A semiconductor laser having a narrow emission bandwidth (≪1 Å) with center wavelength electronically tunable over a large spectral range is demonstrated for the first time. This electro‐optically tunable infrared semiconductor laser source should have interesting applications in, for example, optical communications systems, optical radar, and spectroscopy.
