چکیده

A model is reported that describes a bidirectional homogeneously broadened index-antiguided (IAG) slab laser having arbitrary single-pass gain and distributed losses. Maximum extraction efficiency and corresponding optimum output coupling are determined for various values of unsaturated gain and loss per pass. A method is proposed to determine the intrinsic laser parameters from output power measurements.

Active Mode Locking With Hybrid Lasers

We present the results of a numerical study of active mode locking with hybrid lasers which contain an inhomogeneously broadened laser medium and a homogeneously broadened laser medium. The spectral, pulse, and gain characteristics of actively mode-locked hybrid lasers and the influence of the unsaturated gain, the saturation power, and the homogeneous linewidth on the pulse coherence and bandw...

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...

Trends in semiconductor laser design:

The trade-off between the effect of leakage suppression and the increase of related optical loss due to placement of the p-doping in 1.3-1.55μm InGaAsP MQW edgeemitting lasers is detailed. The effect of the Zn doping profile on laser characteristics is illustrated by experimental results obtained for telecom lasers and high power lasers. The design approach combining broadened waveguides with p...

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...
