And Performance

Here, we report on the design and performance of a silicon photonic micro-transceiver required to operate in 5G and 6G environments at high ambient temperatures above 105 °C. The four-channel “IOCore” micro-transceiver incorporates a 1310 nm quantum dot laser system and operates at a data rate of 25 Gbps and higher. The 5 × 5 mm micro-transceiver chip benefits from a multimode coupling interface for low-cost assembly and robust connectivity at high temperatures as well as an optical redundancy scheme, which increases reliability by over an order of magnitude.

The Relationship

Aiming at the difficulty of measuring orientation degree of polymer material online, a soft-sensing approach based on ultrasonic velocity measurement is proposed．Firstly, the ultrasonic velocities of polymer samples are measured using a DSP-based ultrasonic velocity measurement circuit, with the ultrasonic sensor perpendicular to the extrusion direction of polymer material, the orientation degrees of samples are calibrated with infrared spectroscopy, the relationship between the ultrasonic velocities and the orientation degrees are then established based on SVM. With the measurement model and the ultrasonic velocity measured online, the orientation degree of polymer material can then be measured online. Test results in Lab shows that this approach can implement accurate measurement, and the relative error is about 5%.
