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 ...

Enhancing FSO‐DWDM Performance Through Compensation Strategies

Engineering Reports, Volume 7, Issue 12, December 2025.
This study investigates the performance of free space optics (FSO) with dense wavelength division multiplexing (DWDM) systems, focusing on the impact of channel number and compensation strategies on bit error rate (BER). Results show that post‐compensation significantly improves performance, extending the system's range from 3 to 5 km.

Robust transport of high‐speed data in a topological valley Hall insulator

Nanophotonics, Volume 14, Issue 27, Page 5047-5057, December 2025.
Abstract Photonic topological insulators provide robust transport of light, enabling interesting phenomena such as unidirectional light propagation and immunity to disorder. The discovery of how to effectively break time reversal symmetry was an important development in the field of photonic topological insulators. Knowledge on how to implement designs

Monolithic temperature‐insensitive high‐Q Ta2O5 microdisk resonator

Nanophotonics, Volume 14, Issue 27, Page 5475-5483, December 2025.
Abstract We demonstrate a temperature‐insensitive high‐Q tantalum oxide (Ta2O5) microdisk resonator fabricated using electron‐beam lithography and inductively coupled plasma reactive‐ion etching. The microdisks exhibit a loaded Q‐factor of 4.25 × 105 at 1,550 nm, which more than doubles (∼9.3 × 105) following thermal annealing at 600 °C.

Non‐Markovian Dynamics in Fiber Delay‐Line Buffers

Advanced Quantum Technologies, Volume 8, Issue 8, August 2025.
A qubit‐fiber birefringence‐reservoir model is proposed to explore the non‐Markovian dynamics of the fiber‐based buffered photon and its paired photon. The non‐Markovian probability function is obtained by performing full quantum state tomography. The probability function fits well with experimental data and physical values.
