Abstract
The invention provides a fiber pigtail assembly wherein a polarization maintaining fiber is soldered directly to a mounting pad without a sleeve or a ferrule therebetween. A portion of the polarization maintaining fiber near a fiber end is embedded in a vertical slow axis orientation within an asymmetrical solder ball having a flat portion for adhering to the mounting pad. The vertical slow axis orientation of the polarization maintaining fiber within the solder ball enhances power stability and polarization extinction ratio properties of optical modules utilizing the invention.
