Modulation current compensation of a laser for fixed extinction ratio using Ith and Ibias

摘要

According to an exemplary embodiment of the present invention, a method of controlling an optical device includes calculating a slope of a characteristic curve and adjusting a modulation current based on said slope. ;According to another exemplary embodiment of the present invention, an apparatus for controlling an optical device includes a driver, which inputs a modulation current, and a controller which calculates the modulation current based on a slope of a characteristic curve.
