Tunable Single Wavelength fiber laser with a wide tuning range, 75 nm by using a parallel scheme,is demonstrated. This tunable laser capable of generating any lasing channels within 1495 nm until 1565 nm that covers S-band and C-band regions. By using the idea of connecting two amplifiers in a ring cavity with serial and parallel schemes, a new scheme with an additional C-band amplifier issuccessfully demonstrated with output power and SMSR values improvement as compared to the two previous schemes. By utilizing Broad Band FBG (operated in C-band) before the S-band EDF,it acts as a reflector and a transmitter for the Amplified Spontaneous Emission (ASE) in the C-band and S-band regions, respectively. The proposed scheme acts as an output power stabilizer for the laser source tunability from S-band to the C-band region, mainly within 1510 nm -1525 nm of tuning range.
