Optical coupling apparatus |
摘要 |
In an optical coupling apparatus, an optical isolator and an optical fiber are arranged inside a pipe of a side surface of a package. A distal end of the optical fiber is arranged within a range of 3.0 mm from an inner/outer surface of the side surface of the package and a distance from a laser diode to the distal end is within a range from 3.5 to 7.5 mm. Distance from the inner side surface of the package to a Peltier device is within a range of 6.0 mm. A metallize pattern film applied to a terminal substrate of the package and the Peltier device are connected through wiring bonding and a connection position is closer to the optical fiber than a lead terminal provided to the terminal substrate of the package that corresponds to the Peltier device.
