Injection-locked 1.55-/spl mu/m tunable VCSEL for uncooled WDM transmitter applications

We study the temperature effects on injection-locked vertical-cavity surface-emitting lasers (VCSELs) for use in wavelength-division-multiplexed (WDM) transmitters. We show that injection locking can be used to lock an uncooled VCSEL to the WDM grid while improving its analog performance.
