Dual-Band and Multi-State Polarization Conversion Using aTerahertz Symmetry-Breaking Metadevice
Nanomaterials, 2023 We numerically and experimentally demonstrate a terahertz metadevice consisting of split-ring resonators (SRRs) present within square metallic rings. This device can function as a dual-band polarization converter by breaking the symmetry of SRRs. Under x-

Modular Photonic-Integrated Device for Multi-Band Wavelength-Selective Switching
2022 27th OptoElectronics and Communications Conference (OECC) and 2022 International Conference on Photonics in Switching and Computing (PSC), 2022 We propose a Silicon Photonics based WSS for S+C+L bands, independently routing any input channel to the desired output fiber. BER and OSNR for a system with 30 total channels are evaluated with Synopsys Optsim.
