Laser transmitters are used in a number of applications including cd players, code readers and voice and data transmission over optical fiber. The lasers used in these applications are historically edge emitting lasers housed in a TO-Hermetic metal can for improved reliability and thermal dissipation, In many cases a photo diode is also included in the metal can to provide automatic power control of the laser. Motorola has developed a new laser technology which uses a low cost high performance vertical cavity surface emitting laser [VCSEL] technology. These will also be packaged in TO-56 metal cans for socket compatibility and will provide improved life, lower cost, and superior performance.
