Title: Production of thin film optical waveguide lens
Inventor: OKUNO MASAYUKI
IPC: C23F4/00
Filed: 1988-08-08
Abstract: PURPOSE:To produce the title compact thin film optical waveguide lens with a high degree of freedom in design by forming an electron-beam resist to be used as a mask into a rotation-symmetrical shape having a stepped film thickness distribution, and transferring the shape to a lower-layer material. CONSTITUTION:A lens material 4 having a thickness necessary to obtain a desired focal distance is laminated on an optical substrate consisting of a substrate layer 1, a lower clad layer 2, and a waveguide 3, and an electron-beam resist film 5 is applied thereon. The resist film 5 is patterned by the electron- beam drawing method into a rotation-symmetrical lens shape having a stepped film thickness distribution wherein the thickness decreases from the center toward the periphery. The shape is transferred to the lens material 4 by dry etching. An upper clad layer 6 is further laminated on the waveguide 3 to form a thin film optical waveguide lens. By this method, the degree of freedom in design is increased and the lens is miniaturized, which have not been attained by the conventional method.
