Reinoptischer Wellenlaengenkonverter unter Nutzung eines integrierten verstaerkungsstabilisierenden Lasers und Verfahren zur Herstellung

DE1005021829 B UPAB: 20060612 NOVELTY - A purely optical wavelength converter, to convert an optical data signal from one carrier wavelength ( Delta 1) to another carrier wavelength ( Delta 2), has an integrated amplification stabilizing laser to generate the second wavelength. Two separate monomodal active (LWLa) and passive (LWLp) optic fibers are arranged on a horizontal plane. DETAILED DESCRIPTION - A purely optical wavelength converter, to convert an optical data signal from one carrier wavelength ( Delta 1) to another carrier wavelength ( Delta 2), has an integrated amplification stabilizing laser to generate the second wavelength. Two separate monomodal active (LWLa) and passive (LWLp) optic fibers are arranged on a horizontal plane. The passive optic fiber has two ports (A,B), and is coupled to the active fiber in an optical coupling zone (OKB). The active optic fiber is a laser (LAS) with one port (C) with a total mirror array (TOV) and a second port (D) with a partial mirror array (TEV). Port A or B is the entry for the data signal with the first carrier wavelength and the coupling zone length gives an amplified output of the data signal with the first carrier wavelength. Port D is the output port for the amplified and inverted data signal with the second carrier wavelength. The active optic fiber has at least one wavelength selective grid section (DBR) to stabilize the second carrier wavelength. USE - The optical wavelength converter is for use in increasing the flexibility of an optical communications network. ADVANTAGE - The system maintains a monomodal conversion with amplification stabilizing in a compact, simple and cost-effective converter module with a variety of applications
