Abstract: PURPOSE:To reproduce a desired optical pulse signal train information from an optical pulse train that undergone the time division multiplex modulation in a picosecond time area. CONSTITUTION:Each signal data pulse train is reproduced in real time from an optical data pulse train 21 that undergone the time division multiplexing. The train 21 is spatially increased, and also the wave head is tilted. A probe pulse 25 is also spatially increased. Both optical data and probe pulses are made incident on a medium 27 having the double photon absorbing effect so that these pulses cross spatially to each other. Then the output light that received the nonlinear transmission factor dependent on the time overlapping state of both data and probe pulses undergone the time division multiplexing is detected as the information on a spatial pattern.

SOLUTION: A substrate for forming an electron source defines an electron emission device on a second layer 7. A first layer 6 having SiO2 set to the major component is provided mainly for blocking the diffusion of Na to a member constituting the electron emission device and has an effect of suppressing the Na diffusion from the substrate 1 by formed on the substrate 1 containing Na. A second layer 7 contains electron conductive oxide and is provided to prevent the electrification of the substrate surface where the electron emission device is formed. The second layer 7 has the electron conductivity to suppress the charge-up of the substrate surface so that the electron emission device arranged on the second layer 7 obtains stable electron emission characteristics.

Abstract: PURPOSE:To provide an optical data pulse train generating method which can generate the optical data pulse trains at a super-high speed and with no limitation by an electrical modulation speed. CONSTITUTION:An optical pulse 6 passes through a beam splitter 1 and is divided into plural diffracted beams by a diffraction grating 2. Then the diffracted beams are turned into the one-dimensional perallel beams by a collimator lens 3 and then made incident on a space modulator 4. The modulator 4 is divided into plural segments according to the number of information bits. Then only the transmitted beams reach a reflector 5 among those beams that are transmitted (bit 1) or cut off (bit 0) by the modulator 4. These transmitted beams are reflected on a stepped reflecting surface end the optical path difference, i.e., the time delay is caused between the beams at a fixed interval. Then these beams are condensed on the same optical path by a collimator lens 3 via the modulator 4. These condenced beams have the time delays at the fixed intervals end therefore a time series pulse train 7 is generated.
