Document Type and Number:
Japanese Patent JP3360074
Kind Code:
B2
Abstract:
Characteristics are rendered variable and high-functional by using the side-pressure inductive polarization mode coupling of a PMF to thereby change the position and magnitude of a side pressure. An input light is incident via a polarizer (2), and an outgoing light is output via the PMF (1) and another polarizer (3). Light may enter and go out in an opposite way. The PMF (1) has two polarization axes orthogonal to each other, and the polarization axis of the polarizer (2) is coupled so as to agree with one end of the polarization axis of the PMF (1). The polarization axis of the polarizer (3) is coupled so as to agree with one end of the polarization axis of the PMF (1). The PMF (1) induces polarization mode coupling when a polarization light tilted a specified angle with respect to the polarization axis is incident to apply a side pressure to the PMF (1). Characteristics/functions can be changed by changing the position and the magnitude of a side pressure by an application unit (5) so that the length of the PMF (1) of a basic structure can be easily set precisely.
