For ultra-high speed optical networks, generating high repetition rate pulse trains is difficult. Current technology provides integrated optical structures that are used to split one pulse into many, but with a large inherent loss that increases with splitting ratio. Therefore, improved methods for generating high repetition rate pulse sequences with a low inherent loss are needed.

Purdue University researchers have developed a novel system for generating ultra-high speed pulse sequences from a single, low repetition rate, short pulse laser. This system increases measurement sensitivity and reduces the optical power requirements while retaining sufficient optical bandwidth to avoid measurement distortion.

-Provides the ability to obtain very large pulse split ratios with very low loss
-Avoids synchronizing different short pulse sources
-Only a single short source pulse laser required
-500-fold increase in sensitivity
-Provides large optical bandwidth with unparalleled sensitivity

Potential Applications:
-High-speed lightwave test instrumentation
-Optical performance monitoring instrumentation
