Fast frequency tuning characteristics of a FM laser based on the integrated MQW DFB laser/EA modulator device

Using the selective-area-growth (SAG) technique we have recently successfully fabricated FM lasers based on the integrated DFB/EA modulator devices. The InGaAs/InGaAsP MQW device with a separate confined heterostructure (SCH) and a planar semiinsulating buried-heterostructure (BH), was grown in one primary growth by low-pressure MOCVD. The lasing wavelength is around 1.551 /spl mu/m.
