摘要： At least a one conductivity type nanostructure PS layer whose thickness is controlled, and the opposite conductivity type nanostructure PS layer and a one conductivity type mesostructure PS layer arranged in contact with both these sides are comprised. Since the one conductivity type nanostructure PS layer is formed by anodizing the non-degenerate n-type crystalline silicon layer whose thickness is established in advance, the thickness which can provides a maximum luminescence efficiency can be obtained correctly. Then a semiconductor light emitting device whose luminescence efficiency is improved without increasing an unnecessary series resistance is provided. An inexpensive semiconductor light emitting device having a large light emitting area can be provided, since silicon wafer having a large diameter can be employed as the material for light emission.

摘要： An optical logic element is disclosed which performs an XOR operation through utilization of the high-speed property of light. On each branched waveguide of a Mach-Zehnder interference type optical waveguide there is provided a phase modulating element whose refractive index undergoes a change when it is irradiated by light. The interference type optical waveguide is adapted to provide different optical output levels when the refractive index changes of the phase modulating elements are both zero or a predetermined value and when they differ from each other. Thus, the optical logic element is capable of performing the XOR or XNOR operation at an ultrahigh speed.

摘要： In a Raman gain measuring method according to the invention, a CW (continuous wave) probe light is input into a Raman amplifying medium. A Raman pumping light being binary-intensity-modulated at a modulation factor is generated. The Raman pumping light is input into the Raman amplifying medium. Two index values regarding to AC component and DC component are extracted from the probe light having propagated through the Raman amplifying medium. The Raman gain of the Raman amplifying medium is determined from the two index values and the modulation factor.
