摘要： A molecular modeling system and a molecular modeling method comprsing a molecular dynamics (MD) tool using a new potential related to a heterogeneous intermolecular interaction, a molecular modeling (MM) tool carrying out a new fast self-regulating optimization, a new molecular potential generator (MPG) tool, and a molecular modeling expert database tool in order to solve the problems concerning specified intermolecular interactions in modeling homogeneous and heterogeneous intermolecular interactions, such that the accuracy of the potential functional is poor and that either the potential function or the potential parameter is unknown. The above system and method serve to solve the problem that a parameter related to the functional of a specified interaction is unknown, the problem that the cost of calculation for the optimization of a new potential functional is high, and the problem of selection of an initial value of optimization procedures.

摘要： Optical signal communication equipment and optical communication system which can be suitably used even when the transmitting speed and capacity of information transmitted by using optical signals are increased. On the optical signal transmitting side, signal light is generated by causing induced emission in an active medium by supplying exciting light to the medium in accordance with transmitting signals. The exciting light is supplied to the active medium in such a way that naturally emitted light is made incident to a semiconductor layer and the component of the light having a specific wavelength is Bragg-reflected by modulating the refractive index of the semiconductor layer by impressing the voltage pulse correspdoning to the transmitting information upon the semiconductor layer, and then, the reflected light is supplied to the medium as the exciting light. Since the Bragg reflection and associated induced emission show excellent responsiveness to voltage signals having pulses widths of 1x10 second on shorter, an optical communication system which can transmit optical signals at a transmitting speed of up to 100 Gb/s can be realized.
