Abstract

Free-space interconnections for optical computing and information processing require an understanding of the three dimensional propagation of ultrahigh bandwidth optical pulses. Unlike optical fibers that are basically waveguides, free space propagation involves additional phenomenon such as self-focusing. In order to understand the properties of unguided or free space propagation for interconnections it is necessary to use a three dimensional spatial grid as well as the usual temporal grid. We derived an expression for the propagation of free space optical pulses for data rates on the order of hundreds of terabits/sec. Our formulation incorporates physical parameters such as the pulse duration, pulse intensity and free space characteristics. Numerical calculations show the spatiotemporal pulse distortion for free space propagation.
