• Subjects: Distributed Bragg reflector (DBR) laser; selective area growth (SAG); electro-absorption modulator (EAM)

A distributed Bragg reflector (DBR) laser and a high speed electroabsorption modulator (EAM) are integrated on the basis of the selective area growth technique. The typical threshold current is 4 to 6 mA, and the side mode suppression ratio is over 40 dB with single mode operation at 1550 nm. The DB...
