High-Speed and High-Brightness 850 and 1060 nm VCSEL Arrays for Free-space Optical Communication

Jian-Wei Tung, Po-Jui Lai, Zhe-Wei Hsu, Jia-Liang Yen et autres

Vertical-cavity surface-emitting laser (VCSEL) arrays featuring high-speed and exceptional brightness are critical for minimizing diffraction loss on the receiver side of optical wireless communication (OWC) channels, especially in 6G and satellite communications. Compared with their edge emitting counterpart, such as DFB lasers, …

Miniaturized VCSEL Array With Ring-Shaped Zn-Diffusion Apertures for High-Speed and High-Brightness Performances

Jian-Wei Tung, Zhe-Wei Hsu, Po-Jui Lai, Jin Wei Shi

Miniaturized$7 \times 7$VCSEL arrays with ring-shaped Zn-diffusion apertures are demonstrated to suppress spatial-holeburning under high-brightness output. State-of-the-art performances in terms of wide bandwidth (22 GHz), high output power$(160 ~\text{mW})$and high brightness$\left(73 \text{KWcm}^{-2} \text{sr}^{-1}\right)$can be simultaneously achieved for 32 Gbps on-off keying error-free …
