摘要： Provided is a diffraction grating having a surface with a groove-and-ridge structure formed with a preset periodic distance, the groove-and-ridge structure including a plurality of grooves, wherein a concave structure and/or a convex structure extending across at least one of the grooves and having a level difference from the bottom surface of the groove is formed on the surface. In the diffraction grating according to the present invention, the diffracting grooves in the groove-and-ridge structure formed with the preset periodic distance are divided into a plurality of sections. Therefore, even if oil or water contained in air-born dust, the sebum or perspiration of a user, or a similar liquid substance is adhered to the surface of the diffraction grating, the oil or the like will not spread over an area other than the section to which it has adhered. Thus, a decrease in the diffraction efficiency is prevented.

摘要： An arrangement is made such that the magnitude of cure shrinkage obtained by multiplying the thickness of a resin layer 2 between a master mold 1 and a negative mold substrate 3 by the cure shrinkage ratio of the resin and the magnitude of cure shrinkage obtained by multiplying the thickness of a resin layer 4 between the negative mold 23 and the surface of the spherical or flat substrate 5 by the cure shrinkage ratio of the resin can be compensated for by each other. In accordance with this method, an aspherical optical element having a higher precision than ever can be formed at reduced cost by a replica method involving the addition of a resin layer to the surface of a spherical or flat substrate.

摘要： Modulators respectively modulate baseband signals into IF signals having different frequencies. A multiplexer multiplexes the IF signals. An electrical-optical converter intensity modulates the multiplexed IF signals into optical signals. A local oscillation signal source outputs a predetermined local oscillation signal. An external modulator intensity-modulates the optical signal using the local oscillation signal. An optical branching portion branches the intensity-modulated optical signal and respectively outputs branched optical signals to radio base stations. An optical-electrical converter converts the optical signal into an electric signal, to obtain an RF signal by frequency-converting the IF signal. An antenna only transmits a component having a desired radio frequency extracted in a band filter from the RF signal to a subscriber terminal. Frequency conversion from the IF signal to the RF signal is thus optically performed, whereby the frequency or electrical-optical converter is shared among the radio base stations.
