Abstract
A device and method are disclosed for detecting light. The device includes a photodetector having at least one superlattice layer operative to generate an electrical signal in response to light incident thereon and one or more lenslets for directing light onto the photodetector.
Claims31
A device for generating an electrical signal in response to light, comprising:
- a photodetector including at least one superlattice layer operative to generate an electrical signal in response to light incident thereon;
- and
- one or more lenslets for directing light onto the photodetector.
A method of forming an image of an object, the method comprising:
- exposing a lenslet to light emitted from an object to cause the lenslet to direct the light onto a superlattice layer of a photodetector thereby causing the photodetector to generate an electrical signal in response to the light;
- and
- generating an image of the object from the electrical signal.
