[0040] In order to make the purpose, technical scheme and advantages of the utility model more clearly, the following will be further described in detail by combining with the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the utility model, and are not used to limit the utility model.
[0041] Embodiment 1:
[0042] As Figures 1-4 shown, the utility model provides a prism + wavelength division multiplexer assembly (coupling light into photodetector) can better meet the development needs of future optical communication system, can meet higher transmission rate, and more complex modulation format, at the same time, the loss is very small, and the channel quality is very good.
[0043] The utility model provides a kind of optical assembly for optical module, including optical connector component 1, optical fiber 2, collimating focusing lens 5, wavelength division multiplexing component 6, second optical component and photoelectric detector 8, photoelectric detector 8 is receiving end, second optical component selects turning prism 9 and lens 10, wavelength division multiplexing component 6 selects wavelength division multiplexer.These components are designed by specific space layout and optical path, realize efficient optical signal transmission and processing function.
[0044] In optical path layout aspect, optical connector component 1, optical fiber 2 and collimating focusing lens 5 are coaxially arranged in sequence according to optical signal transmission direction.Optical fiber 2 is provided with tail fiber 3 at end, and tail fiber 3 is designed in square, and is located between collimating focusing lens 5 and optical connector component 1.Collimating focusing lens 5 is designed in square cylindrical surface lens, which helps to improve installation stability and space utilization.
[0045] Wavelength division multiplexing component 6 is provided with first filter 6-1, second filter 6-2, third filter 6-3 and fourth filter 6-4, which are arranged one by one with collimating sheet component 7, for realizing accurate wave division of optical signal.
[0046] Turning prism 9 and lens 10 are an innovative design point of the utility model, which includes two functional components: turning prism 9 for realizing signal light angle rotation and lens 10 connected thereto.Turning prism 9 has an inclined surface with 135° angle with optical path, and through the design of this specific angle, the accurate turning of optical signal can be realized.Lens 10 is responsible for converging coupling of the turned optical signal, and is arranged one by one with photoelectric detector 8, to ensure that optical signal can be efficiently transmitted to detector.Optical signal enters turning prism 9, and is turned by turning prism 9, and then converges through lens 10, and finally is transmitted to photoelectric detector 8 for detection and processing;Or optical signal can first pass through lens 10, and then pass through 9 turning prism to receiving end.
[0047] Further, the entire optical assembly of the utility model uses substrate 4 as carrier platform, and all optical elements are fixed on the substrate.In particular, tail fiber 3, collimating focusing lens 5, wavelength division multiplexing component 6 and turning prism 9 are fixed on the upper end face of substrate 4 by cementing method, and photoelectric detector 8 is cemented on the side end face of substrate 4.This layout design not only optimizes space utilization, but also facilitates the installation and maintenance of device, and photoelectric detector 8 can also be not connected with substrate 4, but arranged on other devices.
[0048] In actual operation, after the optical receiver RX port receives the signal source, the optical signal is first transmitted sequentially through the optical connector assembly 1 and optical fiber 2 to the pigtail 3. The light emitted from the pigtail 3 is focused and collimated by the collimating lens 5 before being transmitted to the wavelength division multiplexing (WDM) component 6. Within the WDM component 6, the optical signal is split into signals of different wavelengths by the filtering effects of the first filter 6-1, the second filter 6-2, the third filter 6-3, and the fourth filter 6-4.

These wavelength-splitting signals are transmitted to the corresponding light-adjusting plate assembly 7. After the angle is finely adjusted by the light-adjusting plate 7-1, the optical signal enters the steering prism 9, which redirects the optical signal. Then, it is converged by the lens 10 and finally transmitted to the photodetector 8 for detection and processing.

This scheme optimizes the optical path structure, reduces the number of optical signal couplings, and further improves the system's transmission efficiency. The specific implementation of this embodiment is described below:
[0053] The optical components provided in this embodiment can be applied to the following optical module, which adopts a two-layer layout design. The upper layer includes an optical connector assembly 1, an optical fiber 2, and a wavelength division multiplexing component 6, while the lower layer is equipped with a photodetector 8. A pigtail 3 is provided at the end of the optical fiber 2, located between the pigtail 3 and the optical connector assembly 1, for achieving stable transmission of optical signals.
[0054] One important innovation of the embodiment is that a first optical component is arranged between the WDM component 6 and the collimating focusing lens 5, which is an angle prism lens. The main function of the collimating focusing lens 5 is to focus the light beam from the output and accurately input it into the input end of the WDM component 6. By directly bonding the angle prism lens with the WDM component 6, the coupling loss of the optical signal is significantly reduced.
