In this paper, we propose the dynamic P-V curve for modulator and P-I curve for laser diode, and present a simple approach to deriving the curves from the small-signal frequency responses measured using a microwave network analyzer. The linear response range, modulation efficiency, optimal driving conditions at different frequency can, therefore, be determined. It is demonstrated that the large-signal...
This paper presents the estimation of the frequency responses and chirp parameters of directly modulated lasers, and the measurement of linewidth of tunable laser and frequency response of photodetector based on optical and electrical spectrum analysis.
