Stimulated Forward Brillouin Scattering in Subwavelength Grating Silicon Membranes

Laser &Photonics Reviews, EarlyView.
This work proposes a novel strategy to achieve large Brillouin scattering with independent control of the optical and mechanical modes using subwavelength silicon membranes. We experimentally demonstrate remarkably high Brillouin gain, resulting in an on/off Stokes gain of 3 dB and anti‐Stokes loss of 4 dB in a 6 mm‐long waveguide with 35 mW of on‐chip

Black Phosphorus/Ferroelectric CuInP2S6 Heterostructures Empowering Nonvolatile Photonic Convolutional Computing

Laser &Photonics Reviews, EarlyView.
ABSTRACT The growing demands of artificial intelligence require new energy‐efficient and nonvolatile computing paradigms. To meet this challenge, we demonstrate a foundational device platform for optical fiber computing that targets the signal decay and power consumption bottlenecks of conventional systems.

High‐Efficiency Graphene‐Silicon Slot‐Waveguide Microring Modulator at 1.5 and 2 µm Wavelength Bands

Laser &Photonics Reviews, EarlyView.
E/O modulators typically face a trade‐off between bandwidth and modulation efficiency. An integrated E/O modulator is presented that simultaneously achieves wideband, large bandwidth, and high modulation efficiency operation by embedding a partially overlapped double‐layer graphene on a compact silicon slot‐waveguide microring resonator.

Comb‐Driven Coherent Optical Transmitter for Scalable DWDM Interconnects

Laser &Photonics Reviews, EarlyView.
A comb‐driven coherent optical transmitter on a Si/SiN platform enables scalable DWDM interconnects by integrating ultra‐compact microring‐assisted modulators and interleavers. High‐baud coherent signaling achieves 400 Gb/s per wavelength and >$>$1 Tb/s multi‐channel transmission, with projected >$>$10 Tb/s per fiber, offering a path toward energy ...

Epitaxial Integration of III–V Membrane Photodetectors With Lateral p–i–n Junctions on the Silicon‐On‐Insulator Waveguide Platform

Laser &Photonics Reviews, EarlyView.
Epitaxial growth forms III–V membranes directly atop the silicon waveguide layer on SOI, while in‐plane in situ doping defines lateral p–i–n InP/InGaAs junctions in a single growth step. The membrane photodetectors achieve 50 Gb/s NRZ‐OOK operation.

High‐Speed Integrated Graphene‐Silicon Slot‐Waveguide Electro‐Absorption Modulator at 2 and 1.5 µm Wavebands

Laser &Photonics Reviews, EarlyView.
A high‐speed, efficient, robust, and compact 2‐μm$\mathrm{\mu}\mathrm{m}$ waveband E/O absorption modulator based on a graphene‐silicon slot waveguide is demonstrated. This work represents a significant advancement towards the realization of high‐speed integrated E/O modulators for optical communication systems operating at the 2‐μm$\mathrm{\mu}\mathrm{
