英文摘要	An array of vertical-cavity surface emitting lasers (VCSELs) may be fabricated with very high fill-factors, thereby enabling very high output power densities during pulse, quasi-continuous wave (QCW), and continuous wave (CW) operation. This high fill-factor is achieved using asymmetrical pillars in a rectangular packing scheme as opposed prior art pillar shapes and packing schemes. The use of asymmetrical pillars maintains high efficiency operation of VCSELs by maintaining minimal current injection distance from the metal contacts to the laser active region and by maintaining efficient waste heat extraction from the VCSEL. This packing scheme for very high fill-factor VCSEL arrays is directly applicable for next generation high-power, substrate removed, VCSEL arrays.
