摘要： An optical wiring substrate provides a slab optical waveguide having a refractive index different from a refractive index of other surrounding portions and a planar convex lens being provided continuously to a tip portion of an optical path of an optical wave guide including a core and cladding and formed on a substrate. The optical path of light passing through the planar convex lens is converted approximately by 90° with a mirror. The light reflected with the mirror is made as parallel light rays by use of a cylindrical lens.

摘要： An optical transmission system in which influences of worsening of the waveform by SPM are canceled by setting an amount of compensation of a dispersion compensator at about 50% of a total amount of dispersion of an optical fiber transmission line so that received waveform is almost not varied, even if light intensity is varied. In the case where a plurality of dispersion compensators are used, the number of compensators is optimized by setting arrangement interval in the neighborhood of a receiving end at a small value. Further, in a transmission line, in which amounts of dispersion of optical fibers have positive and negative fluctuations, the smallest transmission distance of a transmission system is increased by effecting dispersion compensation so that an expected value of the total amount of dispersion of the transmission line is abnormal dispersion.

摘要： In an optical transmission system, SPM influences on the degradation of wave forms are canceled by setting an amount of compensation of a dispersion compensator at about 50% of the total amount of dispersion of an optical fiber transmission line so that a received wave form is substantially not varied, even if light intensity is varied. When a plurality of dispersion compensator are used, the number of compensators is optimized by setting the arrangement interval in the vicinity of the receiving end to a small value. Further, in a transmission line, in which amounts of dispersion of optical fibers have positive and negative fluctuations, the smallest transmission distance of a transmission system is increased by effecting dispersion compensation so that an expected value of the total amount of dispersion of the transmission line is abnormal dispersion.

摘要： An optical frequency division multiplexing transmission system for sending a large volume of information by a single optical fiber is disclosed. Each of an optical frequency division multiplexing transmitter equipment and an optical frequency division multiplexing receiver equipment has an optical filter having a periodic optical transmission characteristic therein. Each optical filter is stabilized with an absolutely-stabilized standard optical frequency. Each optical signal frequency is stabilized to a periodic transmission characteristic of the optical filter arranged in the optical frequency division multiplexing transmitter equipment, and each local frequency to a periodic transmission characteristic of the optical filter arranged in the optical frequency division multiplexing receiver equipment. Even in the case where no optical signal is applied to the optical frequency division multiplexing receiver equipment due to such causes as a fault of the transmission optical source or the breakage of an optical fiber, the local optical source frequency continues to be controlled in stable fashion.
