Abstract :
Electrically-pumped continuous tunable vertical cavity surface emitting lasers (VCSEL) emitting in the 1530-1620 nm wavelength regime is reported for the first time. The VCSELs exhibit a continuous, repeatable and hysterisis-free wavelength-tuning characteristic. The VCSELs are directly modulated at 2.5 Gbps and has > 45 dB side mode suppression ratio (SMSR) over the entire tuning range. Wavelength locking is achieved in ∼200 usec by a simple universal locker.
