摘要： An arrayed waveguide grating includes an input/output waveguide 1, an input/output waveguide 2, a slab waveguide, an arrayed waveguide 1, a reflection zone 1, an arrayed waveguide 2, and a reflection zone 2. The input/output waveguide 1 and the input/output waveguide 2 are located on a same side of the slab waveguide, and are coupled to the slab waveguide. The reflection zone 1 is configured to reflect a light wave in a first band, and to transmit a light wave in a second band. The reflection zone 2 is configured to reflect the light wave in the second band. It is implemented that a single arrayed waveguide grating outputs light waves with different adjacent channel wavelength spacings, and a quantity of devices used in a system in which an uplink adjacent channel wavelength spacing and a downlink adjacent channel wavelength spacing are asymmetrical is further reduced.

摘要： An optical splitter has a main branch coupled to a number of tributary branches. The main branch includes a light-absorptive core and a light-reflective grating. The absorptive core can absorb light arriving from the tributary branches and transmit light arriving from the main branch to the reflective grating. The reflective grating can reflect light from the main branch back through the absorptive core to the main branch. Light arriving from the tributary branches exchanges mode with light reflected by the reflective grating.

摘要： An optical device includes an optical port array having first and second optical inputs for receiving optical beams and a first plurality of optical outputs associated with switching functionality and a second plurality of optical outputs associated with channel monitoring functionality. A dispersion element receives the optical beam from an input and spatially separates the beam into a plurality of wavelength components. The focusing element focuses the wavelength components. The optical path conversion system receives the plurality of wavelength components and selectively directs each one to a prescribed one of the optical ports. The photodetectors are each associated with one of the optical outputs in the second plurality of optical outputs and receive a wavelength component therefrom. The controller causes the optical path conversion system to simultaneously direct each of the wavelength components to a different one of the optical outputs of the second plurality of optical outputs.

摘要： A coolerless photonic integrated circuit (PIC), such as a semiconductor electro-absorption modulator/laser (EML) or a coolerless optical transmitter photonic integrated circuit (TxPIC), may be operated over a wide temperature range at temperatures higher then room temperature without the need for ambient cooling or hermetic packaging. Since there is large scale integration of N optical transmission signal WDM channels on a TxPIC chip, a new DWDM system approach with novel sensing schemes and adaptive algorithms provides intelligent control of the PIC to optimize its performance and to allow optical transmitter and receiver modules in DWDM systems to operate uncooled. Moreover, the wavelength grid of the on-chip channel laser sources may thermally float within a WDM wavelength band where the individual emission wavelengths of the laser sources are not fixed to wavelength peaks along a standardized wavelength grid but rather may move about with changes in ambient temperature. However, control is maintained such that the channel spectral spacing between channels across multiple signal channels, whether such spacing is periodic or aperiodic, between adjacent laser sources in the thermally floating wavelength grid are maintained in a fixed relationship. Means are then provided at an optical receiver to discover and lock onto floating wavelength grid of transmitted WDM signals and thereafter demultiplex the transmitted WDM signals for OE conversion.

摘要： Complex, coupled photonic microdevices are formed to include sub-wavelength-sized radial perturbations sufficient to create resonant cavities, where these devices may be formed along the length of a single optical fiber and coupled together to form relatively complex photonic devices. By carefully selecting the placement and separation of these local radius variations, and using microfibers (or other suitable arrangements) to couple optical signals into and out of the device fiber, resonances in the form of whispering gallery modes (WGMs) are created in the device fiber such that a number of coupled microstructures (such as ring resonators) may be formed.

The output waveguide is configured to receive a carrier signal including an unmodulated output wavelength channel. An input microcavity resonator is configured to derive a modulated electrical control signal from the modulated input wavelength channel. A first output microcavity resonator is configured to modulate the output wavelength channel in response to the control signal.
