Abstract
A transmitter optical module that provides an LD, a first lens with a focal point aligned with an optical output point of the LD, a second lens that generates an optical output of the first lens as a concentrated optical signal, and a third lens that provides an optical output of the second lens in an optical fiber. The second lens is set at a position offset toward the third lens from a position at which the second lens outputs a collimated optical signal. The third lens concentrates an optical output thereof within the optical fiber.
