Passively aligned fiber-optic transmitter integrated into LTCC module

We studied the possibilities of LTCC (low temperature cofired ceramics) technology to fabricate fiber-pigtailed transmitter arrays using surface-emitting sources, such as VCSELs, equipped with vertical-mounted multimode fiber pigtails. The designed LTCC module can be mounted vertically on a printed-circuit-board (PCB), thus providing small, essentially one-dimensional PCB footprint.
