    • There is provided a bistable element in which not only can miniaturization be further carried out in comparison with a conventional bistable element, but also it is possible to obtain a further wide bistable hysteresis window. The bistable element 100 includes: a multi-mode interference optical waveguide 1 provided on a substrate 10, and having two ports formed in one end face thereof, and one port formed in the other end face; a first group of optical waveguides 2 provided on the substrate 10, and including two optical waveguides (a first optical waveguide 2a and a second optical waveguide 2b), each of which has one end face connected to a corresponding port formed in the one end face 1a of the multi-mode interference optical waveguide 1; and a second group of optical waveguides 3 provided on the substrate 10, and including one optical waveguide, which has one end face connected to a corresponding port formed in the other end face 1b of the multi-mode interference optical waveguide 1, wherein the multi-mode interference optical waveguide 1 includes a saturable absorbing region in which saturation in an amount of absorbed light is caused by the fact that an absorbing coefficient is reduced as an intensity of incident light becomes larger.
    • 提供了一种双稳态元件,其不仅可以与传统的双稳态元件相比进一步实现小型化,而且可以获得更宽的双稳态滞后窗。 双稳态元件100包括:设置在基板10上的多模干涉光波导1,在其一个端面形成有两个端口,在另一端面形成一个端口; 设置在基板10上的第一组光波导2,并且包括两个光波导(第一光波导2a和第二光波导2b),每个光波导具有连接到形成在一个端面中的对应端口的一个端面 1a的多模干涉光波导1; 以及第二组光波导3,其设置在基板10上,并且包括一个光波导,其具有连接到形成在多模干涉光波导1的另一端面1b中的对应端口的一个端面,其中多 模式干涉光波导1包括饱和吸收区域,其中吸收光量的饱和是由于随着入射光的强度变大而吸收系数降低的事实。

    • The present invention relates to a variable optical filter that can be used to filter an incoming signal, attenuate an incoming signal or in one configuration switch an incoming signal from one path to another. The present invention has found that an accurate and economical variable optical filter can be created by using an elastomeric material having a high coefficient of expansion in cooperation with a means for locally varying the temperature of the elastomeric material as an actuator for moving a reflective surface within the optical filter. The actuator can be operated in a controlled manner for example, to effect a tilt of the reflective surface for switching or attenuating an optical signal, or to vary the resonant wavelengths of a resonant cavity between partially reflective surfaces. In accordance with the invention there is provided, a variable optical filter comprising an input port and an output port; a first at least partially reflective surface disposed to receive a beam of light launched from the input port; an elastomeric material for supporting and varying the position of the at least partially reflective surface with respect to the input port; a heater for applying variable amounts of heat to the elastomeric material to move or pivot the at least partially reflective surface relative to the input port; and, control means for controlling the heater and for providing a signal to apply variable amounts of heat.
