Modified Unequally Spaced Channels Wavelength Division Multiplexing System

open access: yesمجلة علوم ذي قار, 2019
The channels contributed in creating new pulse during the four-wave mixing (FWM) process are a subject of two features: the first is the fact that all channels are not working with probability %100 , but with p probability.

Angled multimode interferometer for bidirectional wavelength division (de)multiplexing [PDF]

open access: yesRoyal Society Open Science, 2015
We have demonstrated a bidirectional wavelength division (de)multiplexer (WDM) on the silicon-on-insulator platform using two 4-channel angled multimode interferometers (AMMIs) sharing the same multimode interference waveguide.

Compact polymeric wavelength division multiplexer

open access: yesElectronics Letters, 1999
A compact polymeric wavelength division multiplexer based on a slab waveguide and a reflective transmission grating is presented for application within the low cost data-communications market. The device channel spacing is 800 GHz (6.4 nm), measures only 4/spl times/4 mm in size, displays a polarisation-dependent wavelength shift of 0.1 nm and ...

Multi‐Pathway Upconversion Emission in Symmetry‐Broken Nanocavities: Broadband Multiresonant Enhancement and Anti‐Correlated Interfacial Sensitivity

open access: yesAdvanced Functional Materials, EarlyView.
Symmetry‐broken plasmonic nanoantenna arrays achieve broadband multiresonant enhancement of second harmonic generation (SHG), third harmonic generation (THG), and upconversion photoluminescence (UCPL), under femtosecond laser excitation across the near‐infrared range (1000–1600 nm).

Simultaneous Wavelength- and Mode-Division (De)multiplexing for High-Capacity On-Chip Data Transmission Link

open access: yesIEEE Photonics Journal, 2016
We present designs of wavelength-division-multiplexing (WDM) and mode-division-multiplexing (MDM) optical links using mode de/multiplexers (DE/MUXs) based on multimode interference (MMI) couplers with a tilt joint as a phase shifter.
