Plasmonic Demultiplexer With Tunable Output Power Ratio Based on Metal-Dielectric-Metal Structure and E7 Liquid Crystal Arrays

open access: yesIEEE Photonics Journal, 2020
A novel tunable plasmonic demultiplexer is proposed and numerically investigated by finite element method (FEM). It consists of two half-nanodisk cavities and two sets of E7 liquid crystal arrays which are side-coupled to three metal-dielectric-metal ...

Noise in Passively Mode-Locked Lasers [PDF]

open access: yes, 1998
For the first time, phase fluctuations in the spectral intensity of the pulse train generated by passively mode-locked semiconductor lasers have been measured. The results reveal diffusion-like fluctuations of this phase.

A Three Demultiplexer C-Band Using Angled Multimode Interference in GaN–SiO2 Slot Waveguide Structures

open access: yesNanomaterials, 2020
One of the most common techniques for increasing data bitrate using the telecommunication system is to use dense wavelength division multiplexing (DWDM). However, the implementation of DWDM with more channels requires additional waveguide coupler devices

An Eight-Channel C-Band Demux Based on Multicore Photonic Crystal Fiber

open access: yesNanomaterials, 2018
A novel eight-channel demux device based on multicore photonic crystal fiber (PCF) structures that operate in the C-band range (1530–1565 nm) has been demonstrated. The PCF demux design is based on replacing some air-hole areas with lithium niobate

Plasmonic Filter and Demultiplexer Based on Square Ring Resonator

open access: yesApplied Sciences, 2018
A ring resonator is a basic component of traditional photonic integrated circuits (PIC), which has been, however, found difficult to be applied efficiently in high-compact plasmonic metal-insulator-metal (MIM) systems.
