专利汇可以提供Thermooptic effect waveguide type optical switch专利检索,专利查询,专利分析的服务。并且PURPOSE:To pass and intercept light with short optical path length and to facilitate the adjustment of the optical axis of the input light by bringing a lens sphere into contact with the flank of a substrate under an electrode for heating the substrate and guiding in light to be modulated. CONSTITUTION:When a current accompanying a modulating voltage of 60V from a power source 6 to the electrode 3 for substrate heating is cut off by a switch 7, the spherical lens 1 arranged at the light input part diverges the light in the substrate 2 and when the current flows, on the other hand, the input light having passed through the spherical lens 1 reaches the light output part as it is through the light waveguide layer under the electrode 3. Consequently, the light is modulated. In this case, an input lead electrode 4 for voltage application and an output lead electrode 5 for voltage application are formed by sputtering at the same time with the electrode 3; the linear width of the contact between the electrodes 3 and 4 or 5 is 2-200mum and the angle theta of the spread at the part where the linear width between the electrodes 3 and 4 varies continuously is 35-36 deg..,下面是Thermooptic effect waveguide type optical switch专利的具体信息内容。