[0055] Between the WDM component 6 and the photodetector 8, the embodiment designs a second optical component for realizing the steering transmission of the light beam. The component includes two key components: a lens 10 and a steering prism 9. The lens 10 first performs converging coupling processing on the light beam, and then the steering prism 9 steers the converged light beam to the photodetector 8. The design sequence of "focusing first and then steering" is another innovation of the embodiment.
[0056] In order to realize the accurate adjustment of the optical signal, a light adjusting sheet assembly 7 is arranged between the WDM component 6 and the second optical component. Each light adjusting sheet assembly 7 includes two parts: a light adjusting sheet base 7-2 and a light adjusting sheet 7-1 mounted thereon. These light adjusting sheet assemblies are arranged one by one corresponding to the filter sheets on the WDM component 6, and the angle of the signal light can be accurately fine-tuned through the light adjusting sheet 7-1.
[0057] In actual work process, when the signal light is received by the optical receiver RX port, the optical signal is first transmitted to the pigtail 3 through the optical connector assembly 1 and the optical fiber 2 in sequence. The light emitted from the pigtail 3 is focused and collimated by the angle prism lens and transmitted to the WDM component 6. After the wavelength division processing of the WDM component 6, the optical signal is transmitted to the corresponding light adjusting sheet assembly 7 for angle fine-tuning. Then, the lens 10 adjusts the focal length of the signal light, and finally the optical signal is transmitted to the photodetector 8 through the steering prism 9 for detection and processing. All devices are fixed on the substrate 4 through reliable bonding process, ensuring the stability of the system.
[0058] Compared with the embodiment 1, the embodiment has the following two main technical innovations: first, the collimating lens is replaced by an angle prism lens matched with the WDM component 6, and the direct bonding method is used to connect with the WDM component 6, effectively reducing the optical signal coupling process; second, in the processing sequence of the optical signal, the design scheme of "focusing first and then steering" is adopted, which further optimizes the optical transmission efficiency. These innovative designs make the embodiment further reduce the transmission loss of the system while maintaining high channel quality.
[0059] Embodiment 3:
[0060] As Figures 7-8As shown, the utility model provides another optical assembly design scheme. This scheme reduces the coupling times of optical signals by optimizing the optical path structure, and further improves the transmission efficiency of the system. The specific implementation of the embodiment is described below:
[0061] The optical assembly provided by the embodiment can be applied to the following optical module, which adopts a two-layer layout design, wherein the upper layer comprises an optical connector assembly 1, an optical fiber 2, and a wavelength division multiplexing component 6, and the lower layer is provided with a photodetector 8. An optical fiber 3 is arranged at the end of the optical fiber 2, for realizing stable transmission of optical signals.
[0062] The optical assembly is composed of an inclined prism lens directly connected with the wavelength division multiplexing component 6, which mainly functions to focus the output light beam and accurately input it into the input end of the wavelength division multiplexing component 6. By directly bonding the inclined prism lens with the wavelength division multiplexing component 6, the coupling loss of optical signals is significantly reduced.
[0063] Between the wavelength division multiplexing component 6 and the photodetector 8, the embodiment designs a second optical component for realizing the steering transmission of the light beam. The component comprises two key components: an integrated lens 10 and a steering prism 9. Among them, the lens 10 first performs converging coupling processing on the light beam, and then the steering prism 9 transmits the converged light beam to the photodetector 8. The design sequence of "focusing first and then steering" is another innovation point of the embodiment.
[0064] Further, the steering prism 9 is composed of four pieces of shape-same sub-prisms, the number of which corresponds to the number of light beams output by the wavelength division multiplexing component 6. The four pieces of shape-same sub-prisms respectively perform optical path steering, collimation and convergence on four signal lights, thereby improving the coupling efficiency.
[0065] In order to realize accurate adjustment of optical signals, a light adjusting sheet assembly 7 is arranged between the wavelength division multiplexing component 6 and the second optical component. Each light adjusting sheet assembly 7 comprises two parts: a light adjusting sheet base 7-2 and a light adjusting sheet 7-1 mounted thereon. These light adjusting sheet assemblies are arranged one by one corresponding to the filter sheets on the wavelength division multiplexing component 6, and the angle of the signal light can be accurately fine-tuned through the light adjusting sheet 7-1.
