研究目的
Demonstrating a semiconductor optical amplifier (SOA) based 1064 nm fiber ring laser with high optical signal-to-noise ratio (OSNR) and applying it to sense stretch, squeeze, and temperature variation with high linearity and a large dynamic range for remote sensing applications.
研究成果
The 1064 nm SOA-based fiber ring laser demonstrates stable performance with high OSNR and is effectively applied to sense environmental parameters such as stretch, squeeze, and temperature variation. The system shows high linearity and a large dynamic range, making it suitable for remote sensing applications.
研究不足
The wavelength variation is limited within 10.68 nm to prevent fiber breakage due to fatigue damage under repeated stretching and squeezing. The dynamic range is 10 km under the criterion of 10 dB OSNR.
1：Experimental Design and Method Selection:
The study involves the construction of a SOA-based fiber ring laser operating at the 1064 nm band, incorporating a SOA, a polarization controller, a tunable FBG (TFBG), and an optical circulator (OC). The performance stability is measured over six hours.
2：Sample Selection and Data Sources:
The SOA used is a traveling-wave device with anti-reflection coating on both cavities ends. The FBG's reflectivity and reflective wavelength are specified.
3：List of Experimental Equipment and Materials:
Includes SOA, polarization controller, TFBG, OC, standard fiber (SMF-28), optical switches (OSWs), and power meter.
4：Experimental Procedures and Operational Workflow:
The generated power is controlled by adjusting the SOA bias current. The TFBG is placed on an axial stretch/strain platform for stretch and squeeze measurements. Temperature sensing is conducted by placing the FBG under water with varying temperatures.
5：Data Analysis Methods:
The lasing spectrum, OSNR, and wavelength shifts are analyzed to evaluate the laser's performance and sensing capabilities.
