Original Abstract Submitted

in absence of electrical approaches for realization of highly stable rf oscillator, opto-electronic oscillators (oeo) techniques are provided, where self-forced oscillation techniques using long optical delays demonstrate significant short-term and long-term frequency stability. fully integrated opto-electronic oscillator chip (ioec) may be the most efficient realization of an rf frequency synthesizer in terms of operation frequency (covering microwave and millimeter wave), size (<10 cm), ruggedness to environmental effects of temperature (−40 to 80c), vibration (up to 40), low timing jitter (<5for 40 ghz carrier), and wall-plug efficiency (output power >10 dbm from under 1 w power). a free-running iii-v (primarily inp) based multi-mode laser (mml) diodes is designed with large mode number (e.g., over 60 modes) and intermodal oscillation frequency compatible with desired rf carrier signal (e.g., 1-40 ghz).
