At present, the smart devices on the market require smaller and smaller volumes, and optical modules are developing towards highly integrated small packages. It has become increasingly difficult for traditional optical modules with separate laser emitters and photodetectors to meet market demands.
The VCSEL components with integrated transceivers are packaged in a plane, and the size is only 3.5x2.8mm, which is easy to integrate. Greatly shorten the product development and production cycle, reduce the purchase of vital parts, and reduce production costs, so it is very popular with customers.
The VCSEL component with integrated transmission and reception includes both the transmitting part and the receiving part. The transmitting part is a VCSEL chip, and the receiving part is a photodetector or photodiode chip.
940nm 6mW with PD VCSEL diode is a multi-mode VCSEL diode, the receiving part uses a high-sensitivity photodiode with a band-pass filter, which greatly reduces the ambient light stray light interference, the signal-to-noise ratio can be greatly improved, making The product has excellent sending and receiving characteristics. Its wavelength drift is low, only 0.07nm/℃, high reliability; advanced oxidation isolation technology, low threshold current; easy to collimate, comparable to the industry level.
It can be widely used in safety light curtain, particle sensor, laser ranging, axial optical cable, temperature measurement, laser medical treatment and other fields.
