    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 has a microphone, an analog to digital converting circuit, a semiconductor memory, an input device, and a controller. The analog to digital converting circuit converts an output signal from the microphone into a digital signal. The semiconductor memory stores the digital signal. The input device at least carries out input of a record start instruction and a record end instruction. The controller, according to the instruction input from the input device, controls the start and stop of writing the digital signal into the semiconductor memory. When the input device is operated and a predetermined time interval has passed, the controller controls to start writing the digital signal from the analog/digital converting circuit into the semiconductor memory.
