Latest Patents

One of Oku's latest patents focuses on a semiconductor optical device and its fabrication method. This innovative device includes a semiconductor substrate and a stacked body formed by at least a first cladding layer, an active region, and a second cladding layer. Both sides of the stacked body are buried by a burying layer made from a semi-insulating semiconductor crystal. The burying layer consists of a first layer adjacent to both sides of the stacked body and a second layer adjacent to the first layer. The first layer incorporates Ru as a dopant, while the composition of the second layer differs from that of the first layer, or its dopant is different. The design allows for the active region's width to be smaller than that of the cladding layers, and a Ru-doped semi-insulating layer is positioned between the burying layer and the active region on both sides.
