Fabrication and measurements of surface-etched grating distributed Bragg reflector laser [PDF]

, 2012
A laser diode emits light at a specific wavelength band and can be used in specific applications depending on its wavelength. However, the bandwidth of the laser gain is relatively broad, so a distributed Bragg reflector (DBR) laser is used to make a ...

Efficient Lasing Wavelength Tuning in Distributed Bragg Reflector Fiber Laser Using PZT Macrofiber Composite Actuator

, 2010
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.
