摘要:
An optical circuit module in which an optical fiber array and an optical circuit substrate are connected, the optical fiber array including a groove substrate in which a groove for optical fiber alignment is formed, a pressing plate stacked on and bonded to the groove substrate, and an optical fiber bonded to and fixed in the groove of the groove substrate, and the optical circuit substrate including an input/output waveguide. In a connection surface of the optical circuit module, an area of a common portion in a cross section of the optical circuit substrate and the pressing plate is larger than an area of a common portion in a cross section of the optical circuit substrate and the groove substrate.
