Abstract :
AlGaInAs selective area growth on a masked InP substrate has been investigated to develop a spot-size converter integrated laser diode. After migration blocking area was applied to suppress surface migration effect, selective grown AlGaInAs layer shows improved characteristics in PL measurement. The threshold current was 25 mA and 62 mA at 25 °C and 85 °C, respectively. The FWHMs (full width at half maximum) of horizontal and vertical far field pattern were reduced from 25°; and 42° into 22° and 30°, respectively.
