چکیده

Abstract Fresnel diffraction dominated fields propagating at glancing angles in a wide planar and rectangular optical waveguides are considered. Both schemes are characterized numerically with multi-harmonic interaction. Resonant effect in terms of the energy gain versus geometry parameter is demonstrated. It is found that adjacent harmonics play a dominant role in the performance at short wavelengths. Performance parameters are calculated for proof-of-principle experiment with moderate laser beam intensities.

Using of Broadened Asymmetric Waveguide Structure for 980nm Diode Laser

Laser diode beam divergence is the main parameter for beam shaping and fiber optic coupling. Increasing the waveguide layer thickness is the conventional method to decrease the beam divergence. In this paper, the broadened asymmetric waveguide is introduced to decrease the divergence without increasing the optical power. The asymmetric waveguide was used to shift the vertical optical field to n...

Improving the Thermal Characteristics of Semiconductor Lasers Using a New Asymmetric Waveguide Structure

   Self-heating leads to a temperature rise of the laser diode and limits the output power and efficiency due to increased loss and decreased differential gain. To control device self-heating, it is required to design the laser structure with a low optical loss, while the heat flux must spread out of the device efficiently. In this study, a new asymmetric waveguide design is proposed and th...
