Implementation of High-GHz-to-THz Optical Data Links

Recent research has demonstrated a number of new optical processes based on the interaction of temporally structured light beams with spectrally-selective recording materials. One of these all-optical processes provides for the ultrahigh speed, temporal-waveform-controlled, spatial routing of optical beams (time-to-space conversion). Propagation of an optical data stream through an entirely passive time-to-space-optical-converter device leads to the generation of spatially distinct optical signals marking the passage of specific temporal data segments. Triggering data segments are defined in device preprogramming. A variety of functions vital to the realization of ultrahigh bandwidth communications systems (operating at single-channel rates of up to 1 Tbit/sec) can be provided by devices based on time-to-space conversion. Templex Technology Corp. proposes a Phase I SBIR effort intended to evaluate performance levels achievable with time-to-space conversion devices implemented on short time scales with currently available support technologies and materials. As part of this plan, two prototype devices will be designed and expected performance characteristics analyzed. This Phase I effort lays the groundwork for a dynamic Phase II effort involving a cycle of device fabrication, characterization, and redisign aimed a the development of an entirely new class of commercial devices useful in the implementation of ultrahigh bandwidth communication systems.
