Final Report on Contract N00014-85-C-0078 (IBM Thomas J. Watson Research Center).

摘要

The attached series of reprints dating from 1985 through 1990 details the work performed with partial support from ONR under the subject contract. In particular, via coherent effects, polarization beats were observed and the optical phase of a frequency swept pulse was measured. Using two stage pulse compression, 16 fsec, frequency tunable optical pulses were produced. New methods were introduced to reduce the wings on compressed pulses and the worlds fastest light-driven optical modulator was demonstrated. The first measurement and detailed analysis of dark pulse solitons in fibers were performed. An optical shock wave and wave-breaking were observed in the nonlinear propagation through single-mode optical fiber. A new standard in optoelectronic performance was set with our generation and detection of subpsec electrical pulses. Subsequently, electronic shock waves were produced on coplanar transmission lines and the observations were compared in detail with theory. This work culminated in the development and application of an optoelectronic THz system. This system has been fully characterized and used to perform THz spectroscopic measurements on important electronic materials.
