摘要： An optical device having a material exhibits an optical rectification effect is disclosed. The optical device utilizes direct current polarization which is induced in the material by a control light. The induction of the direct current polarization in the material by the control light changes the refractive index and absorption spectrum of the material. This is based on the so-called electrooptic effect and Franz-Keldysh effect. The present invention provides the optical device according to which external incident light can be modulated at high speed with the control light by utilizing the change of the refractive index or the change of the absorption spectrum.

摘要： A multi-quantum well structure which is formed by laminating thin semiconductor layers is provided with means for injecting carriers in a direction which is parallel to the surface of the laminated thin semiconductor layers, whereby it is possible to obtain satisfactory changes in refractive index of the carrier injection portion. For example, if the total reflection region of an optical switch consisting of optical waveguides which cross each other is provided with a multi-quantum well structure wherein carriers are injected in a direction parallel to the surface of the well, the extinction ratio characteristics of the device can be improved.

摘要： An optical device and an optical integrated circuit which incorporate an optical switch and have a novel function. Light sources are respectively coupled to two input ends of an X-type 2.times.2 optical switch, and light receivers are respectively coupled to two output ends of the optical switch, thereby obtaining an optical device which is capable of performing both AND and OR logics. A light source is coupled to one input end of an optical switch, and a light receiver is provided at one output end from which the light emitted from the light source emerges when no electric power is supplied to the optical switch, whereby it is possible to construct a system in which, even when one terminal has a power failure, there is no hindrance to other terminals. If an optical switch is arranged such as to use driving electric power as a modulating signal, the optical switch can serve as a modulator in which the output from one output end can be employed to monitor a modulated optical signal. In addition, if the optical switch is formed into, e.g., a carrier injection type optical switch using a semiconductor, the above-described devices can be fabricated as integrated circuit.

摘要： It is possible to narrow the emission spectrum linewidth of a semiconductor laser device by coupling optically an external resonator with one end surface of the semiconductor laser. However, the structure of the external resonator should match the phase of the light emitted by the laser. Heretofore, this matching has been effected by adjusting the length of the external resonator, and hence productivity and reproducibility have not been good. According to this invention, characteristics of the external resonator can be adjusted electrically to be matched with the phase of the emitted light owing to the fact that the external resonator is made of a material, whose refractive index can be varied electrically. Therefore the semiconductor laser device according to this invention is very practical.
摘要翻译：通过将外部谐振器与半导体激光器的一个端面光学耦合，可以缩小半导体激光器件的发射光谱线宽。然而，外部谐振器的结构应与激光发射的光的相位相匹配。迄今为止，这种匹配是通过调节外部谐振器的长度而实现的，因此生产率和再现性不好。根据本发明，外部谐振器的特性可以被电调节以与发射光的相位匹配，这是由于外部谐振器由折射率可以变化的材料制成。因此，根据本发明的半导体激光器件非常实用。

摘要： A medium-scale IP telecommunications network is configured in a low-cost optical network with good reliability and expandability. A physical configuration example has a center node 2-1 and eight local nodes 2-11 through 2-18 connected in one OADM ring 2-21/2-22. The logical configuration is a star configuration with the central node 2-1 at its origin with all traffic passing through the center node 2-1. The local nodes 2-11 through 2-18 are connected to the central node 2-1 by wavelength-unit optical channels or optical paths λ1 through λ8. Channels are added as required. Initially, for example, the center node 2-1 and the local node 2-5 are connected by λ5, but λ13 can added when the need arises. Since the logical star network is limited to approximately two add/drop optical channels at local nodes, costs are reduced by using inexpensive filters (e.g., dielectric interference film filters or fiber Bragg reflectors) that are capable of extracting only the specific wavelength of the optical channel. High reliability is provided through the use of optical switches for correction of fiber transmission path failures.
摘要翻译：中等规模的IP电信网络配置在低成本的光网络中，具有良好的可靠性和可扩展性。物理配置示例具有连接在一个OADM环2-21/2-22中的中心节点2-1和8个本地节点2-11至2-18。逻辑配置是一个星型配置，其中心节点2-1位于其原点，所有业务通过中心节点2 - 1。局部节点2至11至2-18通过波长单位光学信道或光学路径λ1至λ8连接到中心节点2-1。根据需要添加渠道。最初，例如，中心节点2-1和本地节点2-5通过λ5连接，但是当需要时可以添加lambda 13。由于逻辑星形网络在局部节点处限制在大约两个加/减光通道，所以通过使用廉价的滤波器（例如，介质干涉膜滤波器或光纤布拉格反射器），能够仅提取光学特定波长的成本降低渠道。通过使用光学开关提供光纤传输路径故障的高可靠性。

摘要： First feedforward calculation is executed when a preprocessing surface profile is measured and a processing chamber with its processing parameter value having been obtained through the first feedforward calculation judged to be within an allowable range is determined. Wafer transfer is executed only in conjunction with a processing chamber having a processing parameter value judged to be within the allowable range, and the wafer is carried to the entry point of the processing chamber. Then, second feedforward calculation is executed by reflecting the results of feedback calculation executed based upon the most recent processing having been executed in the particular processing chamber and wafer processing is executed in the processing chamber based upon the processing parameter value calculated in the second feedforward calculation.
