Title: Optical nonlinear element
Inventor: TOKUDA YASUKI
IPC: G02F1/017
Filed: 1988-09-22
Abstract: PURPOSE:To vary the absorption characteristics according to the wavelength of signal light by flattening the bend of the energy band in a light absorption region by the carrier formed by incidence of the signal light. CONSTITUTION:A quantum well layer 25 of 100Angstrom  and a quantum well layer 26 of 80Angstrom  are laminated via a tunnel barrier layer 27 to constitute an asymmetric bond quantum well structure. The band structure is bent in the thermally equil. state because of the built-in electric field and is flattened because of screening by photoexcitation carriers when the intensity of the incident light is gradually increased. Since the carriers generated by the photoexcitation in such a manner negate the built-in electric field made in a p-i-n junction, the energy band is nearly flattened and the quantum levels are intersected at this time, by which the absorption peak wavelength is changed. The absorption characteristics are varied in this way according to the wavelength.

IPC: G08B13/22
Filed: 1988-09-24
Abstract: PURPOSE:To obtain a warning system, which is hardly noticed by an unfair invader, by generating wraning with corresponding to the rapid change of an electric characteristic in a detected plant. CONSTITUTION:When the unfair invader approaches a plant 14, in which detecting electrodes 12a and 12b are buried, the vital current of the plant 14 flows between the detecting electrodes 12a and 12b (changes). By the flow of the vital current, the current of fixed strength is outputted from the output edge of an amplifying device 16 and in correspondence to the output of the current, a tone is generated from a sound source device 18. Thus, since a device such as a light emitting device or a photo-detecting device to be easily discovered by the unfair invader is not used, the warning system to be hardly noticed by the unfair invader can be obtained.
