OPTICAL SWITCHING SYSTEM FOR OPTICAL WAVELENGTH-DIVISION AND TIME-DIVISION MULTIPLEXED SIGNALS |
摘要 |
An optical switching system for optical wavelength-division and time-division multiplexed signals includes a plurality of tunable wavelength filters each of which selects a signal having a desired wavelength from an optical wavelengthdivision and time-division multiplexed signal, a plurality of optical memory elements each of which is supplied with an output signal of each of the plurality of tunable wavelength filters. each optical memory element memorizes a light intensity of the output signal by being applied with a first control voltage and supplies an output port with the output signal which is converted to have a predetermined wavelength in a desired time slot. The tunable wavelength filters and optical memory elements may by replaced by wavelength filters and tunable wavelength optical memories.
