چکیده انگلیسی
We experimentally demonstrated a new structure of a multiwavelength semiconductor optical amplifier (SOA) ring laser based on a fiber Sagnac loop filter that can generate up to 25 stable output lasing wavelengths at room temperature. By varying the length of a polarization-maintaining (PM) fiber within the Sagnac loop filter, the wavelength spacing between the output lasing wavelengths can be changed to a desired value. By tuning a polarization controller (PC) within the Sagnac loop filter, stable multiwavelength 1550-nm operation with up to 17 lasing lines within 3Â dB power level variation and with a wavelength spacing of â¼0.8Â nm was achieved. The optical signal-to-noise ratios (OSNRs) of all the lasing wavelengths are greater than 40Â dB.
