Abstract
This paper presents an experimental investigation of a triple lasing wavelength of fiber laser employing bidirectional SOA incorporated with a tapered fiber which operates in the L-band region. This ring configuration comprises of a bidirectional semiconductor optical amplifier and a tapered fiber. Based on the results, a single mode tapered fiber in the configuration has the ability to enhance the wavelength performance in terms of the optical signal to noise ratio and its stability. This tapered optical fiber has a diameter waist of 12 μm, length waist of 10 mm and 5 mm for its uptaper length and downtaper length. Semiconductor optical amplifier injected current varies for 130 mA, 210 mA, and 300 mA to observe fiber laser performance in term of average output power and optical signal to noise ratio. This fiber laser can lase three wavelengths at 1576 nm, 1586 nm and 1596 nm. These triple wavelengths output exhibits an excellent performance by having the average optical signal to noise ratio of 44 dB, and average peak power is -13 dbm. Furthermore, fiber laser employing bidirectional SOA incorporated with a tapered fiber has efficient performance lasing wavelength stability over 60 minutes.
