Title: Optical fiber amplifier having a gain flattening filter
Inventor: LUTZ DIRK
IPC: H04B10/25
Filed: 1998-06-15
Granted: 2001-06-23
Abstract: An optical fiber amplifier of the erbium type is intended to amplify light signals within a wavelength band, e.g. in the range of 1540-1555 nm. The active optical fiber (21, 23, 35) receives light signals to be amplified and pump light of a first pump wavelength from a pump source (9). A gain flattening filter (39) is connected in the active optical fiber length. A noise filter (37) is also connected in the active optical fiber, not more closer to the output end of the active fiber than the gain flattening filter (39). The noise filter (37) blocks light waves having wavelengths around the ASE gain peak and the gain filter (39) attenuates wavelengths within the useful signal band in order to produce a flat gain curve. The introduction of the noise filter (37) increases the total amplification of the amplifier.

Granted: 2001-09-01
Abstract: A straight, thin, monolithic abrasive wheel formed of hard and rigid abrasive grains and a sintered bond including a metal component and an active metal component exhibits superior stiffness. The metal component can be selected from among many sinterable metal compositions. The active metal is a metal capable of reacting to form a bond with the abrasive grains at sintering conditions and is present in an amount effective to integrate the grains and sintered bond into a grain-reinforced composite. A diamond abrasive, copper/tin/titanium sintered bond abrasive wheel is preferred. Such a wheel is useful for abrading operations in the electronics industry, such as cutting silicon wafers and alumina-titanium carbide pucks. The stiffness of the novel abrasive wheels is higher than conventional straight monolithic wheels and therefore improved cutting precision and less chipping can be attained without increase of wheel thickness and concomitant increased kerf loss.
