Latest Patents

One of Dutta's latest patents involves gallium oxide coatings for optoelectronic devices using electron beam technology. This invention describes an optoelectronic III-V or II-VI semiconductor device that features a thin film coating with optical characteristics that provide low midgap interface state density. Additionally, a field effect device for inversion channel applications on III-V semiconductors is included, which comprises a thin dielectric film that offers the necessary interface characteristics. The thin film is applicable for passivation of states on exposed surfaces of electronic III-V devices. It consists of a uniform, homogeneous, dense, stoichiometric gallium oxide (Ga2O3) dielectric thin film, fabricated by electron-beam evaporation of a single crystal, high purity Gd3Ga5O12 complex compound on semiconductor substrates maintained at temperatures ranging from 40°C to 370°C and at background pressures at or above 1×10^-10 Torr.

Another significant patent is an article comprising a tunable semiconductor laser. This tunable laser typically functions as a surface emitting laser that includes a multilayer structure comprising a lower Bragg reflector and an active region. A layer of electro-optic material, typically liquid crystal material, is in contact with the top surface of the multilayer structure, with means provided for applying a voltage across this layer. In one embodiment, the layer is positioned inside the laser cavity, allowing for tunable laser wavelength. In another embodiment, the laser is a Z-laser that focuses the output radiation, with the multilayer structure also including an upper Bragg reflector. This design allows for tunable focal length, making the lasers advantageous for various applications, including wavelength division multiplexed and optically amplified optical fiber communication systems.
