[0024] Figure 1 is a structural schematic diagram of the optical module 10 of the embodiments of the present application. It is to be noted that the optical module 10 provided by the present application is not limited to the structure shown in Figure 1 the drawings. The optical module 10 comprises: a power grid port 11, a micro-control processor 12, an optical engine platform 13, and a printed circuit board 14. The power grid port 11 is used to receive external electrical signal data and output processed output electrical signal data to the outside; the optical engine platform 13 is used to receive the first electrical signal data, perform signal processing and conversion on the first electrical signal data, and obtain converted output optical signal data; receive external optical signal data, perform signal processing and conversion on the external optical signal data, and obtain converted output optical signal data or second electrical signal data, and output the output optical signal data or the second electrical signal data; the micro-control processor 12 is used to control the power grid port 11 and the optical engine platform 13, and regulate the transmission and parameters of electrical signals and optical signals in the optical module 10; the printed circuit board 14 is used to carry the power grid port 11, the optical engine platform 13, and the micro-control processor 12.
[0025] The Ethernet port is a physical interface on network communication devices such as computers, servers, routers, network cards, and optical modules, used to connect to Ethernet. It usually uses an RJ45 interface to connect to a network cable for data transmission and communication. Ethernet is a widely used LAN technology that uses cables or wireless networks to connect computers, servers, routers, and other devices, allowing devices to transmit and share data. In Ethernet, devices are connected to Ethernet through the Ethernet port and communicate through the Ethernet protocol. It should be noted that the Ethernet port not only supports adaptive transmission speed (adapt to the speed of other devices in the network), but also works in full duplex or half duplex mode. In full duplex mode, the Ethernet port can send and receive data simultaneously, while in half duplex mode, the Ethernet port can only send or receive data.
[0026] Figure 2 The structure of the optical engine platform 13 of the embodiment of the present application is shown in FIG. 1. It should be noted that the optical engine platform 13 provided by the present application is not limited to the structure shown in FIG. 1, as long as the results are substantially the same. Figure 2 The optical engine platform 13 includes a first driver 131, a silicon optical engine 132, a second driver 133, a transimpedance amplifier 134, and a sub-substrate 135. The first driver 131 is used to receive external electrical signal data and perform signal amplification processing on the external electrical signal data to obtain first electrical signal data after amplification processing. The silicon optical engine 132 is used to receive the first optical signal data and convert the first optical signal data into output optical signal data. It also receives external optical signal data and converts the external optical signal data into third electrical signal data. The second driver 133 is used to receive the second electrical signal data and perform clock and data recovery processing on the second electrical signal data to obtain the output electrical signal data. The transimpedance amplifier 134 is used to receive the third electrical signal data and perform amplification processing on the third electrical signal data to obtain fourth electrical signal data, output the fourth electrical signal data to the silicon optical engine 132, or set the fourth electrical signal data as the second electrical signal data. The sub-substrate 135 is used to carry the first driver 131, the second driver 133, the transimpedance amplifier 134, and the silicon optical engine 132.
[0027] Further, the silicon optical engine 132 includes a direct modulation laser 1323 and an arrayed waveguide grating 1324. The direct modulation laser 1323 is used to receive the first electrical signal data, convert the first electrical signal data into first optical signal data, and output the first optical signal data. The arrayed waveguide grating 1324 is used to receive the first optical signal data and convert the first optical signal data of a single optical signal into second optical signal data of multiple optical signals.
[0028] Preferably, the second driver 133 can be a clock and data recovery (CDR) device. Since the optical signal can be affected by various noises and disturbances during transmission, the clock and data information can be distorted or drifted. Therefore, a clock and data recovery device is needed to recover and stabilize the signal. The clock and data recovery device can recover the original signal by sampling and comparing the clock and data information in the optical signal, and keep it stable. The algorithm and technology used by the clock and data recovery device can be optimized and adjusted according to different types of optical signals and transmission distances to improve the accuracy and stability of the recovery, ensuring the quality and reliability of the optical signal, and realizing high-speed and long-distance optical communication transmission.
[0029] It should be noted that the optical engine platform 13 uses a 2.5D packaging technology. The 2.5D packaging technology is a chip packaging technology used to manufacture high-performance integrated circuits (ICs) and system packages, and is a technology between traditional 2D packaging and 3D packaging. In the 2.5D packaging technology, multiple chips (such as processors, memories, graphics processors, etc.) are assembled together to form an integrated system chip (SiP). These chips are usually stacked together and connected through a silicon interposer. The silicon interposer is a high-density interposer that can provide high-speed, low-latency data transmission channels between multiple chips. Compared with traditional 2D packaging, 2.5D packaging technology has higher performance and smaller packaging size, which can provide higher bandwidth and lower latency, while also reducing signal transmission interference and power consumption. Compared with 3D packaging, 2.5D packaging technology is easier to implement, more cost-effective, and can use standard manufacturing processes and equipment.
