Abstract
An aperturefor producing an evanescent wave is provided at an n-Au electrode. The apertureis directed roughly perpendicularly to a direction in which end facesof an active layerof an optical device oppose to each other, and therefore, laser light generated in the active layeris made incident in the form of the p-polarized light. By the incidence of the p-polarized laser light, an evanescent wave of a comparatively great intensity is obtained from the aperture. With this arrangement, an optical device capable of obtaining an evanescent wave of a comparatively great intensity is provided.
