    摘要： A sequential configuration of log.sub.2 n stages of birefringent elements are set forth. Each stage has a transfer function approximating a square wave, and successive stages have half periods. An input beam with n wavelength components would be demultiplexed into 2, 4 and finally n output beams at the output of the first, second, and log.sub.2 n stages, each output beam containing only one wavelength. Successive stages consist of two polarizing beam splitters between which is located their appropriate length of birefringent element to achieve the desired transfer function.

    摘要： High quality epitaxial layers of compound semiconductor materials can be grown overlying large silicon wafers by first growing an accommodating buffer layer on a silicon wafer. The accommodating buffer layer is a layer of monocrystalline oxide spaced apart from the silicon wafer by an amorphous interface layer of silicon oxide. The amorphous interface layer dissipates strain and permits the growth of a high quality monocrystalline oxide accommodating buffer layer. The accommodating buffer layer is lattice matched to both the underlying silicon wafer and the overlying monocrystalline compound semiconductor layer. Any lattice mismatch between the accommodating buffer layer and the underlying silicon substrate is taken care of by the amorphous interface layer. To further relieve strain in the accommodating buffer layer, at least a portion of the accommodating buffer layer is exposed to a laser anneal process to cause the accommodating buffer layer to become amorphous, providing a true compliant substrate for subsequent layer growth.

    摘要： An apparatus for measuring at least one selected physical condition of an animate subject is disclosed. The apparatus comprises: (a) a light source; (b) a light receiver that receives resultant light from the light source via the subject; and (c) an information processor connected with the light receiver. The processor receives indication of the resultant light from the light receiver and evaluates the indication to effect the measuring. The processor is implemented in a unitary structure with the light source and light detector that is borne upon a single silicon substrate. The apparatus may further comprise a first interface element coupled with the processor to facilitate communication with the light receiver, and a second interface element coupled with the processor that includes communication means for conveying messages to remote loci. The first and second interface elements are implemented in the unitary structure. The method of the present invention comprises the steps of: (a) providing an apparatus implemented in a unitary structure borne upon a single silicon substrate; and (b) evaluating the indication provided by the apparatus to effect the measuring. The unitary structure is comprised of a monolithic structure having a first portion implemented in silicon, and having a second portion implemented in at least one compound semiconductor material.

    摘要： A method for coupling light from one or more light-emitting devices into corresponding optical fibers includes placing the light-emitting devices on the top surface of a substrate and forming, by photolithographical means, on the top surface of said substrate V-grooves for holding fibers in precise relationship with said light-emitting devices. Additionally, alignment pedestals or posts are formed on said substrate in predetermined relationship to the light emitting devices and alignment V-grooves are photolithographically formed on the top surface of said substrate parallel to said fiber V-grooves. The substrate is cleaved into two sections and said sections are assembled in orthogonal relationship with the section containing the light-emitting devices and alignment posts section being secured to the section containing the fiber and alignment V-grooves so that said posts fit into said alignment V-grooves, thereby aligning the fiber V-grooves with the light-emitting devices.
