Patent number: 6801552Abstract: A method of controlling a tuneable laser that has been characterized with respect to one or more suitable laser operation points. Each operation point is determined by the manner in which the different laser sections are controlled, in order to operate the laser at a predetermined operation point. The voltage across the different laser section is determined for different operation points when controlling the laser, and the voltages across the different laser sections are held constant when the laser is in operation to maintain a predetermined operation point.Type: GrantFiled: May 13, 2002Date of Patent: October 5, 2004Assignee: ADC Telecommunications, Inc.Inventors: Björn Broberg, Markus Renlund

Patent number: 6587485Abstract: A method of evaluating a tuneable laser and determining suitable laser operation points, wherein the laser includes one or more tuneable sections in which injected current can be varied. A portion of the laser light output is divided into parallel paths, one part of which passes through a periodic filter, a second part of which is unfiltered, and a third part of which passes through a monotonic filter. The light power outputs from the respective paths are compared as sweep currents are injected into the tuning sections of the laser. When the ratios of the power outputs are within a predetermined range the tuning current combinations for those operating points are stored.Type: GrantFiled: January 2, 2002Date of Patent: July 1, 2003Assignee: Altitun, ABInventors: Markus Renlund, Lars Andersson
