    • A temperature controlled optical coupling device of the present invention includes an optical coupling substrate (2) carrying metal electrodes (1) on its rear. An electrode substrate (6) carries metal electrodes (3) on its front. A plurality of thermoelectric elements (4) are also carried on the front of the electrode substrate (6) and connected to leads (5). A light emitting element or similar optical element (8) and an optical fiber (7) are mounted on the substrate (2) with their optical axes aligned with each other. Also mounted on the substrate (2) is a thermistor (9) for temperature measurement. The thermoelectric elements (4) are directly connected to the metal electrodes (1) and are connected in series by the metal electrodes (1) and metal electrodes (3). When a voltage is applied between leads (5), a current flows through the thermoelectric elements (4). As a result, the substrate (2) is selectively heated or cooled due to the Peltier effect, controlling the temperature of the thermoelectric elements (4). The structure is small size and low cost and needs a minimum of power for temperature control.
    • 本发明的温度控制光耦合装置包括在其后部承载金属电极(1)的光耦合基板(2)。 电极基板(6)在其前方承载有金属电极(3)。 多个热电元件(4)也被承载在电极基板(6)的前部并连接到引线(5)。 发光元件或类似的光学元件(8)和光纤(7)以其光轴彼此对准的方式安装在基板(2)上。 也安装在基板(2)上的是用于温度测量的热敏电阻(9)。 热电元件(4)直接连接到金属电极(1),并通过金属电极(1)和金属电极(3)串联连接。 当在引线(5)之间施加电压时,电流流过热电元件(4)。 结果,由于珀尔帖效应,基板(2)被选择性地加热或冷却,从而控制热电元件(4)的温度。 结构体积小,成本低,需要最小的温度控制功率。
