SYSTEMS AND METHODS FOR CHIP-INTEGRATED INFRARED SILICON DETECTOR

摘要

Systems and methods for chip-integrated infrared silicon detectors are disclosed. In one aspect of the disclosed subject matter, a detector for detecting at least one electromagnetic field is disclosed. An exemplary detector can include a photodetector, a photonic crystal cavity, a spacer layer, and an incoupling element. The spacer layer can be disposed between the photonic crystal cavity and the photodetector. The incoupling element can be adapted to couple at least one input electromagnetic field into the photonic crystal cavity. The photonic crystal cavity can be adapted to upconvert the at least one input electromagnetic field to form at least one output electromagnetic field, thereby permitting detection of the at least one output electromagnetic field by the photodetector through the spacer layer. In another aspect, a method for upconverting an input field is disclosed. In another aspect, a method for integrating a photonic crystal cavity onto a photodetector is disclosed.
