Wavelength Division Multiplexing (WDM) [PDF]

, 2018
Postupak valnog multipleksiranja značajno povećava kapacitet optičkog vlakna. Kod svjetlovodnih prijenosnih sustava razlikuju se CWDM i DWDM izvedba, a svaka izvedba zahtjeva određene komponente za ostvarenje prijenosa signala.

Multiplexing Two Types of High‐Order Topological Corner States in Kagome Lattice Photonic Crystals

Nanophotonics, Volume 15, Issue 8, 24 April 2026.
Higher‐order topological corner states in kagome photonic crystals exhibit a direction‐wavelength locking mechanism: two corner states with distinct resonant frequencies couple to different output channels. Harnessing this effect, a 1 × 2 wavelength demultiplexer achieves low‐crosstalk signal separation, demonstrating the potential of topological ...

Diffractive Optical Neural Networks: Pathways Toward Intelligent and Scalable Photonic Computing

Nanophotonics, Volume 15, Issue 8, 24 April 2026.
Diffractive optical neural networks (DONNs) are emerging as a transformative paradigm for photonic computing, offering massive parallelism, ultrafast inference, and passive low‐power operation. This review traces the evolution of DONNs from free‐space to on‐chip implementations, highlights advances in reconfigurability and multidimensional modulation ...

Fundamental Building Blocks for Scalable Photonic Programmable Processors

Nanophotonics, Volume 15, Issue 8, 24 April 2026.
Silicon photonic programmable processors are advanced through the optimisation and experimental validation of key building blocks, including splitters, phase shifters and crossings. In this work, their scalability is experimentally demonstrated at the wafer scale, and their circuit‐level impact is showcased in a high‐speed 4 × 4 optical switch ...

Non‐Volatile Phase Modulation with Ultralow Energy Consumption Enabled by 2D Ferroelectric/TMD Heterostructures

Advanced Science, Volume 13, Issue 13, 3 March 2026.
We demonstrate a hybrid WS2/CuInP2S6/graphene heterostructure integrated on a silicon nitride microring resonator for non‐volatile optical phase modulation with ultra‐low energy consumption and low insertion loss. While CIPS alone does not provide efficient optical index modulation, the engineered proposed device structure converts ferroelctric domain ...
