Title: Numerical analysis device by discrete nabla operator and non-storage type coefficient matrix
Inventor: TANAHASHI TAKAHIKO
IPC: G06F17/13
Filed: 2001-04-27
Abstract: PROBLEM TO BE SOLVED: To attain a high-speed calculation while maintaining precision of calculation with a small storage capacity in a numerical analysis device which utilizes a finite volume method or a finite element method of a non-structured grating. SOLUTION: A discrete nabla operator is defined, taking note of the fact that a nabla operator is a vector volume and is a volume not dependent on a coordinate system. A coefficient matrix element described by the discrete nabla operator is disintegrated into the product of a part dependent on a shape of the element and a part not dependent on a shape of the element. Only the part dependent on a shape of the element is stored while the other part is found analytically. Each time a need arises in matrix calculation, the coefficient matrix element is created from this. When this discrete nabla operator is used in the finite volume method or the finite element method of a non-structured grating, a non-storage type coefficient matrix can be created.  Therefore, the coefficient matrix can be found without having to store all the coefficient matrix elements, thus offering low-capacity storage unit and high speed calculation.

Title: Microresonator for light-to-light switch and light-to- light switch
Inventor: SASAKI FUMIO
IPC: G02F1/35
Filed: 2001-05-01
Abstract: PROBLEM TO BE SOLVED: To make an operating light low powered and the response time faster in a microresonator for light-to-light switch and an light-to-light switch. SOLUTION: Substances having a high polarizability or a combination of the substances and transparent bodies are regularly arranged in the microresonator for light-to-light switch in a way that a resonator mode having an absorption band is present therein. When a signal light is incident upon without the incidence of a control light, the energy level only by the signal light is not more than the transmission threshold value of the resonator, thus the signal light is not transmitted. When the signal light is incident upon with the incidence of the control light, the signal light is excited by the control light and the energy level thereof is made to be not lower than the transmission threshold value of the resonator, so that the signal light is transmitted.  The control light excites the specified signal mode of the resonator or the waveguide mode thereof, thus enabling the action of the switch to be lower powered. By setting the specified mode to the side, having sufficiently low energy, of the absorption band, it is realized that the response time is made to be faster and that the thermal effects are reduced.
