摘要： In an optical amplification characteristics simulation apparatus according to the present invention, using spectrums of a signal light input to an optical amplifier and a characteristic parameter for amplification medium, gain wavelength characteristics of the amplification medium are calculated. A calculating formula for the above has a parameter corresponding to a gain fluctuation portion due to a gain spectral hole burning (GSHB) phenomenon, and this parameter is defined by a function obtained by modeling a physical phenomenon in which a population inversion rate is reduced due to the GSHB, based on that electron occupation numbers in each Stark level on the end level side are increased. Then, based on the calculated gain wavelength characteristics, the output power of the signal light is obtained, to thereby perform the optical amplification characteristics simulation on the optical amplifier. As a result, it is possible to construct a high versatile calculation model based on the physical phenomenon for the gain fluctuation due to the GSHB, to thereby simulate with high precision the optical amplification characteristics of the optical amplifier under arbitrary conditions.

摘要： Phosphor 8 is attached to window portion 6 of housing vessel 7 in light-emitting diode 20. Blue excitation light 9 emitted from blue light-emitting diode chip 4 is irradiated on phosphor 8, and part of excitation light 9 is absorbed by phosphor 8, which converts its wavelength and produces yellow fluorescence 9a to be emitted outward from light-emitting diode 20. In addition, part of excitation light 9 also passes through phosphor 8 and becomes transmitted excitation light 9b, which is then emitted outward from light-emitting diode 20. Yellow fluorescence 9a and blue transmitted excitation light 9b blend to become white light 10.
