    Abstract: An optical device includes an optical grating coupler and a plurality of optical waveguides coupled thereto. The optical grating coupler is formed along a planar surface of a substrate, and includes a pattern formed by ridges concentrically located on the surface about a center thereon. Each adjacent pair of ridges is separated by a groove. Each waveguide of the plurality of waveguides is oriented about radially with respect to the center, and has a first end that terminates near an outermost one of the ridges. The first ends are about uniformly spaced along the outermost one of the ridges.

    Abstract: A polarization-diverse optical amplifier includes a polarization-sensitive optically active medium and a polarization splitter. The polarization splitter is configured to receive input light, to direct a first polarization component of the received input light to a first optical path segment, and to direct a second polarization component of the received input light to a separate second optical path segment. The active medium has first and second optical ports. The first optical port is at an end of the first optical path segment. The second port is at an end of the second optical path segment. The active medium outputs amplified light from one of the ports in response to receiving the input light at the other of the ports. In a preferred embodiment, the active medium has an internal optical axis, and the polarizations of the first and second components are oriented relative to that axis so that amplification is enhanced. The two optical path segments may include polarization-maintaining optical waveguides.

    Abstract: A mode-locked laser that has an optical cavity containing multiple optical amplifiers, each dedicated to a respective spectral portion of an optical signal generated by the laser, wherein the dispersion effects are managed by utilizing a separate intra-cavity phase tuner for each such spectral portion and/or by having appropriately configured waveguides corresponding to different spectral portions. Advantageously, a relatively wide combined gain spectrum provided by the optical amplifiers and the intra-cavity dispersion compensation provided by the phase tuners and/or waveguides enable this laser to realize a mode-locking regime that results in the emission of an optical pulse train having a relatively wide frequency spectrum. In one embodiment, the optical cavity of the mode-locked laser has a perfectly spectrally sampled arrayed waveguide grating (AWG) that is configured to divide the optical signal into the spectral portions and apply these portions to the respective waveguides, optical amplifiers, and phase tuners.
