Abstract
The mode coupling properties of highly-birefringent tuneable LPGs formed in HC-PBGF are presented. The mode coupling from the fundamental core mode to higher-order guided mode of a HC-PBGF is obtained by use of periodic mechanical pressure. By adjusting the linear polarization state of a light source, we observed the separately-coupled higher guided mode in accordance with the axis of the pressure on the HC-PBGF due to high birefringence caused by the asymmetric structure of the HC-PBGF under pressure.
