Title
Microwave generation and transmission using optical heterodyning or optical upconversion technique
Abstract
Two optical/microwave generation techniques are discussed. 140 Mbit/s transmissions with optically generated microwaves at frequencies at of 18 and 60-70 GHz are reported. Quartz accuracy and sub-Hertz linewidths of an optical microwave generator signal are demonstrated.
