High-speed DFB laser and EMLs

High speed reliable 1.55 mum AlGaInAs multi-quantum well ridge waveguide (RW) DFB laser is developed with a 9GHz -3dB bandwidth. A high speed self aligned constricted mesa 1.55 mum DFB laser is achieved with a 9.1GHz -3dB bandwidth and a more than 20mW output power. A cost effective single RW electroabsorption modulated DFB laser (EMLs) is proposed and successfully fabricated by adopting selective area growth techniques:. a penalty free transmission at 2.5Gbps over 280Km normal G.652 single mode fiber is realized by using this EML as light source. For achieving a better performance EMLs. a gain-coupled DFB laser with etched quantum wells is successfully integrated with a electroabsorption modulator (EAM) for a high single mode yield. the wavelength of a EML is tuned in a 3.2nm range by a integrated thin-film heater for the wavelength routing. a buried heterostructure DFB laser is also successfully integrated with a RW EAM for a lower threshold current. lower EAM parasitic capacitance and higher output power.
