DIFFERENTIAL GROUP DELAY MODULES AID INSTANTANEOUS MICROWAVE MEASUREMENTS

摘要

Optoelectronic techniques applied to RF technologies is a growing trend, and with good reason. The benefits optoelectronics provide are immunity to electromagnetic interference and extremely wide bandwidth transmissions. Now, researchers Songnian Fu, Junqiang Zhou, Perry P. Shum, and Kenneth Lee of the Network Technology Research Centre and Temasek Laboratories of the Nanyang Technological University, Singapore, have demonstrated a photonic technique to create an adjustable microwave frequency measurement system.
