摘要： PROBLEM TO BE SOLVED: To provide an optical element, a light source unit, a optical scanner, and an image forming apparatus, in which a plurality of functions are integrated, and the reduction of the number of components, downsizing, and cost reduction are attained.
SOLUTION: The light source unit 1 is provided with a surface emitting laser 10 as a light source and a coupling lens 12. The light beam emitted from the surface emitting laser 10 shows a random polarization (TE polarization and TM polarization are included at random) and the light beam passing through a coupling lens 12 is linearly polarized light(TM polarization) having a predetermined direction. The coupling lens 12 has also a function as a polarizer and passes only the light linearly polarized in a certain direction. This is realized by generating structural double refraction by providing a fine ruggedness structure 2 having a periodic character on the surface 12a of the curved optical surface on the side of the surface emitting laser 10 of the coupling lens 12.

摘要： PROBLEM TO BE SOLVED: To provide an optical element of a phase modulation type having high light availability by attaining phase modulation of transmission light by means of a low aspect ratio structure like a sub-wavelength structure having a single height. SOLUTION: The optical element changes the phase of transmission light by spatially modulating the height of at least a part of structures 2, has a finer structure than the wavelength of usage light and, therefore, attains the phase modulation of transmission light by using a fine structure having a narrower period than incident wavelength with different heights. Further, when wavelength of usage light is λ, incident angle is θ, refractive index of an incident medium is n1 and refractive index of a structure 2 is n2, the period of the structure is λ/(n1sinθ+n2) or less, thereby, the occurrence of transmission light due to higher order diffraction is eliminated and the optical element having high light availability is attained.
