Quantum Computing

Optical communication is a communication method that uses light waves as carriers and optical fibers as transmission media.
Using optical signals to transmit data, it has advantages such as high transmission speed, large capacity, low loss, and strong anti-interference ability, and is the core transmission technology for modern internet, telecommunication networks, and data centers.

Data centers, as the core infrastructure for big data storage and cloud computing operations, handle the interaction, processing, and distribution of vast amounts of information. The "high speed, stability, and reliability" of data transmission are the core requirements of data centers—whether for real-time synchronization of massive data, low-latency responses of cloud services, or coordinated interaction among multiple devices—all of which depend on the robust performance of the underlying transmission links.

5G communication is the fifth-generation mobile communication technology, featuring three core advantages: high data rate, low latency, and massive connectivity. It not only enhances the mobile internet experience but also supports new applications such as industrial internet, internet of things, autonomous driving, and telemedicine. It is a key infrastructure for the digital economy and intelligent society.

AI is an intelligent engine for communication networks to achieve "autonomous driving", replacing traditional model driven with data-driven approaches, enabling networks to have the ability of self perception, self decision-making, and self evolution.

Vehicle mounted optical communication is a physical layer and data link layer communication technology applied between internal electronic systems of vehicles (sometimes also used for short distances between vehicles and the outside world). Its core feature is to use light waves (usually infrared light) as carriers and optical fibers or free space as transmission media to transmit high-speed data signals between the ECU, sensors, and actuators inside the car.

By leveraging VCSEL technology, companies are able to offer full-stack optical sensing solutions for consumer electronics clients, covering a diverse range of end products such as smartphones, smartwatches, televisions, computers, tablets, wearable devices, and AR/VR systems.

Intelligent driving is a technology that enables vehicles to achieve autonomous perception, decision-making and control through sensors, AI algorithms, high-precision maps, V2X and other technologies.
Evolving from assisted driving to fully autonomous driving, it improves driving safety and eases traffic congestion, and is widely used in passenger vehicles, commercial vehicles and intelligent transportation.

Industrial measurement is a technical method for precision inspection, dimension calibration and quality control of industrial products, components and production processes.
With lasers, vision and sensing equipment, it achieves high-precision, non-contact and automated measurement, widely applied in product inspection, mold processing, aerospace and intelligent manufacturing to ensure product accuracy and stable production.

3D perception refers to the capability of acquiring and understanding 3D spatial information through sensors or algorithms, with its core lying in reconstructing the depth, shape and spatial relationships of objects. Its main technical approaches include:
Active Perception: LiDAR calculates distance by emitting laser beams and measuring reflection time; Structured Light analyzes deformation by projecting speckle patterns.
Passive Perception: Stereo Vision computes depth through parallax from dual cameras; Monocular Depth Estimation infers 3D information from 2D images using AI models.
Emerging Technologies: Event Camera adapts to high-speed scenarios based on dynamic pixel response; Neural Radiance Field (NeRF) renders high-fidelity 3D scenes via deep learning.

Lidar, also known as LIDAR (Light Detection and Ranging), is a radar system that uses laser beams to detect characteristic quantities such as the position and speed of targets. Its working principle is to emit laser beams and receive the reflected signals, and calculate the distance and three-dimensional structure of objects based on the time interval and intensity of the signals. The emitted laser beams can accurately range and image target objects, providing the system with accurate environmental information.

Laser obstacle avoidance is a technology that uses lidar or laser sensors to emit and receive reflected laser light, real-time obtain information such as the distance, position and contour of obstacles, and quickly judge and control equipment to automatically avoid obstacles through algorithms.
It has the characteristics of precise distance measurement, fast response, and strong anti-interference, and is widely used in scenarios such as intelligent robots, drones, intelligent driving, and AGV cars.

Controlled nuclear fusion refers to an engineering and technology system in which light atomic nuclei (such as deuterium and tritium) undergo fusion reactions under extreme high-temperature plasma conditions through artificially controlled methods like magnetic confinement (tokamaks, stellarators) or inertial confinement (lasers, Z-pinch), and the released energy and high-flux neutrons are converted into applications serving energy, industry, aerospace and other fields.

Laser cosmetology is a medical cosmetology technology that can solve many skin problems, such as removing pigment spots, removing red blood streaks, and reducing wrinkles. This method uses the thermal energy emitted by the laser to act on the skin surface, which can effectively alleviate problems such as dull skin tone, pigmentation, and rough skin. It can also treat skin problems such as acne, moles, and age spots.
