Abstract: PURPOSE: A focusing angle measuring apparatus of a focusing waveguide grating coupler is provided to precisely measure a focusing angle of the focusing waveguide grating coupler by using a wide-band optical system, thereby minimizing process and design errors. CONSTITUTION: Light radiated from a wide-band light source(201) is guided into one plane of an image detecting device(211) through a photo guide(202), openings(203,205,206), a relay lens(204), a focusing lens(208) and a beam splitter(207) so that an image of a focusing grating(210) is formed on the plate of the image detecting device(211). At the same time, light is diffracted by means of the focusing grating(210) so that a focus(213) of light is formed. Focusing light(215) is formed on one plane of an image detecting device(211) by means of the focusing lens(208). That is, a shape of the opening(205) is formed on the plane of the image detecting device(211).

Abstract: PURPOSE: A micro near-field optical data storage head using an SIL(Solid Immersion Lens) is provided to use the SIL for a big size lens, and to use diffraction elements for the rest parts, thereby minimizing the size. CONSTITUTION: An optical waveguide(201) has a plane shape. At least more than one condensing diffraction grating(203) is attached to one of both sides of the optical waveguide, and changes a path of an incident light(202) to an SIL(205). More than one optical division diffraction grating(210) is located between a light source and the condensing diffraction grating, and changes a path of a signal light(209). The SIL is composed of a curved part and a plane part, and concentrates the incident light on one point of the plane part. A coil(206) is attached to an option position of an optical storage head, and generates a magnetic field. The curved part of the SIL is formed on a sphere, hemisphere, or super-hemisphere, to make the incident light diffracted by the condensing diffraction grating form an optical point less than diffraction limits.

Abstract: PURPOSE: Tracking method and device for a near-field recording of high density are provided to detect a change in an optical signal generated in diffraction by a pit by using a photo diode. CONSTITUTION: A flying head of a suspension is approaching to a disk recording medium for recording and reproducing data. A beam is transferred from a light source to an optical probe by passing through a beam splitter, an optical waveguide, and the suspension. A reflected beam progresses toward a signal processor for detecting a signal. Herein, signals(204a,204b) diffracted by a pit(213) are detected by photo diodes(206a,206b) at the flying head. Incidence beam(201) is concentrated on an SIL(Solid Immersion Lens)(203) by an object lens(202). The beam is signal processed by an adder(208), a subtracter(209), and a divider(210) for generating a tracking signal. In case of the incidence beam in symmetrical state, the beams are symmetrically diffracted for the photo diodes to detect the beam of uniform strength.
