Abstract:
A light-emitting device comprising VCSELs formed in a die. The VCSEL distribution is characterized by an essentially linear decrease in VCSEL density over the die from a highest VCSEL density in a first die region to a lowest VCSEL density in another die region. The VCSELs share a common anode and a common cathode for collective switching of the plurality of VCSELs. A method of manufacturing such a VCSEL die is also described.
