Time-Domain Large Signal Investigation on Dynamic Responses of the GDCC Quarterly Wavelength Shifted Distributed Feedback Semiconductor Laser
نویسندگان
چکیده
A numerical investigation on the dynamic large-signal analysis using a time-domain traveling wave model of quarter wave-shifted distributed feedback semiconductor lasers diode with a Gaussian distribution of the coupling coefficient (GDCC) is presented. It is found that the single-mode behavior and the more hole-burning effect corrections of quarter wave-shifted distributed feedback laser with large coupling coefficient can be improved significantly by this new proposed light source.

A Novel Design of Quarter Wave-shifted Distributed Feedback Semiconductor Laser for High-power Single-mode Operation
The spatial hole burning effect has been known to limit the performance of distributed feedback semiconductor diode lasers. As the biasing current of a single quarterly-wavelength-shifted distributed feedback diode laser increase, the gain margin reduces. Therefore, the maximum single-mode output power of the quarterly-wavelength-shifted distributed feedback diode laser is restricted to a relat...
متن کاملTheoretical comparison analysis of long and short external cavity semiconductor laser
In this paper, considering optical feedback as an optical injection, and taking in to account round-trip time role in the external cavity, a standard small signal analysis is applied on laser rate equations. By considering the relaxation oscillation (f2) and external cavity frequencies (f) ratio for semiconductor laser, field amplitude response gain, optical phase and carrier number for long ex...

We report, to the best of our knowledge, the first realization of a multi-wavelength distributed feedback (DFB) semiconductor laser array with an equivalent chirped grating profile based on equivalent chirp technology. All the lasers in the laser array have an identical grating period with an equivalent chirped grating structure, which are realized by nonuniform sampling of the gratings. Differ...
