Peak gain wavelength tuning via the gain‐lever effect is demonstrated in segmented contact InP quantum dot Fabry–Perot lasers. A tuning range of 6.5 ± 0.1 nm was recorded in the lasing spectra of a 1.9 mm long broad area device operating at 22°C. The authors clarify the nature of the tuning mechanism and identify the critical material and device parameters that determine the limits of the wavelength tuning range.
