Paper Abstract

We present a new method for measuring the semiconductor optical amplifier (SOA) linewidth enhancement factor, employing a configuration wherein the SOA is placed within a loss modulated fiber ring cavity operated in the FM laser regime. This allows an easy phase-index measurement in lasing operation at small modulation frequencies. A comparison with the conventional FM/AM technique enables independent measurement of the two underlying phase modulation mechanisms: thermal effects from the current modulation and gain-to-refractive index coupling.