[0066] In actual operation, after the optical receiver's RX port receives the signal light, the optical signal is first transmitted sequentially through the optical connector assembly 1 and optical fiber 2 to the pigtail 3. The light emitted from the pigtail 3 is focused and collimated by an angled prism lens and transmitted to the wavelength division multiplexing (WDM) component 6. After wavelength division multiplexing by the WDM component 6, the optical signal is transmitted to the corresponding optical adjustment plate assembly 7 for angle fine-tuning. Subsequently, the lens 10 adjusts the focus of the signal light, and finally, the optical signal is transmitted to the photodetector 8 for detection and processing via the steering prism 9. All components are reliably bonded to the substrate 4, ensuring the stability of the system.
[0067] This embodiment has the following two main technical innovations: Compared with the long, integral prism structure used in embodiments 1 and 2, this invention adopts a split structure, in which each channel is separate and independent. These innovative designs enable this embodiment to further reduce the transmission loss of the system while maintaining high channel quality.
[0068] Example 4:
[0069] like Figures 9-10 As shown, this utility model provides a third optical component design scheme. This scheme innovatively employs a steering collimating lens design, achieving the integration of optical signal collimation and steering functions. The specific implementation of this embodiment is described below:
[0070] The optical components provided in this embodiment can be applied to the following optical module, which also adopts a two-layer layout structure. The upper layer contains an optical connector assembly 1, an optical fiber 2, and a wavelength division multiplexing component 6, while the lower layer contains a photodetector 8. The end of the optical fiber 2 is provided with a pigtail 3 to ensure stable transmission of optical signals.
[0071] This embodiment includes a first optical component, comprising an angled prism lens directly connected to the wavelength division multiplexing (WDM) component 6. The main function of this angled prism lens is to focus the light beam and accurately input it to the input terminal of the WDM component 6. The direct connection between the angled prism lens and the WDM component 6 effectively reduces optical signal coupling loss.
[0072] The core innovation of this embodiment lies in the design of the second optical component. This component employs four steering prisms 9, each possessing the dual functions of beam collimation and focusing, and optical path steering. This innovative design integrates the collimation and focusing functions, which previously required separate operations, into a single device, significantly simplifying the optical path structure. The cross-section of the steering prism 9 can be selected in different shapes according to specific application requirements, including circular, semi-circular, fan-shaped, or polygonal shapes. This flexible design provides more options for different application scenarios.
[0073] In actual work process, when the optical receiver RX port receives signal light, the optical signal first passes through the optical connector assembly 1 and the optical fiber 2 in turn to the pigtail 3. The light emitted from the pigtail 3 is focused and collimated by the bevel prism lens, and is transmitted to the wavelength division multiplexing component 6. After the wave division processing is completed in the wavelength division multiplexing component 6, the optical signals of different wavelengths are transmitted to the corresponding turning prism 9 respectively. Each turning prism 9 receives the optical signal and simultaneously completes the functions of collimation and light path turning, and directly transmits the processed optical signal to the photodetector 8 for detection and processing.
[0074] Compared with the first two embodiments, the main technical innovation of the embodiment is the use of a turning prism 9 with higher functional integration. This design not only simplifies the optical path structure and reduces the number of devices, but also improves the integration and reliability of the system. By integrating the collimation and light path turning functions into a single device, the transmission efficiency of the optical signal is further optimized, and the space utilization of the system is also improved.

The end of the optical fiber 2 is provided with a pigtail 3, and the pigtail is located between the wavelength division multiplexing component 6 and the optical connector assembly 1.
[0077] The core innovation of the embodiment lies in the integrated design of the wavelength division multiplexing component 6. The wavelength division multiplexing component 6 is tightly integrated by three functional modules, namely the light-in collimating lens 11-1, the wavelength division multiplexer 11-2 and the exit lens 11-3.

This design simplifies the optical path structure while ensuring good optical signal transmission effect.
[0079] In actual work process, when the optical receiver RX port receives the signal light, the optical signal first passes through the optical connector assembly 1 and the optical fiber 2 in turn, and is transmitted to the pigtail 3. Then, the optical signal enters the wavelength division multiplexing component 6, is focused by the light-in collimating lens 11-1, and is subjected to wave separation processing in the wavelength division multiplexing device 11-2. The wave-separated optical signal is collimated and focused by the light-out lens 11-3, and finally the optical signal is turned and transmitted to the photodetector 8 by the prism 15 for detection and processing. All devices are fixed on the substrate 10 through reliable bonding process, ensuring the stability of the system.
