The addition of nitrogen to III–V alloys has been widely studied as a method of modifying the band gap for mid-infrared (IR) applications. Lattice matching these alloys to convenient substrates such as GaSb, however, is challenging due to the signi

A new type of waveguide-based demultiplexer is made in a GaAs-AlGaAs system with a grating-assisted codirectional coupler structure to pick out the wanted wavelength. Two waveguides that are made vertically coupled are fabricated using a special back

Infrared (IR) detector materials based on III‐V semiconductors are an affordable alternative to HgCdTe, which is the current material of choice for most high performance IR focal plane array systems fielded in the Army. Based on the assumption that

We examined diets of Lesser Scaup (Aythya affinis) during midwinter (N = 41) in southwestern Louisiana (1986), and during spring (N = 57) and fall (N = 48) in northwestern Minnesota (1984–1988). Diets of males and females generally were similar dur
