Abstract

Delivery of microwave signals on optical carriers is a promising evolution of microwave networks [1]. In addition, optical generation of high-frequency signals (hundred of GHz up to several THz) is interesting for many applications from far infrared spectroscopy to optical communications where a frequency multiple of 20-GHz is a standard of utmost interest. A way to generate microwave and THz-signals is to use the beat-note of two cw signals [2], usually from a dual wavelength laser [3]. In this paper we describe a promising technique to generate microwave and THz signals that joins the high-temporal coherence of a solid-state laser with the simplicity of tuning of a fiber Bragg grating (FBG).
