Single Longitudinal Mode Properties of External Cavity Tapered and Straight Broad-Stripe Lasers with Bandpass Filter

概要

論文の詳細を見る
The single longitudinal mode properties of external cavity broad-stripe lasers combined with bandpass filters have been investigated. With tapered amplifiers, the emission wavelength changes periodically as a function of the driving current due to shifting of the internal Fabry-Perot mode and the narrow bandwidth of the filter. In contrast, with straight amplifiers, the peak wavelength monotonically varies. This is due to changes in the transverse mode of straight amplifiers.