[0030] In addition, the aforementioned optical engine platform 13 also provides high scalability and can be applied to different rate optical modules. Specifically, the silicon optical engine can be replaced according to the optical communication requirements to realize optical modules with transmission rates of 100G, 200G, 400G, 800G, or even higher rates. However, the prior art needs to change the existing optical module design and various optical devices, which requires a lot of manpower, material resources, and time costs.
[0031] The Direct Modulation Laser (DML) 1323 is a semiconductor laser that works by injecting current into a semiconductor material to generate laser light. The intensity and frequency of the output light can be changed by altering the intensity and frequency of the injected current. Since the direct modulation laser does not require an external modulator, it offers advantages such as simplicity, compactness, and cost-effectiveness, and also enables high-speed data transmission.
[0032] The transimpedance amplifier (TIA) 134 converts the weak current generated by the photodiode into a voltage signal that can be used in other circuits. The basic principle is to convert the current generated by the photodiode into a voltage signal that is proportional to it. When light shines on the photodiode, photons excite electrons and generate current. The TIA converts this current into an output voltage signal.
[0033] The Array Waveguide Grating (AWG) 1324 consists of a series of parallel waveguide devices and gratings, which can achieve efficient optical wave guidance and separation. Each waveguide device represents a channel, while the grating is an optical element used to separate and recombine signals. When multiple optical signals of different wavelengths pass through the AWG, the optical signals of different wavelengths will interfere in the grating, thereby separating the optical signal of each wavelength to different output ports.
[0034] Figure 3 This is a schematic diagram of the silicon photonics engine 132 according to an embodiment of this application. It should be noted that, if substantially the same equivalent result exists, the silicon photonics engine 132 provided in this application is not based on... Figure 3 The structure shown is for illustrative purposes only. The silicon photonics engine 132 includes: a light receiving unit 1321 and a light emitting unit 1322. The light receiving unit 1321 is used to receive the external optical signal data, convert the external optical signal data into the third electrical signal data, and output the third electrical signal data to the transimpedance amplifier 134; the light emitting unit 1322 is used to receive the first optical signal data or the fourth electrical signal data, and convert the first optical signal data or the fourth electrical signal data into the output optical signal data.
[0035] Furthermore, such as Figure 3As shown, the light receiving unit 1321 includes an optical splitter 13211 and a light detection chip 13212. The optical splitter 13211 is used to convert the external optical signal data of a single optical signal into third optical signal data of a multi-channel optical signal, and output the third optical signal data through a waveguide 13213; the light detection chip 13212 is used to receive the third optical signal data through a waveguide, and convert the optical signal data into the third electrical signal data.
[0036] Further, as shown, Figure 3 The light emitting unit includes a laser chip 13222 and an optical combiner 13221. The laser chip 13222 is used to convert the received fourth electrical signal data into fourth optical signal data of a multi-channel optical signal, and output the fourth optical signal data through a waveguide; the optical combiner 13221 is used to convert the fourth optical signal data received through a waveguide, or the second optical signal data received through a waveguide, into the output optical signal data of a single optical signal.
[0037] The light detection chip 13212 and the laser chip 13222 are disposed on the sub-substrate by a flip-chip process. The contacts of the light detection chip 13212 and the laser chip 13222 are connected to the electronic traces in the sub-substrate.
[0038] The flip-chip process is a microelectronic chip packaging technology, mainly used for connecting and packaging chips and substrates. This technology usually uses high-precision automated equipment to perform. First, the electrical connection between the flip-chip and the substrate is direct, which can achieve higher density and smaller pitch compared to traditional cable connections, thereby improving the integration and performance of the chip; second, since the electrical connection between the flip-chip and the substrate is direct, the signal transmission path is shorter, thereby reducing signal transmission delay and loss, improving signal transmission speed and accuracy; third, since the electrical connection between the flip-chip and the substrate is direct, the contact area of the connection is larger and the connection is more reliable, not easily affected by mechanical vibration and temperature changes and other factors, thereby improving the reliability and stability of the entire optical transceiver device; fourth, since the electrical connection between the flip-chip and the substrate is direct, no additional cable connection is needed, thereby achieving a smaller chip packaging volume, suitable for various miniaturized devices and systems. In summary, the flip-chip coupling structure of the light receiving chip obtained by applying the flip-chip process has the advantages of high efficiency, high precision, high density, low cost, etc.
[0039] The optical module provided by the embodiment of the application integrates the light detection chip and the laser chip into the silicon light engine through a flip welding process, adopts a 2.5D packaging technology to further package the silicon light engine to obtain an optical engine platform, and then integrates the optical engine platform into the optical module, so that the external electrical signal can be converted into the optical signal with the preset parameters, the external optical signal can be converted into the electrical signal or the optical signal with the preset parameters, the volume of the optical module is reduced, and the power consumption of the optical module is reduced.
