Low‐Crosstalk Silicon Photonic Switch Fabrics for AI Datacenters and High‐Capacity Optical Interconnects: Device‐Level Origins and Mitigation

open access: yesLaser &Photonics Reviews, EarlyView.
Scaling silicon photonic switch fabrics for AI datacenters is fundamentally constrained by accumulated crosstalk, insertion loss, and device‐level non‐idealities. This work establishes a device‐to‐link‐to‐system framework that connects the physical origins of crosstalk to practical mitigation strategies across device, circuit, and control levels.

The Research of RF MEMS Bandpass Filter on the basis of the Microwave Bandpass Filter

open access: yes, 2014
摘要 本篇論文主要是應用微機電製程之特性與方法設計射頻微機電帶通濾波器。首先,利用玻璃纖維板設計各種不同種類之帶通濾波器(Bandpass Filter)或低通濾波器(Lowpass Filter),以觀察濾波器之差入損失(Insertion Loss)及返回損失(Return Loss)與基板之特性關聯。其次,以抑制二次、三次諧波為研究重點,設計各種新式帶通濾波器,其中含步階式阻抗帶通濾波器(Stepped Impedance Resonator Bandpass Filter)、

Transmission‐Mode Silicon‐Rich Nitride Mie‐Void Metasurfaces in the Visible

open access: yesLaser &Photonics Reviews, EarlyView.
Transmission‐mode Mie‐void metasurfaces are demonstrated in silicon‐rich nitride, where localized void resonances hybridize with slab‐guided and Fabry–Pérot‐like modes in a finite film, producing a quantified avoided crossing between coupled modes. Controlled void depth tunes the visible transmission spectrum, enabling structural color and spatial ...

Segment‐Chirped Periodically Poled Lithium Niobate Waveguides for Broadband Supercontinuum Generation

open access: yesLaser &Photonics Reviews, EarlyView.
Segment chirped periodically poled lithium niobate waveguides enable efficient and broadband quasi phase matching to generate a coherent three octave supercontinuum spanning 320 2600 nm. This practical strategy advances compact ultraviolet to mid infrared sources for spectroscopy, frequency metrology, and nonlinear photonics.
