Description

Technical Field

[0001] This utility model relates to the technical field of silicon photonic modulator components, specifically an anti-vibration silicon photonic modulator. Background Technology

[0002] Silicon optical modulators, especially silicon-based electro-optic modulators, are key components in optical interconnects, optical computing, and optical communication systems, responsible for converting electrical signals into optical signals. The working principle of silicon optical modulators is primarily based on the electro-optic effect, utilizing the electro-optic effect of crystals to change the refractive index or birefringence of the crystal by controlling an external electric field, thereby altering the phase or intensity of the output light wave. The silicon optical modulator housing is a crucial component, primarily used to protect and secure the internal structure of the modulator, ensuring its stable and reliable operation.

[0003] Silicon photonic modulators, as core components of optical communication systems, are highly susceptible to environmental interference, especially vibration, due to their delicate optical elements and electronic circuits. When silicon photonic modulators are in industrial environments, on vehicles, or in earthquake-prone areas, continuous or sudden vibrations can cause displacement of internal optical elements, poor contact or short circuits in electronic circuits, leading to performance degradation such as reduced extinction ratio and slower modulation rate. Simultaneously, the interfaces at both ends of the modulator, as critical nodes for optical signal transmission, are susceptible to damage if improperly pulled during installation, maintenance, or unexpected situations. This can result in loose interfaces, fiber optic cable breakage, or even circuit board damage, severely hindering stable optical signal transmission. Utility Model Content

[0005] (II) Technical Solution: To achieve the above-mentioned purpose of reducing vibration during the use of the modulator housing, this utility model provides the following technical solution: a vibration-resistant silicon photonic modulator, including a modulator housing, interfaces at both ends of the modulator housing, a fixing hole at the bottom of the modulator housing, the modulator housing being U-shaped, and a base plate slidably connected to the bottom of the modulator housing, elastic airbags on both sides of the modulator housing, the elastic airbags connecting the modulator housing to the base plate, and a side plate fixedly connected to the outside of the elastic airbags, and through holes on each elastic airbag, the through holes communicating with the interfaces.

[0006] Preferably, both ends of the modulator housing and the base plate are provided with slots, and the upper and lower surfaces of the inner side of the elastic airbag are provided with clips, which are fixedly connected in the slots.

[0007] Preferably, a fixing tube is fixedly connected inside the through hole, and the length of the connecting line with the interface inside the fixing tube is greater than the length of the fixing tube.

[0008] Preferably, the upper surfaces of both sides of the modulator housing are provided with scale grooves, and the side plates are provided with calipers that protrude corresponding to the scale grooves.

[0009] Preferably, the front end of the elastic airbag is provided with a fixing plate, the upper surface of the fixing plate is attached to the modulator housing, and the lower surface of the fixing plate is attached to the base plate.

[0010] Preferably, the modulator housing is provided with a plurality of sliding grooves, and the base plate is provided with a plurality of sliders with protrusions matching the sliding grooves, the sliders being slidably installed in the sliding grooves.

[0011] (III) Beneficial Effects: Compared with the prior art, this utility model provides a shock-resistant silicon optical modulator with the following beneficial effects:

[0012] 1. This anti-vibration silicon photonic modulator, through the combined use of a base plate structure, a side plate structure, and an elastic airbag structure, allows the elastic airbag to absorb most of the vibration energy when the modulator is vibrated by environmental factors, due to its unique elasticity and material properties. This effectively reduces the vibration transmitted to the modulator housing. Furthermore, when the connecting lines at both ends of the modulator housing vibrate, the elastic airbag can absorb and disperse the tension transmitted from the connecting lines to the side plate, thus effectively preventing the vibration tension from being directly transmitted to the modulator housing. It also prevents the connecting lines and the lines inside the interfaces from being damaged by tension.

