Single frequency erbium fiber external cavity semiconductor laser

By W.H. Loh, R.I. Laming and M.N. Zervas


A novel external cavity configuration for stable single frequency operation of the semiconductor laser is demonstrated. By using an erbium doped fiber as the external cavity, longitudinal mode-hopping is suppressed, ensuring single frequency operation. Employing a 3m long fiber cavity, resolution-limited optical linewidths of a kHz are obtained
