Fully Tunable Bandpass Filter With Wide Bandwidth Tuning Range and Switchable Single/Dual Band

IEEE Access
In this paper, a fully tunable bandpass filter (BPF) with three states of filtering (single passband state, dual passband state and all-off state) is proposed, the proposed fully tunable BPF is cascaded by a tunable low pass filter section (LP) and a ...

Monolithic Silicon Photonic Transceiver for 160 km Multi‐Channel Quantum Entanglement Distribution in Fiber Network

Laser &Photonics Reviews, Volume 20, Issue 1, 8 January 2026.
The paper demonstrates a chip scale (4.5 x 4.5 mm2) silicon integrated system that is capable of distributing entangled photons over 160 km single mode fibers without dispersion compensations and external optical filters. The results highlight the potential for massive production and large‐scale deployed quantum integrated circuits for a future ...

An On‐Chip Elliptic Bandpass Filter With High Selectivity and High Stopband Attenuation Near the Passband Based on Stacked Series‐Parallel Topology

IET Microwaves, Antennas &Propagation, Volume 20, Issue 1, January/December 2026.
A high selectivity integrated passive device (IPD) on‐chip bandpass filter is presented. The stacked series‐parallel topology is employed to generate two transmission zeros and a transmission pole to maintain high selectivity and high stopband attenuation near the passband.

Quad-mode dual-band bandpass filter based on a stub-loaded circular resonator

EURASIP Journal on Wireless Communications and Networking, 2019
In this paper, a quad-mode dual-band bandpass filter (BPF) only using a stub-loaded circular resonator is presented. The odd- and even-mode resonant frequencies can be easily computed and flexibly controlled by the radius of the circle and the two sets ...

Anisotropic Second‐ and Third‐Harmonic Hermite–Gaussian Beam Generation with NbOI2 Holograms

Advanced Photonics Research, Volume 6, Issue 12, December 2025.
Anisotropic second‐ and third‐harmonic Hermite–Gaussian (HG) beam generation is demonstrated with ultrathin NbOI2 grating holograms to produce the nonlinear HG01 and HG10 modes with high anisotropy ratios. The relative magnitudes of the second‐ and third‐order nonlinear susceptibility tensor elements of NbOI2 crystal are extracted. These demonstrations
