Characteristics And Applications Of The Short External Cavity Laser Diode , Jin-Yong Kim

Retrospective Theses and Dissertations

The characteristics of the external cavity laser diode are investigated. Emphasis is placed on the short external cavity configuration. The general governing model equations which include the multiple reflection effect are derived. It is shown that the coupling coefficient becomes a complex function of the external cavity length and the near field beam size of the laser diode due to the diffraction loss of an open resonator. The validity of this open resonator model is proven experimentally by the asymmetry in optical power versus external cavity length characteristic curve. For analysis of the ultra short external cavity laser, it is ...
