Enhancement of Brillouin stokes powers in multiwavelength fiber laser utilizing band‐pass filter

Abstract

combination with the tunable filter function, the linear-cavity fiber laser can stably lase two wavelengths simultaneously and can be easily tuned dynamically. The relationship between the FPLD driving current and the SMSR of this dual-wavelength laser were also discussed.

Impact of Booster Section Length on the Performance of Linear Cavity Brillouin-Erbium Fiber Laser

“…Increasing the number of the Stokes line generation was another goal of many researchers [13][14][15]. A simple and efficient method to increase the number of generated Stokes lines was proposed by [16] insering a short length of passive EDF into the cavity.…”

Capacity enhancement of virtual‐mirror‐based multiwavelength Brillouin‐erbium fiber laser

“…Multiwavelength fiber lasers have attracted a lot of interests in recent years and found many applications in optical spectroscopy , optical sensors , microwave and millimeter‐wave signal generations , and for wavelength division multiplexing systems . Different methods have been demonstrated by many researchers to generate multiwavelength fiber lasers . Among these methods, the multiwavelength Brillouin‐erbium fiber lasers (BEFLs) have demonstrated distinguished characteristics such as precise wavelength spacing, narrow linewidth source, and stable multiwavelength operation at room temperature.…”

“…To overcome this problem, the self‐lasing modes can be suppressed by incorporating a tunable bandpass filter (TBF) in the laser cavity . The wide tuning range was achieved by manipulating the cavity modes and adjusting the optimum BP wavelength to achieve the highest number of laser lines.…”
