Optimized HR-AR-DFB laser structures are proposed foreseeing
their use in directly modulated optical communication systems. They present, simultaneously, high single-longitudinal-modeyield, stable
single-longitudinal mode operation, high power efficiency and stable emitted wavelength. Lasers harder to manufacture were
previously proposed elsewhere and did not
succeed in achieving such high performances. A detailed assessment of the proposed lasers is presented and discussed.
