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.

Photon Pair Generation in Silicon Micro-Ring Resonator with Reverse Bias Enhancement [PDF]

, 2012
Photon sources are fundamental components for any quantum photonic technology. The ability to generate high count-rate and low-noise correlated photon pairs via spontaneous parametric down-conversion using bulk crystals has been the cornerstone of modern

Optical neuromorphic computing via temporal up‐sampling and trainable encoding on a telecom device platform

Nanophotonics, Volume 14, Issue 16, Page 2761-2778, August 2025.
Abstract Mapping input signals to a high‐dimensional space is a critical concept in various neuromorphic computing paradigms, including models such as reservoir computing (RC) and extreme learning machines (ELM). We propose using commercially available telecom devices and technologies developed for high‐speed optical data transmission to implement ...

A reconfigurable multi‐channel on‐chip photonic filter for programmable optical frequency division

Nanophotonics, Volume 14, Issue 15, Page 2619-2631, August 2025.
Abstract Recent advancements have broadened the application of photon filters based on Bragg gratings within optical communication networks and optical input/output interfaces. Traditional gratings, however, suffer from a fixed refractive index modulation distribution once manufactured, constraining their adaptability and flexibility.

On‐chip frequency‐bin quantum photonics

Nanophotonics, Volume 14, Issue 11, Page 1879-1894, June 2025.
Abstract Frequency‐bin encoding furnishes a compelling pathway for quantum information processing systems compatible with established lightwave infrastructures based on fiber‐optic transmission and wavelength‐division multiplexing. Yet although significant progress has been realized in proof‐of‐principle tabletop demonstrations, ranging from arbitrary ...

Ultimate low system dark count rate for superconducting nanowire single-photon detector [PDF]

, 2015
The dark count rate (DCR) is a key parameter of single-photon detectors. By introducing a bulk optical band-pass filter mounted on a fiber-to-fiber optical bench cooled at 3 K and blocking down to 5 micrometer, we suppressed the DCR of a superconducting ...

一种简单实用的调节RFA增益平坦的方法

Guangtongxin yanjiu, 2004
提出了一种用ASE宽带光源调节拉曼光纤放大器（RFA）增益平坦的简单方法.将该ASE宽带光源调节RFA增益平坦所得泵浦配置方案用于DWDM信号的放大,得到DWDM信号增益谱与相应波长处ASE信号的增益谱相近,且增益波动小于1dB.所用的方法结构简单,调节方便,可有效地调节利用RFA的DWDM系统增益平坦度,而不需要调节复杂、成本昂贵的DWDM信号源.
