We design and fabricate wide wavelength range directly modulated lasers (DMLs) on the same
InP wafer to realize a large-capacity monolithically integrated light source array up to 1 Tb/s.
We demonstrate a 25.8-Gb/s push–pull operation over a 30-nm wavelength range, which is
conventionally about 14 nm for 100 GbE applications. To extend the operating wavelength range, we
design the wavelength dependence of the differential gain
