In this paper, vertical cavity surface emitting laser (VCSEL) array is used to establish gigabits/second (Gbps) optical uplink, device-to-device (D2D), and Internet-of-thing (IoT) links, as a suppl…
When confronted with a new product, consumers often find it difficult to predict how it will perform, and such uncertainty reduces consumers’ willingness to adopt the product. In this paper, we c…
A two-dimensional grating coupler (2D GC) with four access waveguides is proposed and demonstrated for polarization independent and perfectly vertical coupling. Benefitting from the perfectly verti…
We propose and experimentally demonstrate a vertical fibre interfacing interleaved angled MMI (AMMI) for wavelength division (de)multiplexing (WDM) near 1550 nm. This 6-channel WDM device is compo…
Very-long-wave-infrared (VLWIR) photodetectors have attracted great attention from scientists worldwide in the ground and space-based detections, imaging and early warning. However, the application…
