| Abstract: | In this paper, amplifying mechanism, manufacturing processes, and technology evolution of Erbium Doped Waveguide Amplifier (EDWA) are presented, and a comprehensive comparison is made among Erbium Doped Fiber Amplifier (EDFA), Erbium Micro Fiber Amplifier (EMFA) and Semiconductor Optical Amplifier/Linear Optical Amplifier (SOA/LOA). Gain limiting factors, such as co-operative upconversion due to high doped concentration, and excited state absorption, are briefly discussed. The means to reduce cost, insert loss, and dimensions of EDWA devices is proposed. A prospect is made on applications and development of EDWA in optical communication system and integrated optic devices. |
