    摘要: A semiconductor device including a buffer layer 32 on n-GaAs, a clad layer 31, a wave guide layer 30 and a carrier block layer 29 of n-AlGaAs, a side barrier layer 28 of non-doped AlGaAs, an active layer 27 which is formed by two non-doped GaAs quantum well layers and a barrier layer of AlGaAs, a side barrier layer 26 of non-doped AlGaAs, a carrier block layer 25, a wave guide layer 23 and a clad layer 22 of p-AlGaAs, and a cap layer 21 of p-GaAs are grown in this order. Inside the wave guide layer 23, current blocking layers 24 having a lower refractive index and higher Al-composition than that of the wave guide layer and sandwich a strip-shaped active region 34. This creates a refractive index difference between the active region 34 and buried regions 33 in which each of the current blocking layers 24 exists, thereby forming a refractive index guide structure. Thus, it is possible to obtain a high-output semiconductor laser device of the refractive index guided type which is easy to manufacture.

    摘要: The present invention relates to an information processing unit, an information processing method, and a program that can allow two-class classification to be correctly performed based on the outputs from two or more classifiers.The classifier 21i (i=1 to n) substitutes an input vector x into a classification function fi (x) to output a scalar value yi. The mapper 22i substitutes the scalar value yi provided from the classifier 21i into a mapping function gi(yi) found through a learning process described later to convert the scalar value yi from the classifier 21i to a class existence probability pi. The comparator 23 compares the class existence probabilities p1 to pn provided from the mapper 221 to 22n, respectively, with a predetermined threshold to classify which of two classes the input data belongs to, and outputs the classification result in the form of value “1” or “−1” The invention can be applied to, for example, an information processing unit for performing two-class classification.
