摘要： PROBLEM TO BE SOLVED: To provide a method for driving a surface emitting semiconductor laser which can be driven at high speed while reducing power consumption.
SOLUTION: A VCSEL (vertical-cavity surface-emitting laser diode) includes an active region that generates light, a resonator structure disposed such that it sandwiches the active region, and a driving electrode that provides power to the active region. The VCSEL has an internal resistance defined by voltage and current applied to the driving electrode. The method for driving the VCSEL includes a step of applying a modulation signal to the driving electrode of the VCSEL, in which the modulation signal has a current amplitude I
F defined by a current value I
L of a low level and a current value I
H of a high level. The modulation signal is in a negative gradient region in which the internal resistance decreases in contrast to the increase of the current.