[0013] 2. This anti-vibration silicon photonic modulator, through the combined use of an elastic airbag structure and a caliper structure, allows the amplitude and frequency of vibration to be calculated by observing the sliding distance of the caliper or the change in its relative position with the scale groove when vibration occurs. When no vibration occurs, the temperature change inside the modulator housing can be determined by observing the relative position of the scale groove and the caliper. This monitoring method is intuitive, accurate, and real-time, providing strong support for the temperature control and protection of the modulator. Attached Figure Description

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] Please see Figures 1-7 A shock-resistant silicon photonic modulator includes a modulator housing 1, with interfaces 2 at both ends and fixing holes 3 at the bottom. The modulator housing 1 has a U-shaped design, which optimizes the use of internal space and facilitates the installation of other components. A base plate 4 is slidably connected to the bottom of the modulator housing 1, providing a degree of freedom and allowing the base plate 4 to shift slightly during vibration, thus buffering the impact of vibration on the modulator and improving its shock resistance. Elastic airbags 5 are provided on both sides of the modulator housing 1. The elastic airbags 5 effectively absorb vibrations from all directions, providing multi-directional shock absorption and protecting internal components. The elastic airbags 5 connect the modulator housing 1 to the base plate 4, and side plates 6 are fixedly connected to the outer side of the elastic airbags 5. The side plates 6 not only provide additional support but also fix the elastic airbags 5. Each elastic airbag 5 has through holes that communicate with the interfaces 2.

[0025] Please see Figures 1-8Both ends of the modulator housing 1 and the base plate 4 are provided with slots 7, and the upper and lower surfaces of the inner side of the elastic airbag 5 are provided with retaining strips 8, which are fixedly connected in the slots 7. The retaining strips 8 ensure the stable installation of the elastic airbag 5 and prevent it from falling off during vibration, thereby ensuring the effectiveness of the shock absorption effect. A fixing tube 9 is fixedly connected in the through hole, and the length of the connecting line with the interface 2 inside the fixing tube 9 is greater than the length of the fixing tube 9. This provides a certain amount of room for the connecting line to move, avoids stretching and damage caused by vibration, and improves the reliability of the system. The upper surfaces of both sides of the modulator housing 1 are also provided with scale grooves 10, and the side plate 6 is provided with calipers 11 that are corresponding to the scale grooves 10. The front end of the elastic airbag 5 is provided with a fixing plate 12, the upper surface of the fixing plate 12 is attached to the modulator housing 1, and the lower surface of the fixing plate 12 is attached to the base plate 4. Several sets of sliding grooves are provided inside the modulator housing 1, and several sets of sliders with protrusions matching the sliding grooves are provided on the base plate 4. The sliders are slidably installed in the sliding grooves. The design of the fixing plate 12 ensures the fixed position of the airbag and enhances the stability of the overall structure.

[0026] Working Principle: When using this invention, first, it is fixed in the desired installation position through the fixing holes 3, ensuring that the bottom plate 4 is in contact with a stable platform. Then, the wiring is connected to the interfaces 2 at both ends. When the modulator housing 1 vibrates due to environmental influences, the vibration is first transmitted to the bottom plate 4. Since the bottom plate 4 and the modulator housing 1 are connected by elastic airbags 5, when the vibration is transmitted to the elastic airbags 5, the elastic airbags 5 absorb most of the vibration energy due to their unique elasticity and material properties, thus effectively reducing the vibration transmitted to the modulator housing 1. Furthermore, when the connecting lines connected to the interfaces 2 at both ends of the modulator housing 1 vibrate and swing, the connecting lines will pull the side plates 6. The tension on the side plates 6 will then pull the elastic airbags 5 to extend. In this process, the extension of the elastic airbags 5 acts as a buffer and absorbs energy. It can absorb and disperse the tension transmitted from the connecting lines to the side plates 6, thus effectively preventing the vibration tension from being directly transmitted to the modulator housing 1, and also preventing damage to the connecting lines and the wiring inside the interfaces 2 due to tension.

[0027] When vibration occurs, the magnitude of the vibration can be determined by observing the relative position of the scale groove 10 and the caliper 11. Since the caliper 11 is mounted on the side plate 6, when the elastic airbag 5 extends or contracts, a relative slippage will be observed between the caliper 11 and the scale groove 10. By measuring the distance the caliper 11 slides or observing the change in its relative position with the scale groove 10, the amplitude and frequency of the vibration can be calculated. When no vibration occurs, the temperature change inside the modulator housing 1 can also be determined by observing the relative position of the scale groove 10 and the caliper 11. When the temperature inside the modulator housing 1 changes, the volume of the elastic airbag 5 will also change due to the temperature, thereby causing the caliper 11 to move, reflecting the temperature change. This monitoring method is intuitive, accurate, and real-time, providing strong support for the temperature control and protection of the modulator.
