Terahertz Bandwidth Optical Sampling

摘要

Characterization of short optical pulses, such as occur in high speed optical communication systems, is currently performed usign electronic instrumentation of limited bandwidth. The current state-of-the-art fast detector and oscilloscope combination can achieve a bandwidth of roughly 50 GHz with an impulse response of roughly 10 ps. Optical sampling offers the capability to extend this bandwidth into the terahertz range.
