| Abstract(in English) | Distributed feedback lasers with deeply etched wirelike active regions exhibiting low threshold current of 0.7mA and differential quantum efficiency of 23%/facet were realized. For better performance, we propose new distributed reflector (DR) laser by applying the similar fabrication technology. This laser has active region and passive DBR region for asymmetric output property. The passive DBR region consists of narrow wire structure utilizing energy blue shift due to a lateral quantum confinement effect for low-loss waveguide and several sets of wires are introduced into the grating for higher index-coupling coefficient. As a result, we show that the threshold current I_th will be half of that of conventional structure, and differential quantum efficiency η_d from one side will be higher than that of conventional structure. |
