Description
Technical Field
The utility model relates to the technical field of quantum communication, in particular to a disk box for coiling an optical fiber interferometer and an optical fiber interferometer module.
Background
In the related art, the rate of coding of a quantum communication system depends on the stability of the difference between the long arm and the short arm of the fiber interferometer. However, the long arm and the short arm of the fiber optic interferometer are easily affected by disturbance of external ambient factors (such as temperature and vibration of the ambient environment), and the disturbance affects the long arm and the short arm of the fiber optic interferometer to change, and the change often destroys the consistency of the difference between the long arm and the short arm of the fiber optic interferometer, thereby reducing the code yield of the quantum communication system.
Accordingly, there is a need to provide a stable, reliable mounting and pre-fixing structure for fiber optic interferometers used in quantum communication systems. Because the optical fiber interferometer can be effectively insulated and vibration-reduced and packaged only on the basis of stable and reliable installation and pre-fixing structures. Therefore, the disturbance influence of external ambient factors on the optical fiber interferometer can be reduced as much as possible, and the stability of the interference effect of the optical fiber interferometer is ensured.

Detailed Description
Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.
Referring to fig. 1, 2, 3, 4, and 5, a disk cartridge 100 for a coiled fiber interferometer of the present invention may include at least a coiling slot 101, a coupler slot 102, a barrier rib 103, and an opening 104.
In the disc cartridge 100 for coiling the optical fiber interferometer shown in fig. 1, 2, 3, 4, and 5, a coiling groove 101 may be formed along a side of the disc cartridge 100 and surround the disc cartridge 100, which may be used to coil and fix a portion of the input and output optical fibers 106 of the optical fiber interferometer 105; a coupler card slot 102, which may be formed at both sides of the disc cartridge 100 opposite to each other and communicates with the winding groove 101, may be used to define and receive a coupler 107 (i.e., a combiner or splitter of a fiber optic interferometer) of a fiber optic interferometer 105; a barrier rib 103 may be formed at the bottom of the inner cavity 108 of the disc cartridge 100, which may be used to wind and fix another portion of the input and output optical fibers 106 of the optical fiber interferometer 105; an opening 104 may be formed at a side of the disc cartridge 100 and communicates an inner cavity 108 of the disc cartridge 100 with the winding groove 101, wherein the input and output optical fibers 106 of the fiber optic interferometer 105 may be drawn out of the disc cartridge 100 through the opening 104.
The disc cartridge 100 for winding the optical fiber interferometer shown in fig. 1, 2, 3, 4 and 5 enables the optical fiber interferometer 105 to be firmly attached to the inside of the disc cartridge 100 based on the winding groove 101, the coupler clamping groove 102 and the barrier rib 103 on the disc cartridge, prevents the optical fiber interferometer 105 from being dislocated and loosened, and also largely prevents the optical fiber interferometer 105 from contacting with surrounding structures, so that a stable and reliable pre-fixing structure can be provided for subsequent further thermal insulation and vibration damping packaging, the effectiveness of the thermal insulation and vibration damping packaging is ensured, and the disturbance influence of external surrounding environmental factors on the interference effect of the optical fiber interferometer is further reduced.
In addition, as an example and not by way of limitation, in the disk cartridge 100 for a coiled optical fiber interferometer shown in fig. 1, 2, 3, 4, and 5, blocking pieces 109 may be formed on two side walls opposite to each other inside the coupler card slot 102. This prevents the coupler (i.e., the combiner or splitter of the fiber optic interferometer) from coming loose from the cartridge.
In addition, by way of example and not limitation, in the disk cartridge 100 for a coiled fiber optic interferometer shown in fig. 1, 2, 3, 4, and 5, the barrier ribs 103 may be formed uniformly in a circular arc shape at the bottom of the inner cavity 108 of the disk cartridge 100. With this configuration, another portion of the input and output fibers of the fiber optic interferometer can be uniformly coiled within the interior cavity of the cartridge, avoiding contact of the fiber optic interferometer with surrounding structures.
In addition, by way of example and not limitation, in the disk cartridge 100 for a coiled optical fiber interferometer shown in fig. 1, 2, 3, 4, and 5, the coiling groove 101, the coupler card groove 102, the barrier rib 103, and the opening 104 may be integrally formed. The integral structure not only makes the whole structure of the disk box more compact, but also reduces the processing complexity of the disk box.
In addition, as an example and not by way of limitation, in the disk cartridge 100 for the coiled fiber interferometer shown in fig. 1, 2, 3, 4, and 5, the disk cartridge 100 may be made using, for example, but not limited to, one of copper and aluminum. The metal material has large specific heat capacity, and can ensure the stability of the optical fiber interferometer to a certain extent.
In addition, by way of example and not limitation, the disk cartridge 100 for coiling a fiber optic interferometer shown in fig. 1, 2, 3, 4, and 5 may be used for coiling, such as, but not limited to, one of the following fiber optic interferometers: fiber Fabry-Perot interferometers (FPT), Mach Zehnder Interferometers (MZI), Michelson Interferometers (MI), and Sagnac Interferometers (SI).
Referring to fig. 6, the disk cartridge 100 for coiling the fiber optic interferometer shown in fig. 1, 2, 3, 4, and 5 may be included in a fiber optic interferometer module 110 as shown in fig. 6 to insulate the fiber optic interferometer 105 from the external ambient environment. Then, the fiber interferometer module 110 shown in fig. 6 can be subjected to thermal insulation and vibration reduction packaging to reduce the disturbing influence of external ambient factors on the interference effect of the fiber interferometer.
In the fiber optic interferometer module 110 shown in fig. 6, the shape of the case of the fiber optic interferometer module 110 may be adapted to the shape of the disk cartridge 100 for coiling the fiber optic interferometer shown in fig. 1, 2, 3, 4 and 5, and the fiber optic interferometer module 110 may be made of a material such as, but not limited to, teflon, polyimide, etc.
