摘要： The first and second light-emitting regions are provided on the light source. When the first optical fiber having the first core diameter is connected, the light emitted from the first light-emitting region enters the first core. When the second optical fiber having a greater core diameter than the first core diameter is connected, the lights emitted from the first and second light-emitting regions enter the second core. It is thus possible to connect the optical transmission device with multiple optical fibers having different core diameters. It is thus possible to provide the optical transmission device and the communication device, which are low in cost and high in convenience.

摘要： In an optical transmission apparatus in which a plurality of nodes are optically connected to one another via an optical transmission path, a light signal which is coded so that a mixture ratio of 1 and 0 constituting data is made close to 50% is transmitted through the optical transmission path. When a light signal is not emitted from all of the nodes, a dummy signal which is an AC-like signal is emitted to the optical transmission path. Therefore, an optoelectric conversion section can be always set to an active state, and the signal recognizability can be prevented from being lowered.

摘要： Provided is a method for driving a surface emitting semiconductor laser including 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 surface emitting semiconductor laser has an internal resistance defined by voltage and current applied to the driving electrode. The method includes applying a modulation signal to the driving electrode, in which the modulation signal has a current amplitude defined by a first current value and a second current value that is greater than the first current value. The modulation signal is in a negative gradient region in which the internal resistance decreases in contrast to the increase of the current.
