Packaging Considerations For Semiconductor Laser Diodes
• A semiconductor laser diode is a device capable of producing a lasing action by applying a potential difference across a modified pn-junction. This modified pn-junction is heavily doped and contained within a cavity thus providing the gain medium for the laser. A feedback circuit is also implemented in order to control the amount of current sent to the laser diode. What do they look like...
