ADJUSTABLE GRID TRACKING TRANSMITTERS AND RECEIVERS

摘要

Optical telecommunication receivers and transmitters are described comprising dispersive elements and adjustable beam steering elements that are combined to provide optical grid tracking to adjust with very low power consumption to variations in the optical grid due to various changes, such as temperature fluctuations, age or other environmental or design changes. Thus, high bandwidth transmitters or receivers can be provides with low power consumption and/or low cost designs.

主权项

1. An adjustable optical telecommunication transmitter comprising:
a plurality of light emitting elements that emit optical signals chromatically spaced from each other; a dispersive element comprising a dispersive structure, a first interface providing a plurality of optical channel paths being optically coupled to the plurality of light emitting elements and to the grating, and a conjugate spatially-extended second interface to receive chromatically combined signals from the dispersive structure; and an adjustable beam steering element optically connected to the first interface or to the conjugate spatially-extended second interface.
