英文摘要	The present disclosure relates to a packaging approach for ensuring that high power optical modules incorporating VCSELs and VCSEL arrays remain eye safe. A VCSEL device or VCSEL package of the present disclosure may generally be configured certifying an optical device as eye safe such that the device is able to survive a single failure mode. In other embodiments, a multiple lens array is arranged above the VCSEL, which scatters the light into a wide range of angles such that a higher percentage of light will reach the photodetector located beside the VCSEL. In other embodiments according to the present disclosure, one or more methods and circuits are provided to detect and correct errors or failures caused by one or more unsafe conditions.
