| 摘要 |
Systems are disclosed that utilize electrical signals from detectors of an imaging focal plane array or antenna elements of an antenna array to modulate optical signals. Antenna or focal plane array elements are coupled to optical waveguides by way of whispering gallery mode resonators made of electro-optic material. The resonators modulate optical signals in the waveguides based on the electrical signals from the detectors/antenna elements. The signals received by the array are converted into the optical domain, allowing subsequent optical processing and/or distribution. Each detector/antenna element involved can be identified by the specific wavelength and waveguide through which its signal is coupled, enabling subsequent optical processing of the signals such as by wavelength division multiplexing systems. Additionally disclosed are imaging sensor photonic systems that include WDM components and other optical components such one or more optical narrow-band amplifiers and/or filters. Related electro-optic modulation and tuning methods are also described. |
