Patent CA-2353825-A1 (CA)
Title: Optical amplifier
Inventor: MIZRAHI VICTOR
IPC: H04J14/02
Filed: 2000-01-26
Abstract: Amplifier (700) includes an optical circulator (710) that receives an optical signal through a first port (710-1) and outputs the signal to doped fiber (712) through second port (710-2). Pump light is supplied to doped fiber (712) from pump laser (716) via a filtering element, such as in-fiber Bragg grating (714), which is typically designed to reflect light at the desired signal wavelength, but transmit other wavelengths. Accordingly, signal light output from second port (710-2) is reflected back through fiber (712) by grating (714) to second port (710-2) and experiences gain during each pass through fiber (712). The reflected light is then output from a third port (710-3) and passes through an optical dielectric filter (618) to receiver (315). Filter (618) can be provided to reduce ASE. In addition to or instead of filter (618), dielectric filter (735) can be provided at the output of pump laser (716). Typically, filter (735) is configured to transmit light at the pump laser wavelength (980nm or 1480nm, for example), but substantially reflect light at other wavelengths including ASE and signal light. Accordingly, pump laser (716) is effectively isolated from any ASE or signal light passing through grating (714) which could otherwise adversely affect performance of pump laser (716).

Abstract: An improved device for use in a conduit, such as a blood vessel, is provided. The device uniquely combines desirable properties from two distinct previous devices. The device (10) of the present invention assumes and is constrained to a first diametrical dimension (14) for insertion into the conduit. Once inserted and properly positioned in the conduit the device (10) expands to a second diametrical dimension within the conduit when the constraint is removed. The device (10) can then be dilated to one or more enlarged third diametrical dimensions by using a balloon catheter or similar device. The result is a device (10) that provides desirable properties of both self-expanding stents and balloon-expandable endoprostheses.      The device (10) can be employed in a variety of applications.
