英文摘要 | PURPOSE:To facilitate the manufacture of a laser ray source, improve it in reliability, and enable it to be integrated into an IC by a method wherein a part of laser rays, which is advancing in an optical guidewave, is made to vary in phase through an electro-optical effect of an optical waveguide single crystal material to make the travel of an optical beam deflected. CONSTITUTION:A P electrode 18 (the sane as 4) of an optical beam deflection section is provided onto a center line of a region 21 of an optical waveguide. A region 23 is irradiated with an ion beam of an n-type dopant Se to form an n-type conductive layer on a part of a p layer so as to construct a P-N junction in a direction parallel to an active layer 15. In this process, a p-n-type junction is formed at the junction of the n-type conductive layer with a p active layer 15 by increasing the doping amount of Se. As a result, when a reverse bias voltage is applied on the P electrode 18, a depletion layer is formed in parts 22-1 and 22-2 is the region 21 of the active layer 15 to generate intense electric fields. Two intense electric fields are parallel to the active layer 15 and opposite to each other by 180 deg. in a direction. Therefore, a light wave is made to advance in phase at the part 22-1 and lag in phase at the part 22-2, and the light wave as a whole passing through the region 21 is deflected rightwards as shown by an arrow 8. The deflection angle is approximately proportional to an applied voltage. |
