We have developed the high-speed PLZT ((Pb,La)(Zr,Ti) O 3) optical content distribution system having slot-switch and GMPLS controller in the 1X8 distribution switch. The switching speed of our developed system is less than 10 nsec and the world fastest switching time in the optical switch with more than 8 outputs. The system can switch transparent time(More)
We design and implement an optical slot switching network for bulk content transfer. To realize the slot switching network, we employ the generalized multiprotocol label switching (GMPLS) extension protocol to reserve and release slots dynamically according to the application. We use optical switches as relay points in the slot switching network, and we(More)
We demonstrate optical fiber-delay-line buffers with 1times8 PLZT optical switches and a parallel pipeline buffer manager. Error-free buffering (bit-error-rate &lt;10<sup>-9</sup>) has been achieved for 640 (64-wavelength times 10) Gbit/s wide-colored optical packets.
