Abstract

PURPOSE:To make possible working arbitrary elliptical shape lenses in a large amount without requiring positioning at all by using directional etching. CONSTITUTION:The terminal part of an optical fiber 1 is sandwiched by two sheets of Si substrates 3, 4 from above and below and is subjected to sputter etching by using dischargeable gas within a parallel electrode type plasma etching device, thence it is turned upside down and is subjected to sputter etching, whereby it is worked to a flat elliptical shape. Thence, the terminal part is cut to a suitable length, after which electric discharge is caused by applying high-voltage high- frequency voltage between the discharge electrodes, whereby the glass having been worked to a flat elliptical shape is melted, thus it is made into an elliptical shape having smooth curved parts by its surface tension.
