Abstract

Exemplary embodiments of an apparatus, method, and computer readable medium are provided for producing a radiation. For example, a radiation having at least one pulse with a pulse-width of less than approximately 30 picoseconds can be produced using a photonic crystal waveguide arrangement which is (i) specifically structured and sized so as to be placed on an integrated circuit, and (ii) configured to produce the radiation having at least one pulse with a pulse-width of less than approximately 30 picoseconds.

Claims (33)
