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 …

Narrow frequency-band laser with optical feedback
… the construction of a narrow frequency-band laser with optical feedback. We use a distributed Bragg reflector (DBR) laser diode centered at the cesium D₂ transition wavelength, [gamma] = 852 nm. The linewidth of this diode is reduced by several orders of magnitude by means of optical feedback …

Optical pulse distortion and manipulation through polarization effects and chromatic dispersion
… availability of ultra-long length chirped fiber Bragg gratings (FBG). Their enormous chromatic dispersion enables methods of improving current techniques in sensing and high speed optical sampling. In one experiment, we modulate the frequency of a standard distributed Bragg reflector (DBR) laser, …
