Here, we demonstrate a compact photonic crystal wavelength demultiplexing device based on a diffraction compensation scheme with two orders of magnitude performance improvement over the conventional superprism structures reported to date. We show that the main problems of the conventional superprism-based wavelength demultiplexing devices can be overcome by combining the superprism effect with ...

Wavelength Division Multiplexing (WDM) plays an important role in optical interconnection. In this paper, a 16-channel WDM device is designed on Silicon-On-Insulator (SOI) substrate by using sub-wavelength grating (SWG) structure, which can cover O-band and C-band at the same time, output channel reversely coupled from main waveguide to realize wavelength demultiplexing. The simulation results ...

This paper presents the design and implementation of an Optical 4:1 Multiplexer using Sagnac Switches as Terahertz Asymmetric Demultiplexers (TOADs). multiplexers play a crucial role in modern communication systems by combining multiple signals onto single optical channel. The proposed multiplexer architecture leverages benefits Switches, such low insertion loss, high extinction ratio, crosstal...

We use mode multiplexing and demultiplexing in apodized aperiodically poled lithium niobate waveguides to enable characterization of picosecond optical pulses in a collinear but background-free way using autocorrelation and second-harmonic frequency-resolved optical gating.

We demonstrate simultaneous demultiplexing, data regeneration and clock recovery at 10Gbits/s, using a single semiconductor optical amplifier-based nonlinear-optical loop mirror in a phase-locked loop configuration.

Herein, a numerical analysis of 1 × 2 demultiplexer based on silica-titania integrated photonics platform is conducted via the finite element method.
