Patent number: 7397985Abstract: A method for making a high-power fused collimator, and a fused collimator made thereby, are provided. A fused collimator is provided that includes an end of a stripped end portion of an optical fiber fused to a proximal face of a silica lens. In an embodiment, a joint formed by the fiber end and the silica lens proximal face is substantially surrounded with a solder glass in a melted form. A cross-sectional area of the solder glass decreases proximally from a distal edge adjacent the lens to a proximal edge located along the fiber's stripped end portion. The solder glass is permitted to harden, forming a fused collimator. In another embodiment, a ferrule surrounds the fiber stripped end portion, and an adhesive is applied to the ferrule's proximal face to surround the fiber. The lens-ferrule joint is surrounded with solder glass, which is then surrounded with a silica sleeve.Type: GrantFiled: December 5, 2006Date of Patent: July 8, 2008Assignee: Lightpath Technologies, Inc.Inventors: David A.

Patent number: 6278656Abstract: A device for manipulation of acoustic waves is provided, comprising a functionally-graded material for interposing between a source of the acoustic waves and a target, which may be a detector of manipulated acoustic waves. The functionally-graded material has a gradient in acoustic wave velocity which is obtained by the generation of a gradient in at least one of the following properties: elastic modulus, Poisson's ratio, and density, that is perpendicular to a direction of propagation of the acoustic waves. The gradient is axial. Biaxial acoustic velocity gradients may be used for focusing/waveguiding (high-low-high) or dispersing (low-high-low), while monoaxial acoustic velocity gradients may be used for wave steering. Also in accordance with the present invention, a method of making the device is provided, comprising: (a) providing the source of acoustic waves; (b) providing the target for acoustic waves, e.g.Type: GrantFiled: September 2, 1999Date of Patent: August 21, 2001Assignee: LightPath Technologies, Inc.Inventors: Vineet Tyagi, David A.
