Abstract :
Distributed feedback (DFB) quantum wire (QWR) lasers were fabricated on V-grooved substrates. After characterizing the wire emission using electro- and photoluminescence techniques, DFB laser cavities incorporating such QWRs with an emission wavelength matched to the Bragg wavelength were designed and fabricated. The selectivity of lasing wavelength of the DFB cavity was used to obtaining DFB operation at the emission wavelength of the wire up to 145 K under pulsed conditions. The emission from the parasitic quantum well structures was suppressed due to the forbidden DFB gap
