ABSTRACT:
An optical pickup using an optical fiber module which includes optical fibers is provided, which can be small-sized and utilize a light beam from a light source at high efficiency. The optical pickup includes: an optical fiber module20, in which an optical fiber10consists of: a first optical fiber11which is a field-distribution converting fiber and a second optical fiber12whose core has birefringence, both the optical fibers11and12are connected to each other at one end thereof, and the laser light beam L emitted from the semiconductor laser1is made to enter the other end of the first optical fiber11; an optical head having at least an objective lens; an optical detector; wherein the optical fiber10is used as optical wiring to lead the laser light beam L emitted from the semiconductor laser1into the optical head.
