Zusammenfassung:	Methods and apparatus for an optical system that can include a receiver to protect an optical sensor for damage. In one embodiment, a optical receiver includes a lens to receive an optical signal and a non-linear optical (NLO) element to receive an output from the lens, where the NLO element has an intensity dependent optical index. The receiver can include an optical sensor and an aperture located between the optical sensor and the NLO element.
