摘要： There is provided a semiconductor optical modulator capable of performing a stable operation and having an excellent voltage-current characteristic to an electric field while exhibiting the characteristic of a semiconductor optical modulator with an n-i-n structure. The semiconductor optical modulator includes a waveguide structure that is formed by sequentially growing an n-type InP clad layer (11), a semiconductor core layer (13) having an electro-optic effect, a p-InAlAs layer (15), and an n-type InP clad layer (16). An electron affinity of the p-InAlAs layer (15) is smaller than an electron affinity of the n-type InP clad layer (16). In the waveguide structure having such a configuration, a non-dope InP clad layer (12) and a non-dope InP clad layer (14) may be respectively provided between the n-type InP clad layer (11) and the semiconductor core layer (13), and between the semiconductor core layer (13) and the p-InAlAs layer (15).

摘要： An apparatus for converting character data into audio data form includes a storage unit for storing the character data supplied, an operating unit manipulated by the user, and a control unit responsive to the entry of command from the operating unit for producing indicator data indicative of unwanted portions of the character data which are not required for conversion to audio data, comparing the indicator data with the character data read out from the storage unit, and converting the portion of the character data not corresponding to the indicator data into its audio data form. As the character data read out from the storage unit has been compared with the indicator data not indicative of the unwanted portions of the character data required for conversion to audio data, its dedicated portion not corresponding to the indicator data is converted into its audio data form. This allows the dedicated portion of the character data to be readily converted into its audio data form while aborting the unwanted portions of the character data, thus enabling quick acquisition of the information.
