Patent number: 7403551Abstract: The aim of the invention is to adjust the operating point of a laser that can be modulated by a data signal. The operating point of the laser is adjusted by regulating a direct current flowing through the laser; whereby said direct current correlates with the optical characteristics of the laser. In order to carry out said adjustment, the direct current is controlled above an alterable threshold current. A differential current defined from the difference between the direct current and the threshold current or a variable correlating with the differential current is adjusted to a constant value or one that is solely dependent on temperature for the adjustment of said operating point.Type: GrantFiled: September 5, 2001Date of Patent: July 22, 2008Assignee: Finisar CorporationInventors: Franz Auracher, Robert Scholz

Patent number: 5541755Abstract: Apparatus and methods are disclosed for readjusting a modulation shift of a transmission light modulated optical signal. In these systems and methods, a first modulated portion of the modulated transmission light is removed to obtain a first modulated signal which is divided into first and second light beams. The first light beam is delayed by a specific delay time and the first and second light beams are coherently superimposed to obtain an optical superposition signal which is detected to produce a detector signal that is proportional to a power of the superposition signal. An error signal is subsequently generated from the detector signal which is representative of a modulation shift from a desired shift value which is used for substantially correcting a modulation of the transmission light.Type: GrantFiled: September 30, 1994Date of Patent: July 30, 1996Assignee: Siemens AktiengesellschaftInventors: Reinhold Noe, Franz Auracher
