High‐Power Continuous‐Wave Optical Waveguiding in a Semiconductor Nanowire
Advanced Photonics Research, Volume 7, Issue 9, September 2026.An in‐line fiber–nanowire–fiber configuration provides efficient coupling of 1550 nm continuous‐wave light into and out of a single CdS nanowire. The output power increases linearly with input power, reaching 1.8 W and corresponding to a guided power of 2.5 W, demonstrating watt‐level continuous‐wave optical waveguiding in a subwavelength semiconductor

Stimulated Forward Brillouin Scattering in Subwavelength Grating Silicon Membranes
Laser &Photonics Reviews, Volume 20, Issue 17, 3 September 2026.This work proposes a novel strategy to achieve large Brillouin scattering with independent control of the optical and mechanical modes using subwavelength silicon membranes. We experimentally demonstrate remarkably high Brillouin gain, resulting in an on/off Stokes gain of 3 dB and anti‐Stokes loss of 4 dB in a 6 mm‐long waveguide with 35 mW of on‐chip

Guangtongxin yanjiu, 2019 针对现有的光时域反射仪（OTDR）在监测带有掺铒光纤放大器（EDFA）的长途多跨段光纤链路时,为克服EDFA增益的波动需增加一个额外的补光来保持功率稳定的问题,文章基于线性调频OTDR提出了一种无需补光穿越EDFA的长途多跨段光纤监测技术。该技术利用线性调频准连续光作为探测光,可以避免EDFA增益的波动。同时通过分数域傅里叶滤波来去除级联EDFA累积的自发辐射白噪声,从而提高接收信号的信噪比。实验结果表明,该技术能够准确地测出中长途多跨段光纤链路中EDFA和连接点处的反射事件。

Ultrahigh‐Order Harmonic Mode‐Locked Optoelectronic Oscillator
Laser &Photonics Reviews, Volume 20, Issue 17, 3 September 2026.This article demonstrates a record‐breaking microwave frequency comb generator using an ultrahigh‐harmonic‐order mode‐locked optoelectronic oscillator. By integrating dual recirculating loops into a low‐coherence system, the researchers achieved a harmonic order of 956 with superior noise suppression.
