碩士 === 元智大學 === 光電工程研究所 === 97 === In the first part of this thesis, using multi-mode Fabry-Perot laser without external-injection for wavelength conversion is demonstrated. The input wavelength can be converted at 2.5 Gb/s by the converter and the power penalty of 3.5 dB is observed at the bit error rate (BER) of 10-9. In the second part, tunable dual-wavelength fiber laser using optical-injection Fabry-Perot laser is demonstrated. The dual-wavelength tuning range is 39.49 nm. And the mode spacing of the dual-wavelength can be tuned from 1.32 to 39.49 nm. In the third part, multiwavelength erbium-doped fiber ring laser employing Fabry-Perot etalon inside cavity operating in room-temperature is demonstrated. The proposed ring laser using a Fabry-Perot etalon inside a linear cavity and employing the accurate fiber cavity length to satisfy the least common multiple number for generating multiwavelength in C-band at room temperature. When the proposed laser satisfies the output conditions, the lasing wavelength bands located at 1541.02, 1551.32 and 1562.03 nm, respectively, are observed. And the wavelength separation in each band is 0.34 nm.
