【摘要】 报道了基于混合应变量子阱材料的半导体光放大器 (SOA)。利用张应变量子阱加强了TM模的增益 ,使之接近TE模的增益 ,从而使SOA的偏振灵敏度大为降低。在 150mA的偏置下 ,获得了 2 4dB的小信号增益和 1dB的偏振灵敏度。更多还原

【Abstract】 This paper reports 1.31 μm waveband semiconductor optical amplifier (SOA) based on tensile strained quantum wells and compress strained quantum wells. For TM mode the gain is enhanced by tensile strained quantum wells, the SOA performs with low polarization sensitivity. Under the condition of 150 mA bias current, the SOA shows 24 dB small signal gain and 1 dB polarization sensitivity.更多还原
