Edge-filtering-based high-frequency parameter characterization for MG-Y lasers
The parameter characterization of Modulated Grating Y-branch (MG-Y) tunable lasers is essential for ensuring stable and precise wavelength output. To meet the high sampling rate demands during high-frequency laser tuning, this paper proposes an edge-filtering-based characterization method tailored for MG-Y lasers. The method employs a Tunable Fiber Filter(TFF) to perform edge filtering on the laser output. The filtered optical power is detected by a Photo-Diode(PD) and converted into a voltage signal, enabling a sampling rate significantly higher than that of conventional instruments such as spectrometers or wavelength meters. Utilizing the laser’s low-frequency tuning path, a Particle Swarm Optimization (PSO) algorithm is applied to iteratively determine the optimal control parameter sets for designated wavelength targets. This enables the characterization of MG-Y lasers under high-frequency tuning conditions and supports the generation of a current-to-wavelength Look-Up Table (LUT). Experimental results demonstrate that the constructed LUT contains 2001 wavelength points over a 40 nm tuning range, achieving a wavelength accuracy of ±5.8 pm with a standard deviation of 2.8 pm at a tuning frequency of 200.71 kHz, thereby meeting the performance requirements for subsequent Fiber Bragg Grating (FBG) demodulation applications.
期刊介绍:
Optics and Lasers in Engineering aims at providing an international forum for the interchange of information on the development of optical techniques and laser technology in engineering. Emphasis is placed on contributions targeted at the practical use of methods and devices, the development and enhancement of solutions and new theoretical concepts for experimental methods.
Optics and Lasers in Engineering reflects the main areas in which optical methods are being used and developed for an engineering environment. Manuscripts should offer clear evidence of novelty and significance. Papers focusing on parameter optimization or computational issues are not suitable. Similarly, papers focussed on an application rather than the optical method fall outside the journal''s scope. The scope of the journal is defined to include the following:
-Optical Metrology-
Optical Methods for 3D visualization and virtual engineering-
Optical Techniques for Microsystems-
Imaging, Microscopy and Adaptive Optics-
Computational Imaging-
Laser methods in manufacturing-
Integrated optical and photonic sensors-
Optics and Photonics in Life Science-
Hyperspectral and spectroscopic methods-
Infrared and Terahertz techniques
