Abstract
A bar code reader comprises a semiconductor laser diode. A first end face of the laser diode is optically coupled to an end of an optical fiber. A second end face of the laser diode is optically coupled to a detector. The bar code is scanned at the free end of the optical fiber. This information is read by the semiconductor laser diode by way of optical feedback.
