    摘要： Examples of the present invention include integrated erbium-doped waveguide lasers designed for silicon photonic systems. In some examples, these lasers include laser cavities defined by distributed Bragg reflectors (DBRs) formed in silicon nitride-based waveguides. These DBRs may include grating features defined by wafer-scale immersion lithography, with an upper layer of erbium-doped aluminum oxide deposited as the final step in the fabrication process. The resulting inverted ridge-waveguide yields high optical intensity overlap with the active medium for both the 980 nm pump (89%) and 1.5 μm laser (87%) wavelengths with a pump-laser intensity overlap of over 93%. The output powers can be 5 mW or higher and show lasing at widely-spaced wavelengths within both the C- and L-bands of the erbium gain spectrum (1536, 1561 and 1596 nm).

    摘要： An optical device for splitting/combining a first and a second continuous optical wavelength bands, each wider than 10 nm, has a first, a second, a third, a fourth and a fifth optical splitting devices optically coupled in cascade and a first, a second, a third and a fourth optical differential delay devices optically coupled to, and interleaved between, the optical splitting devices. A suitable choice of the coupling angles of the splitting devices and of the differential delays of the optical differential delay devices gives to the structure flattened passbands and stopbands and makes the optical device tolerant to fluctuations of the structural parameters. An apparatus includes the optical device for use in fiber-to-the-premises networks.

    摘要： An add-filter device includes a plurality of ring resonators that are arranged to receive an optical signal of a specific wavelength and channel to be added onto a bus line that is arranged to receive a plurality of signals.

    摘要： An optical mode converter has a coupling waveguide and a receiving waveguide. The coupling waveguide has at an input end a first effective refractive index and includes a tapered core of a substantially constant refractive index with a substantially square cross section at the input end, which has a size that tapers down moving away from the input end. The coupling waveguide also has a cladding at least partially surrounding the tapered core. The receiving waveguide has a second effective refractive index at an output end and includes a core of a substantially constant refractive index greater than the refractive index of the tapered core of the coupling waveguide and a cladding at least partially surrounding the core. A side surface of the tapered core of the coupling waveguide is optically in contact, in a coupling portion, with the receiving waveguide so as to allow optical coupling between the coupling waveguide and the receiving waveguide. The refractive index of the tapered core of the coupling waveguide is selected so that the first effective refractive index and the second effective refractive index differ from each other in absolute value less than 30% of the difference between the core refractive index and the effective refractive index of the receiving waveguide.
