摘要： A mechanical amplifier is disclosed for thermally tuning an optical filter. Two arms retain an optical fibre, and an expander is placed between the two arms. Ends of the arms are connected to each other, so that when there is a temperature variation, the distance between the two arms changes, thereby stretching or compressing the optical filter.

摘要： 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.

摘要： The present invention relates to a set-up and a method for repeatedly sending longitudinal displacement pulses through a length of optical fibre, the set-up using an actuator arrangement for exciting longitudinal displacement pulses, or waves, in an optical fibre. The arrangement comprises a bracket, a washer element, a piezo member arranged between the bracket and the washer element, and an optical fibre that is engaged with and extending through a passage in the washer element. The piezo member is operative, responsive to an applied voltage, to displace the washer element and the fibre engaged therewith, in the longitudinal direction of the fibre, with respect to the bracket. Thereby, a longitudinal displacement pulse may be excited in the optical fibre. The actuator arrangement may also, in the set-up according to the invention, operate as a sensor for sensing longitudinal displacements in optical fibres.

摘要： An acousto-optic filter includes an optical fiber with a longitudinal axis, a core and a cladding in a surrounding relationship to the core. The optical fiber has multiple cladding modes. At least one acoustic wave generator is included and made of a sufficiently high frequency piezoelectric material to produce a longitudinal acoustic wave. An acoustic wave propagation member has proximal and distal ends. The distal end is coupled to the optical fiber and the proximal end is coupled to the acoustic wave generator. The acoustic wave propagation member propagates the longitudinal acoustic wave from the proximal to the distal ends and excites the longitudinal acoustic wave in the optical fiber.

摘要： An acousto-optic filter includes an optical fiber with a first region and a second region. A first acoustic wave generator is coupled to optical fiber. The first acoustic wave generator produces a first acoustic wave that travels in a first direction in the first region. A backward-propagating wave is generated in response to propagation of the first acoustic wave along the optical fiber. The backward-propagating wave travels in an opposite direction relative to the first acoustic wave. A first acoustic wave propagation member is coupled to the optical fiber. A second acoustic wave generator is coupled to the optical fiber at the second region. The second acoustic wave generator produces a second acoustic wave that combines with the backward propagating acoustic wave.

摘要： The invention relates to fiberoptics. The invention is directed at widening the functional capacities of a filter by augmenting a length of an acousto-optical interaction on uniform acousto-optical structure and uniformity region of elastic vibrations. The inventive device comprises a cut of optical fiber and a radiator and an elastic vibration absorber rigidly connected thereto. The invention is characterized by the introduction into the device of a thin cylindrical shell used for spinning (completely or partially) optical fibers. In addition, the shell is fitted with at least one open slit parallel to the axis thereof. On the opposite sides of the slit, the radiator and the absorber are mounted along the length of the hole slit in a way making it possible to embrace the optical fibers. The inventive device provides a reflection factor R in the order of 0.3 within a filtration bandwidth ranging from 1 to 10 kHz.
