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： 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.

摘要： Prepared is an n− type semiconductor substrate 1 having a first principal surface 1a and a second principal surface 1b opposed to each other, and having a p+ type semiconductor region 3 formed on the first principal surface 1a side. At least a region opposed to the p+ type semiconductor region 3 in the second principal surface 1b of the n− type semiconductor substrate 1 is irradiated with a pulsed laser beam to form an irregular asperity 10. After formation of the irregular asperity 10, an accumulation layer 11 with an impurity concentration higher than that of the n− type semiconductor substrate 1 is formed on the second principal surface 1b side of the n type semiconductor substrate 1. After formation of the accumulation layer 11, the n− type semiconductor substrate 1 is subjected to a thermal treatment.

摘要： A fixing device includes a fixing unit and a switching unit. The fixing unit includes an emitting unit that emits light and a housing that houses the emitting unit. The fixing unit fixes a toner image to a recording medium by emitting the light to a surface of the recording medium, the recording medium having the toner image formed thereon and having been transported to a predetermined fixing position that is away from the housing. The switching unit switches a state of the fixing device from a first state in which the housing and the recording medium are positioned away from each other to a second state in which the surface of the recording medium at the fixing position is sealed with the housing.
