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

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 narrow linewidth laser. The thesis discusses semiconductor lasers that use surface-etched DBR along with the physics of both the semiconductor and the DBR laser. The topics addressed are the fabrication of the broad area laser, ridge waveguide laser, and distributed Bragg reflector broad area and ridge waveguide laser. The thesis reports on the characterization of the laser with different measurements and the physics behind each measurement.
