Laser interferometry serves a fundamental role in science and technology, assisting precision metrology dimensional length measurement. During the past decade, laser frequency combs---a coherent optical-microwave ruler over broad spectral range with traceability to time-frequency standards---have contributed pivotal roles ever-growing demands measurement precision. Here we report spectrally res...

It was recently pointed out that the spectral fluctuations of quantum systems are formally analogous to discrete time series, and therefore their structure can be characterized by the power spectrum of the signal. Moreover, it is found that the power spectrum of chaotic spectra displays a 1/f behavior, while that of regular systems follows a 1/f2 law. This analogy provides a link between the co...

Mostly forsaken, but revived after the emergence of all-dielectric nanophotonics, Kerker effect can be observed in a variety nanostructures from high-index constituents with strong electric and magnetic Mie resonances. A necessary requirement for existence response limits use generally nonmagnetic conventional plasmonic effect. In spite this, we demonstrate here lattice regular Al nanostructure...

We design, fabricate and characterize a CMOS-compatible, Mach-Zehnder-coupled, second-order-microring-resonator filter with large Free Spectral Range and demonstrate non-blocking thermo-optical filter reconfiguration. The device consists of 10-μm radius silicon microring resonators, with an FSR equivalent to that of a structure consisting of 5-μm radii microrings. The structure is reconfigurabl...

Tunable laser radiation with megahertz linewidth is generated with a simple, inexpensive, and compact laser system that uses two common microscope slides as the only intracavity tuning elements. The laser emits two radiation modes whose frequencies are separated by 1.2 GHz, corresponding to the free spectral range of the laser resonator. The frequencies may be rapidly varied over a range of 1.5...
