摘要: A system for handling semiconductor and electronic elements secured to an adhesive surface is provided. According to one aspect of the invention, a vacuum is applied through holes in a loading base. Under the influence of the vacuum, the adhesive film is pulled down toward the loading base and stretched around a pick rod so that the adhesive film is peeled away from the element. Thus, adhesive contact between the film and the element is reduced and a vacuum pick or collet is able to lift the element from the adhesive film with minimal force applied to the surface of the element.

摘要: A reflection filter is disposed on a solid state laser so as to preferentially reflect TE or TM modes and to suppress oscillation within the resonator of the non-reflected modes. In one embodiment, the filter includes a layer having a plurality of grooves which may be straight and parallel or curved to approximate the mode shape. In another embodiment, the filter includes a polarization sensitive film, without grooves, which either absorbs or transmits the undesired mode. Specifically described is a buried heterostructure semiconductor DFB laser with such a reflection filter formed on at least one facet thereof.
