Abstract

One-step quantum wire (QWR) gain coupled (GC) distributed feedback (DFB) lasers in direction parallel to the wire was fabricated. The V-grooves, fixed at the third-order-diffraction gratings were formed on an GaAs substrate using homemade holographic photolithography and wet chemical etching. No two mode degeneracy is found and a stable lasing operation is achieved in the wire direction at relatively low threshold currents under room temperature (RT) pulsed operation.
