摘要： Improved optical modulation is provided in materials which are both piezoelectric and optically isotropic. This enables an acousto-optic modulator configuration with a longitudinal interaction geometry for the optical and acoustic waves which also provides a large acceptance angle. Preferably, the acoustic modulation is at a frequency that corresponds to a mechanical resonance of the modulator window.

摘要： A Q switch resonator includes: an optical resonator comprising at least two mirrors, and configured to accumulate power of a continuous wave or an intermittent continuous wave incident from an outside; and a switching element provided in the optical resonator. The switching element is configured such that, when the power accumulated in the optical resonator increases to a predetermined level, the switching element outputs an optical pulse by lowering a Q factor from a first level to a second level lower than the first level.

摘要： A proportion adjustable single-photon beam splitter based on cold atom storage includes a two-dimensional magneto-optical trap for receiving a first optical signal to be split; and a coupling beam. The coupling beam is incident at a certain angle with the first optical signal to the two-dimensional magneto-optical trap. The storage time of the two-dimensional magneto-optical trap 1 can be adjusted by controlling the switching time of the coupling beam, and then adjusting a proportion of a photon number of a storage part and a photon number of a leakage part of the first optical signal. A splitting proportion may also be adjusted by controlling an optical depth of the alkali metal atomic group trapped in the two-dimensional magneto-optical trap.

摘要： Acoustically mediated pulsed radiation sources, phased arrays incorporating the radiation sources, and methods of using the radiation sources and phased arrays to generate electromagnetic radiation via magnetic dipole emission are provided. The radiation sources are based on a superlattice heterostructure that supports in-phase magnetic dipole emission from a series of magnetic insulator layers disposed along the length of the heterostructure.

摘要： Apparatus and methods for fluorescence imaging using radiofrequency multiplexed excitation. One apparatus splits an excitation laser beam into two arms of a Mach-Zehnder interferometer. The light in the first beam is frequency shifted by an acousto-optic deflector, which is driven by a phase-engineered radiofrequency comb designed to minimize peak-to-average power ratio. This RF comb generates multiple deflected optical beams possessing a range of output angles and frequency shifts. The second beam is shifted in frequency using an acousto-optic frequency shifter. After combining at a second beam splitter, the two beams are focused to a line on the sample using a conventional laser scanning microscope lens system. The acousto-optic deflectors frequency-encode the simultaneous excitation of an entire row of pixels, which enables detection and de-multiplexing of fluorescence images using a single photomultiplier tube and digital phase-coherent signal recovery techniques.
