Latest Patents
One of Yoshio Noguchi's latest patents involves 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 next 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 distinct from that of the first layer. The device can also be configured such that the width of the active region is smaller than that of the cladding layers of the stacked body. Additionally, a Ru-doped semi-insulating layer is provided in the space between the burying layer and the active region on both sides of the active region.
