    摘要： An optical pulse code recognition device and an optical distributor recognize multiple bits of a 1 Tbps packet signal as they are, all at one time. A serial signal light emitted from an optical fiber is collimated by a lens and applied onto a mask having a mask pattern. A thin film optical switch increases its optical transmittance when irradiated with a control light, allowing the collimated signal light to transmit through it. When the control light is applied, the transmitted collimated signal light is converted into a parallel signal. The mask pattern has multiple transmission portions allowing one bit of signal light to transmit through and an equal number of non-transmitting portions to block the light, and whether or not a bit pattern of the signal light and the mask pattern match each other is found by detecting a maximum or minimum value of light intensity with a photodetector.

    摘要： An optical switching device including a substrate and at least an organic film as a light control part formed on the substrate. Optical switching is performed by applying signal light and control light to the organic film, the wavelengths of the signal light and the control light being set in a region in the vicinity of resonance on the longer wavelength side in the absorption spectrum of the organic film; and by changing a real part or real and imaginary parts of the refractive index of the light control part by using the control light, to thereby cause a phase difference in the signal light.
