| 英文摘要 | PURPOSE:To make the distribution of guided light in an electromagnetic field perfectly symmetric with respect to an axis and to attain high efficiency of coupling to an optical fiber by adhering optical waveguides formed in first and second substrates to each other to form an optical waveguide. CONSTITUTION:Proton exchange waveguides are formed on LiNbO3 substrates 1, 2 and annealed at 350 deg.C in the air for 1 hr to form optical waveguides 3, 4 of 5 mum width and 2 mum depth. The waveguides 3, 4 are washed, aligned with a mask aligner and adhered to each other and both ends are polished to form an incidence part 5. When semiconductor laser light having 0.8 mum wavelength is allowed to enter the resulting waveguide, emergent guided light is made nearly circular and the distribution of the guided light in an electromag netic field is made nearly symmetric with respect to the axis of propagation. When an optical fiber is coupled to the waveguide, loss measured at the coupled part is 0.8 dB. |
