Abstract
We report the efficient tuning of lasing wavelength through distributed
Bragg reflector (DBR) laser, using PZT macrofiber composite (MFC) actuator.
The laser output power is not disturbed with imparted perturbation on output
grating in DBR laser. The lasing wavelength tuning was uniform, linear, and
has shown positive slope with driving voltage applied on MFC actuator. The
sizes of MFC actuators show significant effect on the tuning of lasing
wavelength. The certain criticalities of obtained results of lasing tuning,
output power stability, and narrow line peak width have been
reported.
