High density VCSEL arrays

Summary form only given. Top and bottom emitting 1D and 2D VCSEL arrays offer new perspectives in optical and electrical packaging and are therefore of high interest for future short haul parallel optical links, board-to-board and on-board high-speed optical interconnects. Results of short-wavelength multi-transverse mode VCSEL arrays demonstrating excellent uniformity, low threshold current, high modulation efficiency and multi-gigabit performance are presented.
