2024

From September 6 to 8, the 24th China International Optoelectronic Expo (CIOE China Optoelectronic Expo) was held at the Shenzhen International Convention and Exhibition Center. CIOE Optoelectronic Expo is the largest optoelectronic industry exhibition in Asia, comprehensively showcasing innovative products, cutting-edge technologies, and market trends in the fields of laser technology, optical communication, optical manufacturing, and optoelectronic materials. Changguang Huaxin showcased its full range of products at the three major booths for Laser (4A125), Sensing (6A52), and Communication (12D16). Together with you, witness the "super energy" of this magical beam of laser light.

Laser Pavilion - Light of Energy, Light of the Future

At the Laser Pavilion, we exhibited new high-power semiconductor laser chips (9XXnm, 50W@330μm) and new high-efficiency LiDAR products (low divergence angle multi-junction VCSEL chips) and new high-speed optical communication chips (50G PAM4 VCSEL and 56GBd PAM4 EML) fiber-coupled modules (915/976nm, output power >1000W, fiber core diameter 300μm) arrays and direct semiconductor lasers (1710nm 100W direct semiconductor laser opens a new era of transparent plastic welding) From upstream chips to downstream direct semiconductor lasers, the full range of products comprehensively demonstrates Changguang Huaxin's deep implementation of the company strategy of "one platform, one fulcrum, horizontal expansion, vertical extension," helping to promote innovative and collaborative development of China's laser industry chain. The exhibition site was continuously crowded, with leaders occasionally visiting to provide guidance.

Mr. Cao Jianlin, former Minister of China's Ministry of Science and Technology, visited to provide guidance.

Mr. Wang Zhihou, Director of the Standing Committee of the People's Congress of Changchun City, Jilin Province, and his delegation visited to provide guidance.

As an industry leader, Changguang Huaxin focuses on research and continuous breakthroughs in frontier laser technologies such as semiconductor laser chips and high-efficiency pump technology, fiber-coupled semiconductor laser pump source module technology, and high-power high-reliability semiconductor laser packaging technology, gradually achieving localization and import substitution of semiconductor laser chips, supporting the high-quality and rapid development of China's laser industry.

Sensing Pavilion - Light of Radar and Sensing

At the Intelligent Sensing Pavilion, Changguang Huaxin made a stunning appearance with chip products in four major application areas: automotive LiDAR, industrial vision, smart home, and smart consumer terminals, including multiple series of LiDAR VCSEL, EEL, SL, and TOF. Relying on more than ten years of EEL mass production experience, Changguang Huaxin has mastered independently controllable core technologies in multi-junction VCSEL and tunnel junctions. This year, we launched multiple new automotive LiDAR products. Changguang Huaxin's low divergence angle multi-junction VCSEL chip power covers 30-1000W, wavelength covers 905–940 nm band, with 86% energy divergence angle <18 degrees, and power density >1500W/A.

Communication Pavilion - Light of Communication and Supercomputing

At the Information and Communication Exhibition Hall, Changguang Huaxin displayed a series of optical communication chips including 10G EML, 10G APD, 50G PAM4 VCSEL, and 56GBd PAM4 EML, covering multi-product applications at 10G/100G~800G rates in access network/data center scenarios. The product performance indicators are excellent, promoting entry into the "light-speed" communication era.
