摘要： The present invention is provided to obtain an inexpensive bidirectional optical module wherein a diffraction efficiency can be maximized at different diffraction order for light beam with different wavelength, and light usage efficiency is enhanced. The bidirectional optical module includes a light-emitting element for transmitting an optical signal toward an end of an optical fiber; a light-receiving element for receiving an optical signal from the end of the optical fiber; and a grating in which stair shapes are repeated with a predefined pitch. In the bidirectional optical module, a phase function is defined as phase-difference contour lines which is formed by making two light fluxes from predetermined positions interfere with each other on a surface arranged at a position of the grating. A planar pitch of the grating is formed such that values of the phase function form phase contour lines each representing an integer multiple of 360 degrees.

摘要： An echelon type diffraction structure 5a is formed on the flat optical surface of a lens 5, thereby ensuring easy designing and easy production of a diffraction structure as a microstructure. Further, the light of wavelength λ1 is applied to the diffraction structure 5a in a tilted position with respect to the optical axis of the lens 5 so that the first order diffracted light produced by the diffraction structure 5a travels along or parallel to the optical axis of the lens 5, with the result that improved light transmittance can be maintained. Further, a lens 7b is arranged between a light emitting device 7a and lens 5. Thus, the flat optical surface of the lens 5 is arranged on the side of the end face 1a of an optical fiber 1, thereby reducing the deterioration in aberration more effectively.

摘要： A plasma etching method for processing a substrate material, wherein a deposition process (S09) that uses a deposition gas as a process and an etching process (S11) that uses an etching gas as a process gas are alternately and repeatedly executed, thereby etching a substrate material, and a vacuuming process (S10, S13) is interposed between the two processes so that the process gas which has just finished being used is expelled out when the process gases are switched. Thus, the etching gas and the deposition gas do not mix during each process, thereby accurately creating a high-aspect-ratio recessed and protruding pattern on the surface of a substrate material.
