| Title: Er-doped fiber lasers based on microstructured fibers | |
| Abstract: Microstructured Fiber (MSF) is also called Photonic Crystal Fiber (PCF) or Holy Fiber (HF). In 1996, The first PCF was successfully fabricated. Compared to traditional fibers, MSFs have a lot of advantages，such as endlessly single-mode guiding, low optical losses, polarization effects and high birefringence, and so on. Er-doped Fiber lasers （EDFL）play a significant role in plenty of fields, ranging from optical communications to mechanical processing and laser biomedicine, owing to their high beam quality, low cost, and excellent heat dissipation properties. Consequently, EDFL have become a research hotspot and caused enormous interest and attention in the world. However, the homogeneous gain broadening of Er-doped fiber suppress the multi-wavelength operation at room temperature. To weaken this effect, various methods have been proposed to obtain stable multi-wavelength lasers output. Among them, inserting an optical filter based on microstructure optic fiber is one of the highest efficient and simplest method to produce multiple wavelengths. In this presentation, we summarize and analyze using diverse MSF such as Bragg fiber, multi-core photonic crystal fiber, suspended-core fiber, photonic crystal fiber filled with liquid, hollow-core fiber to achieve multi-wavelength lasing outputs. Finally, future challenges and perspectives of the microstructure optic fiber filters based multi-wavelength fiber laser are discussed and addressed. | |
