Abstract
Consecutive wavelength switching characteristics of a simple, compact, and
digitally wavelength-switchable laser based on V-coupled cavities are reported.
Wavelength switching through thermal and carrier injection effects is examined.
Without using band gap engineering for the tuning section, 26- and 9-channel
wavelength switching schemes are achieved via thermal and carrier injection effects,
respectively. The performances of these two tuning schemes are then compared.
