HIGH SPEED PHOTO DIODE MODULE

摘要

The method for manufacturing high speed photo diode module comprises the steps of: connecting an Au line to a portion by die bonding ofsoldering a photo diode(PD;14) on a ceramic sub-mount(13) and soldering the sub-mount(13) inside a PD base(26); attaching a hybrid substrate(12) in a metal case(11) for module and fixing an external terminal pin(23) using a teflon ring; inserting a GRIN rod lens(18), a spacer(19) and a fiber ferrule(20) into a fiber ferrule housing(17) in sequence after inserting the optical fiber(21) into the fiber ferrule(20); aligning for a light to be incident into the photo diode(14); forming a sub-module; and wire-bonding of the sub-mount(13) and a pre-amplifier.
