摘要： This invention provides an optical head apparatus in which a grating coupler (8), which is formed on a circular region which has a center on an axis (18) and has a periodical structure with dents and projections in a configuration of concentric circles or spirals around the axis (18), input-couples laser light (7) emitted from a semiconductor laser (5) and turns it into waveguided light (16B) which transmits in a waveguiding layer (15B). The waveguided light (16B) is converted, in a region where the waveguiding layer (15B) and a waveguiding layer (15A) overlap each other, to waveguided light (16A) which transmits in the waveguiding layer (15A). By a grating coupler (9), formed on a ring-shaped area which is located around the axis (18), which has a periodic structure with dents and projections of a configuration of concentric circles or spirals around the axis (18), the waveguided light (16A) is radiated and focused onto points (FA), (FB) and (FC) which are located on the axis (18). Light reflected from a reflecting surface (19) is input-coupled by the grating coupler (9) and is converted to waveguided light (21) which transmits through the waveguiding layer (15A) toward the center. The waveguided light (21) is radiated at the innermost edge of the waveguiding layer (15A) and the amount of radiated light is detected by a light detector (10) to obtained control signal and playback signals.

摘要： The voltage signal applied between a conductive thin film (2) and a transparent conductive thin film (6) changes the aligning direction of a liquid crystal layer (5) near the surface of a waveguide layer (4) so that the refractive index of the liquid crystal (5) for waveguide light (8) is changed thereby to change the equivalent refractive index for the waveguide light (8), and thus the diffraction angle of the radiated light (9) from the waveguide layer (4) including the cyclic structure (3G) formed therein is also changed to deflect the radiated light. If the waveguide light (8) is propagated in the direction perpendicular to the longitudinal direction of the arrangement of the cyclic structure (3G), which is arranged in the form of a concentric circle, and the radiated light (9) from the waveguide layer (4) is focused at a focusing point outside the waveguide layer (4), the deflection of the radiated light (9), which is caused by applying a voltage signal between the conductive thin film (2) and the transparent conductive thin film (6), produces a displacement of the focusing point. In particular, if the conductive thin film (2) or the transparent conductive thin film (6) is divided into a large number of sections and voltage signals are individually applied to such sections, the focusing point (F) can be displaced to any optional point.

摘要： A method and system for creating and co-aligning a first array of optical beams with a second array of optical beams. In a preferred application the invention is used in a cross connect optical switch. A first set of alignment beams are created and added to and aligned co-axially with each of the first set of parallel collimated cross-connect communication beams. A second set of alignment beams are created and added to and aligned co-axially with each of the second set of parallel collimated cross-connect communication beams. A preferred embodiment includes an injection unit with a “point” infrared light source such as a vertical cavity surface emitting laser (VCSEL) operating in the near infrared at 850 nm and having a divergence of about 30 degrees. The beam from this source is collimated with collimator optics to produce a collimated beam with a cross sectional dimension of about 16 millimeter×16 millimeters. This collimated beam is separated into 128 separate beams with a mask having 128 0.6 mm diameter apertures that are positioned to align the 128 separate parallel beams with the communication beams from a fiber bundle.

A backlight 18 which is provided on a backside of an active matrix panel 13 comprises monochromatic light sources 18a-18c for emitting each monochromatic light of red, blue or green, and a picture of each color is displayed in a time division. While reading a picture, the picture of the components of red, blue and green are read at each simplex pixel by using each of the monochromatic light sources 18a-18c sequentially. A picture at a pixel P1 are read by storing a predetermined electric charge only at the photodiode 25 of the pixel P1 and exposing the photodiode 25 as well as making a liquid crystal layer 14 corresponding to every two pixels P1vertically and horizontally a transmission state, and an original picture is read at all pixels by repeating similar operation at each of pixels which are adjacent to the pixel P1.
