Abstract :
The optical crosstalk between lasers in densely-packed multiple wavelength vertical-cavity photonic integrated emitter arrays is studied for multimode wavelength-division multiplexing applications. It is found that a significant number of photocarriers are generated by spontaneous emission of an adjacent laser. However, an appropriate prebiasing scheme or device design can reduce the crosstalk to <-20 dB
