An optically-efficient RF modulator

S.A. Havstad; Michael G. Wickham; Donald G. Heflinger; Paul Nachman; John C. Brock

Our RF modulator uses a novel arrangement of two low-biased Mach-Zehnder modulators within a ring laser, eliminating resonances and improving efficiency by over 7 dB relative to an externally modulated configuration. This will be useful for DC power-limited analog photonic links.
