Optical interconnects integration on FR4 board with MSM photodetector and commercial optoelectronic devices

In this paper, a process is outlined for the integration of commercial bare die VCSEL and PiN PDs embedded in polymer waveguide on inexpensive printed wiring board (PWB) boards. The evanescent coupling efficiency of both PiN and metal-semiconductor-metal (MSM) PD from Siloxane waveguide is measured. This is the first demonstration of a process for embedding commercial PiN PDs in polymer waveguide for high speed chip to chip optical interconnects. Optoelectronic devices embedded in Siloxane waveguide on FR4 board such as embedded MSM PD in waveguide, PiN PD embedded in waveguide, embedded VCSEL and PiN on board and embedded VCSEL in waveguide with end mirror.
