We report the first demonstration to our knowledge of an ultrabroad emission laser using InGaAs GaAs quantum dots by cycled monolayer deposition. The device exhibits a lasing wavelength coverage of 40 nm at an 1160 nm center wavelength at room temperature. The broadband signature results from the superposition of quantized lasing states from highly inhomogeneous dots.
