Abstract
We present measurement results of compact and efficient InAlAs-InGaAs metal-semiconductor-metal photodetectors integrated on silicon-on-insulator (SOI) waveguides. These thin-film devices are heterogeneously integrated on the SOI substrate by means of low-temperature die-to-wafer bonding using divinyldisiloxane benzocyclobutene (DVS-BCB). The responsivity of a 30-mum-long detector is 1.0 A/W at a wavelength of 1550 nm and the dark current is 4.5 nA at a bias voltage of 5 V.Keywords
