This paper proposes a pattern recognition method for φ-OTDR based on self-reference features, where machine learning is applied to classify the vibration monitored. The φ -OTDR collects the light amplitude–time–space sequence, establishes a ref

The self-healing property of laser beams with special spatial structures is of great interest. We take the Hermite–Gaussian (HG) eigenmode as an example, theoretically and experimentally investigating the self-healing and transformation characteris

We propose and theoretically study a two-section high-power distributed feedback (DFB) laser with three equivalent phase shifts (3EPSs). A tapered waveguide with a chirped sampled grating is introduced to amplify the output power and keep a stable si

A microwave photonics instantaneous frequency measurement scheme with 14 channels based on an optical frequency comb (OFC) is proposed. In this scheme, a 14-line flat OFC is generated by cascading a dual-parallel Mach–Zehnder modulator (DPMZM) with
