    摘要： A laser package comprises a laser diode source (16) having a first Fabry-Perot cavity between a highly reflective back facet and low reflective front facet (17) for providing a first light output for an optical application. A light monitor (15) is positioned adjacent to the back facet and aligned to receive a second light output from the laser diode back facet. A pigtail fiber (14) having a lensed fiber input end (32A) is positioned from the laser diode front facet to form an optical coupling region and is aligned relative to the lasing cavity to receive the first light output into the fiber, the light output exiting the package for coupling to the application. A portion of the first light output from the lasing cavity is reflected off the lensed fiber input end with a portion directed back into the lasing cavity and another portion reflected off the laser diode front facet. The front facet forms with the lensed fiber input end a second Fabry-Perot cavity generating light which is periodically in and out of phase with the light generated in the first Fabry-Perot cavity due to changes in the length of the second Fabry-Perot cavity caused by package ambient temperature changes so that a tracking error is generated in a signal developed by the light monitor. Thus, this invention provides several ways to suppress the formation of the second Fabry-Perot cavity.

    摘要： A method and apparatus for carrying out real time thin film metrology is described. This method and apparatus employ the analysis of a number of output electromagnetic fields produced by the reflection of an input electromagnetic field from a number of surfaces of the thin film. Relative measurements, inclusive of displacement of the output fields and/or one or more aberrations associated with the output fields, are employed so as to provide measurement of various physical characteristics of the thin film. In particular, the method and apparatus allow for real time measurement of the thickness and relative tilt between the surfaces of the thin film to be made. The employment of a wavefront sensor further provides for the measurement of the topography of each of these surfaces to also be made.

    摘要： A support apparatus has a platform (1) for storage of fluorescent light bulb tubes (20) or other objects. The rotatable platform (1) requires relatively little floor space when stored, but provides convenient use of the platform (1) for the placing or retrieval of objects in storage. The platform (1) may also be used as a table (24). The platform (1) is rotatably coupled to a mount (2), which is movable between a first position in which the platform (1) is retained against rotation and a second position in which the platform (1) is rotatable so as to provide access to the platform (1). One embodiment is a double-sided drawer (1) which is stored on end then pulled out and rotated to the horizontal about its centre of gravity (9) for easy access to both sides of the drawer (20, 22) for storage of fluorescent bulbs. A ladder (4) is also provided having the support apparatus affixed.
