Coupling coefficient calculaltion of laterally coupled distributed feedback laser structure with metal surface gratings

We calculated the coupling coefficient of laterally coupled distributed feedback (LC-DFB) laser structure with metal surface gratings using both coupled mode theory and beam propagation method. The coupling coefficient of a 3 mum wide LC-DFB laser with 3rd order gratings fabricated by holographic li...

Zusammenfassung:We calculated the coupling coefficient of laterally coupled distributed feedback (LC-DFB) laser structure with metal surface gratings using both coupled mode theory and beam propagation method. The coupling coefficient of a 3 mum wide LC-DFB laser with 3rd order gratings fabricated by holographic lithography was estimated as approximately 7.9 cm -1 . Coupling coefficient dependence on structural parameters was also investigated.
