TL;DR: In this article, a tunable four-wave mixing (FWM) wavelength conversion based on SOA-based fiber ring laser is analyzed theoretically and experimentally, and the authors show that the exploitation of erbium-doped fiber amplifier (EDFA) is helpful for tuning range widening and input dynamic range increasing.

TL;DR: In this article , a novel silicon-based integrated multidimensional terahertz (de)multiplexer for high-capacity communication is proposed and demonstrated based on ring resonators and polarization beam splitter-rotators, which simultaneously enable the manipulation of THz polarization and frequency.

TL;DR: In this paper, a double-layer graphene electro-absorption photonic crystal waveguide modulator was demonstrated with a modulation depth of 0.5 dB/μm with a bandwidth of 13.6 GHz in simulations.

TL;DR: In this article, the authors proposed an orbital angular momentum (OAM) divider based on coordinate transformation, which can convert the OAM light into multiple diffracted light and realize equal N-dividing of OAM.

TL;DR: In this article , an energy-efficient, fast-response, and low-loss TO phase shifter was proposed by introducing hydrogen-doped indium oxide (IHO) films as microheater, and the optimized electron concentration with enhanced mobility endows the IHO high conductivity as well as high near-infrared (NIR) transparency, which allow it to directly contact the silicon waveguide without any insulating layer for efficient tuning and fast response.
