An optical path switching device comprises a light transmitting portion, a first electrode layer, a second electrode layer, a first adhesive layer, a second adhesive layer, a first supporting portion and a second supporting portion. The light transmitting portion has a plurality of refracting regions wherein the refractive indexes of a light can be uniformly controlled by the electro-optic effect in the direction perpendicular to the traveling direction of the light, and the thickness of the light transmitting portion changes along the traveling direction of the light. The first electrode layer and the second electrode layer are so formed as to sandwich the light transmitting portion and as to cover at least a part of the refracting regions. The first supporting portion is tightly arranged on a side of the first electrode layer, which side is out of contact with the light transmitting layer, via the first adhesive layer. The second supporting portion is tightly arranged on a side of the second electrode layer, which side is out of contact with the light transmitting layer, via the second adhesive layer.

Beam shaping means may have a shaping ratio set to allow a light beam emitted from a semiconductor laser and having an elliptic intensity distribution to have an ellipticity of no more than two to obtain a spot achieving high light availability and reduced in size. Furthermore, the shaping ratio can be set to no more than 2.5 to allow a polalized-beam splitter (light separation means) and other components to be arranged in a converged flux passing between the semiconductor laser and a collimator lens.

A mode splitter and the magneto-optical pick-up device including the mode splitter. The mode splitter includes a tapered waveguide portion whose thickness gradually becomes thin so that a light of at least one mode can be cut off. An emission position of a light wave can be varied depending on its mode. In this mode splitter, the emission position of the light wave of each mode can be adjusted by changing a thickness of the tapered waveguide, thereby improving the degree of freedom in designing the device.
