Pulse transformer laser diode package

摘要

A package for matching the characteristic impedance of a transmission line to the impedance of a pulsed semiconductor laser diode so that short duration pulses of light can be produced with a fast repetition rate. The package mounts the laser diode on the center post of a one turn secondary of a toroidal transformer whose multiturn primary is connected to the transmission line. Not only does this allow the matching of the characteristic impedances, but the center post provides heat sinking for the diode.
