While previous predictions were based on Volterra series in conjunction with a simple device model, the present approach is based on harmonic-balance simulation in conjunction with a nonlinear large-signal device model. The present approach is validated by the agreement between simulations and measurements under different bias, matching and input conditions as well as tone separations. The present result is consistent with the Volterra-series analysis of the effect of baseband termination impedance on the intermodulation asymmetry.","PeriodicalId":269944,"journal":{"name":"GaAs IC Symposium.

Top and bottom emitting arrays offer new perspectives in optical and electrical packaging and are therefore of high interest for short haul parallel optical links, board-to-board and on-board ultra high-speed optical interconnects. Bandwidth requirements are increasing rapidly. The limits of VCSEL arrays in terms of modulation speed are analyzed and RF device optimization is discussed. Device and package limitations have to be considered. Important system level implications are also pointed out. Results of 850 nm multitransverse mode VCSEL arrays demonstrating excellent uniformity, low threshold current, high modulation efficiency and excellent multi-gigabit performance are presented.
