space channels to increase capacity
for optical communication. It is applicable for optical communication in both free space and …

Significant effort in optical-fibre research has been put in recent years into realizing mode-
division multiplexing (MDM) in conjunction with wavelength-division multiplexing (WDM) to …

Mode division multiplexing (MDM)–using a multimode optical fiber's N spatial modes as data
channels to transmit N independent data streams–has received interest as it can potentially …

Structured light refers to the ability to tailor optical patterns in all its degrees of freedom, from
conventional 2D transverse patterns to exotic forms of 3D, 4D, and even higher-dimensional …

Current optical communication systems rely almost exclusively on multimode fibres for short-
and medium-haul transmissions, and are now expanding into the long-haul arena. Ultra …

A compact two-mode (de) multiplexer (TM-MUX) based on Si nanowire for mode-division
multiplexing is designed. The TM-MUX is composed of two multimode interference (MMI) …

We demonstrate the fabrication of long-period fiber gratings (LPFGs) written in the two-mode
fiber (TMF) by CO_2 laser. Both uniform and tilted LPFGs were fabricated to provide the light …

Recent developments in spatially multiplexed optical communication systems demand a
deeper understanding of mode coupling effects in fibers. Spatial multiplexing is being …
