  • Compact add-drop multiplexer with low wavelength temperature sensitivity
    Patent number: 6647177
    Abstract: A compact add-drop multiplexer with low wavelength temperature sensitivity. In the present invention, a plurality of spacer rings is disposed between the optical elements of the add-drop multiplexer, and a heat curing epoxy or an ultraviolet curing epoxy adheres the optical elements to each other. The spacer rings are formed with a thermal expansion coefficient within a predetermined range to compensate for thermal stress of the WDM filter.
