摘要： A laser source is configured for all-optical AM-FM up-conversion. In one exemplary embodiment, an amplitude modulated (AM) optical input signal containing a baseband signal at a sub-microwave frequency, is injected into the laser source. The amplitude of the AM optical input signal and the optical carrier frequency are adjusted so as to place the laser source in a period-one dynamical state characterized by a transitioning of the laser source from a free-running optical frequency to at least two optical frequencies having a separation distance equal to a period-one microwave frequency. As a result of the period-one dynamical state, a frequency modulated (FM) optical output signal containing the baseband signal carried at the period-one microwave frequency, is propagated out of the laser source. The period-one microwave frequency is operative as a sub-carrier signal.

摘要： Systems and methods that enhance the resolution of a microscope in all three spatial dimensions. A microscope system is provided that typically includes a first objective lens (20), an illumination source that provides excitation illumination (?ex) at a first wavelength through the objective lens (20) in a first direction onto a fluorescent sample so as to induce fluorescent emission in the sample at a second wavelength (?fI) different than the first wavelength. The system also typically includes an element (60) that provides illumination at the second wavelength (?fl) to the sample in a second direction different from the first direction, and a detector (10) for detecting the fluorescent emission. The optical gain of the fluorescent emission at the second wavelength is enhanced through stimulated emission.
