All-optical wavelength and pulse-width conversions with a Sagnac interferometer semiconductor-based switch.

A Sagnac interferometer switch with a semiconductor optical amplifier is proposed for all-optical wavelength and pulse-width conversions. The configuration of this switch is simple, and the switching speed is not limited by the semiconductor carrier's recovery time. The pulse width of the input data, 1.5 ps, is converted to 2.4-18.1 ps. A wavelength conversion of input data at 1539 nm to a tunable-wavelength bandwidth of 15 nm (1550-1565 nm) is also demonstrated.

Photochemical ligation of DNA "words" for DNA computing.

The photochemical DNA computing of 5-vinyluracil ((V)U) containing oligodeoxynucleotides (ODNs) tethered multiple "DNA words" is demonstrated. A new MARK and UNMARK operation based on the (V)U mediated reversible DNA photoligation has been developed for multiple-word DNA computing. The utility of this operation for DNA computing is demonstrated by solving a small Satisfiability problem (SAT problem) in which information was encoded in three tandem words.
