Optical frequency comb for communication band

Abstract

We introduce an optical frequency comb (OFC) generator based on an EO modulator installed in an optical cavity. The OFC generator has been employed for measurements of laser frequencies. For that purpose, the span of OFC was expanded to reach to 3OTHz around 1.5 μm by using self-phase modulation in an optical fiber. We propose here a method to generate a high power and flat spectrum of OFC. By this method a multi-wavelength light source for DWDM system can be generated from OFC generator.
