Abstract

We show experimentally and theoretically that a center frequency shift occurs when an external cavity laser is directly modulated. The shift may be observed even when the frequency deviation is small compared to the roundtrip frequency of the external cavity and can qualitatively be explained by a reduction in the effective feedback level due to modulation. The frequency shift has been measured as a function of modulation frequency and current, and frequency shifts up to 350 MHz were observed.
