摘要： A high efficiency prism coupling device that comprises a substrate, an optical waveguide layer disposed on the substrate, a gap adjuster layer disposed on the waveguide layer and a prism secured to the gap adjuster layer through a dielectric adhesive agent. The gap adjuster layer has a refractive index which is lower than that of the waveguide layer. The gap adjuster layer has a recess formed therein for guiding an incident beam to the waveguide layer through a bottom portion thereof. The adhesive agent is disposed in and around the recess and has a refractive index which is higher than that of the waveguide layer. The prism is made from a dielectric material and disposed above the recess of the gap adjuster layer through the adhesive agent. The prism has a refractive index which is higher than that of the waveguide layer. The incident beam is introduced from outside through the prism, the adhesive agent and the bottom portion of the recess to the waveguide layer.

摘要： A light source emitting a light flux; a coupling optical system couples the light flux from the light source to a subsequent optical system by transforming it into a parallel light flux, an approximately convergent light flux or an approximately divergent light flux; a light deflector reflects the light flux from the coupling optical system with a deflection reflective surface, and deflects it; a scanning and imaging optical system condenses the deflected light flux from the light deflector onto a surface to be scanned as a beam spot; and a correcting optical system is provided for self correcting shift of focal position of the beam spot on the surface to be scanned occurring due to environmental change or the like. The correcting optical system comprises at least one pair of a resin-made lens having an anamorphic surface having a negative power in each of main scanning direction and sub-scanning direction and a glass-made lens having an anamorphic surface having a positive power at least in sub-scanning direction, and is disposed between the coupling optical system and deflection reflective surface.
