We report a time-to-space conversion technique using a material which has a large χ[sup (3)](=10[sup -6] esu) and a fast response time (<7 ps) at room temperature. The material is a self-organized quantum-well system consisting of inorganic well layers and organic barrier layers. We achieve a high conversion sensitivity even for nJ-order optical pulses. We demonstrate serial-to-parallel conversion of nJ-order Tbits/s signals at room temperature with conversion rates of 140 GHz. © 2000 American Institute of Physics.

    Conformal space-time symmetries of electromagnetic fields and potentials are studied in order to determine whole sets of constants of motion when spin- 1/2 charged particles interact with such external electromagnetic fields. The relativistic and nonrelativistic contexts are discussed through...

    A new proof of the generalized Birkhoff theorem in general relativity is presented. The partial results contained in previous proofs are recovered in a unified treatment of the different kinds of space-times to which the theorem applies. The proof is based on the fact that these space-times are...
