Abstract: A reconfigurable thin-film photonic filter weight bank comprises at least one photodetector and at least one optical filtering device comprising a pair of reflective thin film stacks with an interstitial medium cavity therebetween forming an optical cavity. Operation of a bank occurs when the reflective film is more selectively reflective to a range of frequencies and is more translucent to frequencies outside the range. The bank can reconfigurably weight signals by varying the cavity sizes or complex indices of refraction, with one photodetector integrating the weighted signals. Detectors can also be embedded inside the individual cavities to output unweighted, but demultiplexed, electrical signals. A neuromorphic opto-electronic system comprises a plurality of interconnected artificial optical neurons, each including at least one thin film neuromorphic opto-electronic device with a reconfigurable thin-film photonic filter weight bank. Related methods are also disclosed.

Abstract: A hybrid neuromorphic computing device is provided, in which artificial neurons include light-emitting devices that provide weighted sums of inputs as light output. The output is detected by a photodetector and converted to an electrical output. Each neuron may receive output from one or more other neurons as initial input. Interconnects between neurons may be optical, electrical, or a combination thereof. The neurons also may provide imaging sensor and/or display capabilities.
