OPTICAL COUPLER COMPRISING A MOLDED OPTICAL INTERPOSER TOGETHER WITH A PIC AND 2 POLARIZATION SELECTIVE ELEMENTS ENABLING ISOLATION AND/OR POLARIZATION MANAGEMENT
Abstract
The invention describes an apparatus that implements efficient coupling between a photonic integrated circuit (PIC) and a second optical element such as a fiber or laser, while at the same time allowing for efficient polarization management and/or optical isolation. It enables the packaging of PICs with large single mode fiber counts and in- and out-coupling of light with arbitrary polarization. The apparatus comprises a glass interposer that contains at least one polarization selective element together with a pair of lenses transforming a beam profile between the 2nd optical element and a polarization selective coupler on the PIC. The invention also comprises a method for fabricating the apparatus based on a subassembly of building blocks that are manufactured using wafer-scale high-precision glass-molding and surface treatment(s) such as thin-film coating.
