Title: Nucleic acid respiratory syncytial virus vaccines
Inventor: KLEIN MICHEL H
IPC: A61K35/76
Filed: 2000-03-03
Abstract: Non-replicating vectors containing a nucleotide sequence coding for an F protein of respiratory syncytial virus (RSV) and a promoter for such sequenc e, preferably a cytomegalovirus promoter, are described for in vivo immunizatio n. The nucleotide sequence encoding the RSV F protein lacks a sequence encoding  the homologous signal peptide but possesses a heterologous signal peptide enhancing RSV F protein expression. Such non-replicating vectors, including plasmids, also may contain a further nucleotide sequence located adjacent to  the RSV F protein encoding sequence to enhance the immunoprotective ability of the RSV F protein when expressed in vivo. Such non-replicating vectors may b e used to immunize a host against disease caused by infection with RSV, including a human host, by administration thereto, and may be formulated as immunogenic compositions with pharmaceutically-acceptable carriers for such purpose. Such vectors also may be used to produce antibodies for detection o f RSV infection in a sample.

Title: Quantum well intermixing
Inventor: TAM SIU CHUNG
IPC: G02B6/12
Filed: 2001-03-02
Abstract: The present invention provides a novel technique based on gray scale mask patterning (110), which requires only a single lithography and etching step (110, 120) to produce different thickness of SiO2 implantation mask (13) in selected regions followed by a one step IID (130) to achieve selective area intermixing. This novel, low cost, and simple technique can be applied for the fabrication of PICs in general, and WDM sources in particular. By applying a gray scale mask technique in IID in accordance with the present invention, the bandgap energy of a QW material can be tuned to different degrees across a wafer (14). This enables not only the integration of monolithic multiple-wavelength lasers but further extends to integrate with modulators and couplers on a single chip. This technique can also be applied to ease the fabrication and design process of superluminescent diodes (SLDs) by expanding the gain spectrum to a maximum after epitaxial growth.
