Ultralow‐Dispersion Silicon THz Photonic Crystal Interconnects for Multichannel Datalinks

Advanced Materials, EarlyView.
An all‐silicon terahertz photonic crystal waveguide interconnect enables 452 Gbps aggregate data transfer through seven complex‐modulated channels. By revealing the impact of ultralow dispersion on link performance and achieving a record interconnect figure of merit, the work advances centimeter‐scale THz on‐chip communication for future data‐centre ...

Polarization-Independent Mode-Evolution-Based Coupler for the Silicon-on-Insulator Platform

IEEE Photonics Journal, 2018
We demonstrate a polarization-independent mode-evolution-based coupler for the silicon-on-insulator platform. The measured coupler has negligible insertion loss over a bandwidth of about 100 nm, i.e., from 1500 to 1600 nm.

Far‐Infrared Hyperbolic Phonon–Polaritons in Zirconium Disulfide

Advanced Materials, EarlyView.
An unpatterned ZrS2${\rm ZrS}_2$ flake, coupled to far‐field infrared light by metal nanoribbons, reveals hyperbolic phonon polaritons with multiple higher‐order branches and effective refractive indices up to 223. This resonator‐assisted approach establishes ZrS2${\rm ZrS}_2$ as a compact van der Waals platform for deeply subwavelength far‐infrared ...

Design and Fabrication of Broadband Polymer Mode (De)Multiplexer Using a Direct Inscribing Method

IEEE Photonics Journal, 2018
We demonstrate the design and fabrication of a mode (de)multiplexer based on the tapered mode-selective coupler. The proposed device is directly inscribed in the substrate material by a needle-type liquid micro-dispenser and a three-axis robot stage ...

Coupling terahertz wave into a plasmonic waveguide by using two ribbon waveguides

Results in Physics, 2020
We proposed the design of coupling terahertz wave into a plasmonic waveguide via using two alumina ribbon waveguides. The dispersion relation of fundamental alumina waveguide mode shows that it has intersections with plasmonic modes, resulting in the ...

Reversible Hydration Tuning of Polar Order and Large Nonlinear Optical Response in a 2D van der Waals Crystal, LiInP2S6

Advanced Materials, EarlyView.
Hydration‐induced symmetry breaking transforms layered LiInP2S6${\rm LiInP}_2{\rm S}_6$ from a nonpolar to a chiral‐polar phase, producing a giant enhancement of non‐resonant second‐harmonic generation. The reversible tuning of polar order through molecular intercalation establishes a strategy for dynamically controlling nonlinear optical ...

Magneto-optical non-reciprocal devices in silicon photonics

Science and Technology of Advanced Materials, 2014
Silicon waveguide optical non-reciprocal devices based on the magneto-optical effect are reviewed. The non-reciprocal phase shift caused by the first-order magneto-optical effect is effective in realizing optical non-reciprocal devices in silicon ...

Unveiling α‐MoO3 as a High‐Index, Low‐Loss Anisotropic Material: Bridging the Gap From Mid‐Infrared to Ultraviolet Nanophotonics

Advanced Materials, EarlyView.
α‐MoO3 is established as a high‐index, low‐loss anisotropic platform bridging mid‐infrared polaritonics and ultraviolet‐visible nanophotonics. Spectroscopic ellipsometry and calculations reveal refractive indices exceeding 3.9, with the largest in‐plane birefringence among transparent layered crystals at 425–500 nm, enabling zero‐order UV waveplates ...

Clearing a path for light through non-Hermitian media

Nanophotonics
The performance of all active photonic devices today is greatly limited by loss. Here, we show that one can engineer a low loss path in a metal-clad lossy multi-mode waveguide while simultaneously achieving high-performance active photonic devices.
