Abstract :
The performance of 1.3 μm InGaAsP buried heterostructure lasers with both n- and p-type contacts fabricated on one side is discussed. The lasers are flipchip bonded to Si wafers. The DC characteristics of the laser (Ith≃12-15 mA, η=0.19 mA/mW) are identical to those obtained on conventional metal heatsinks. The modulation bandwidth exceeds 3 GHz at a bias current of 20 mA. A bandwidth of 1.5 GHz can be obtained at a current of only 3 mA above threshold. The flipchip bonded lasers are shown to be stable up to at least 65°C
