Description

[0001] Priority claims and cross-references to related applications [0002] This patent document claims priority to US Patent Provisional Application No. 61 / 500,542, entitled "Parametric Regenerative Oscillator" and filed June 23, 2011. All the disclosures of the above patent documents are incorporated by reference as a part of the disclosure of this document. Background technique [0003] This application relates to signal oscillators based on photonic devices. [0004] Radio frequency (RF) and microwave oscillators for generating RF and microwave frequency signals are widely used in applications involving electrical circuits, communication devices, and others. Using electronics and optics, such RF and microwave oscillators can be configured as "hybrid" devices to form optoelectronic oscillators ("OEOs" for short). See, eg, US Patent Nos. 5,723,856, 5,777,778, 5,929,430, and 6,567,436. [0005] For example, such an OEO may comprise an electrically controlled optical modul...

Problems solved by technology

This photoelectric loop is an active, non-inverting loop that oscillates the device under certain stable operating conditions or states, while the traditional loop stabilizes the device, so the photoelectric loop is different from the traditional feedback loop different roads
