摘要：
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 uf photocarriers are generated by spontaneous emission of an adjacent laser. However, an appropriate prebiasing scheme or device design can reduce the crosstalk to < -20dB.
