High-Performance Opto-Electronic Oscillator for Millimeter Wave
Agency / Branch:
DOC / NIST
Leveraging Agiltron¿s recent breakthrough in the broad band and tunable photonic high-Q factor RF filtering technique, we propose to develop a high-spectral-purity, low-phase-noise, spurs-free opto-electronic oscillator (OEO) operating at W-band for the NIST applications. Based on our unique technical approach and successful development in low loss fiber optics, RF photonic components/modules, and the drastic improvement in cost and performance of commercial electro-optical components, this OEO will provide a millimeter-wavelength source with ultra-high purity signal at 90 GHz to 110 GHz at room temperature. This RF source is a highly tunable module with high speed. The practicality of such an OEO scheme including photonic high-Q tunable RF filter in X-band operation has been demonstrated by Agiltron. In Phase I, the numerical simulation and the experimental evaluation of primary performance in the proposed novel scheme will be performed to design a full functioning OEO which will be implemented in the Phase II program. The performance and the cost of the source will be analyzed as well. Success in this program will significantly reduce mission cost, size and increase performance and utility of future telecommunication and radar sensor systems of commercial and military applications.
