On November 6, the 3rd China International Import Expo is being held in full swing. Chinese technology company SHJC Optoelectronics Technology Group brings the latest high-tech modulation chips, LCOS optical engines, LCOS optical platforms, LCOS microdisplay chip projectors, AR/VR glasses and other products.
Also at the same exhibition is the WSS wavelength selective switch based on LCOS chip research and development, which adopts free-space wavelength switching, supports data uplink/downlink transmission, and can realize signal crossover in optical fiber communication. It is the core technology for new infrastructure networks to achieve 5G speed. support.
"5G will push telecom operators to further increase their network transmission rates, and WSS based on LCOS chip technology will become the core component of 5G networks.
SHJC is currently the only company in China that has mastered the four core technologies and capabilities of LCOS chip design, liquid crystal inorganic orientation, packaging and testing, and optical design.
In November last year, the first domestic (inorganic-oriented) LCOS chip developed by itself was "lit up" in Shanghai, breaking the technological monopoly of the United States and Japan in this field.
LCOS light modulation chip
The LCOS chip is a light control chip that organically combines liquid crystal technology and cmos technology for light phase modulation, which can form a phase grating, and then realize the dispersion, separation and selection of mixed white light.
LCOS optical engine
LCOS is the core light modulation component in industries such as near-eye display, micro-projection, beam modulation, three-dimensional scanning, and 3D printing. It is also the only LCOS chip with mass-produced analog circuits in China.
