The evolution of next-generation cellular networks is aimed at creating faster, more reliable solutions. Both the next-generation 6G network and the metaverse require high transmission speeds. Visible light communication (VLC) is deemed an important ancillary technology to wireless communication. It has shown potential for a wide range of applications in next-generation communication. Micro light-emitting diodes (μLEDs) are ideal light sources for high-speed VLC, owing to their high modulation bandwidths. In this review, an overview of μLEDs for VLC is presented. Methods to improve the modulation bandwidth are discussed in terms of epitaxy optimization, crystal orientation, and active region structure. Moreover, electroluminescent white LEDs, photoluminescent white LEDs based on phosphor or quantum-dot color conversion, and μLED-based detectors for VLC are introduced. Finally, the latest high-speed VLC applications and the application prospects of VLC in 6G are introduced, including underwater VLC and artificial intelligence-based VLC systems.

Abstrak -Penerapan visible light communication (VLC) berlandaskan pada pedoman IEEE 802.15.17 yang mana aturan tersebut baru dirancang dalam waktu 5 tahun belakangan ini (sejak tahun 2009), didalamnya meliputi standar layer fisik (physical layer) dan layer MAC (medium access control). Sebagaimana teknologi komunikasi pada umumnya, VLC juga menyediakan akses security yang dibahas pada bagian layer MAC. Namun pada praktiknya masih belum begitu masif dilakukan oleh para peneliti. Hal ini sangat wajar karena mengingat VLC merupakan teknologi yang sedang dalam tahap pengembangan, yang menjadikan penelitian VLC umumnya berfokus pada 'bagaimana meningkatkan speed dari keterbatasan komponen-komponen pembangun (IC, photodiode, LED, transistor) yang tersedia saat ini. Tantangan teknologi VLC selain target peningkatan kecepatan bit-rate, mobility communication, mengurangi interference noise, menyediakan layanan multi-acces juga salah satunya adalah isu security. Makalah ini merupakan studi literature (review paper) yang didapatkan dari dokumendokumen hasil peneltian baik di jurnal dan conference terkait dengan praktik-praktik security VLC yang pernah dilakukan dengan skema indoor maupun outdoor. Kata kunci -VLC, Security, Komunikasi dan Informasi, ReviewAbstract -Implementing VLC system is based on IEEE 802.15.17 standard where this guideline was designed within the past 5 years ago (since 2009), this guideline covers standard of physical layer (PHY) and medium access control layer (MAC). As communication technology in general, VLC provide security acces which discuss in MAC layer part. However in real practice, we found that they haven't been massively conducted by researchers in the world. The reality is very reasonable due to this technology is under development, it can make VLC studies commonly are focus on "how to increase the speed of VLC with limitations components which are available at this time (such as ICs, photodiodes, LEDs, transistors, etc.)". VLC technology challenges, not only 1) to increase the speed of bit-rate, 2) serve mobility communication, 3) reduce noise interference, 4) providing multi-service acces, but also how to implement security issues in VLC. This paper is a study of literature (review paper) which are obtained from the scientific documents from journals and conferences related to security practices VLC both for indoor and outdoor schemes. Haas di tahun 2011 tentang Light Fidelity (Li-Fi) pada forum TEDx menujukkan bahwa terobosan teknologi ini dapat dijadikan alternatif komunikasi masa depan yang mana memiliki kelebihan dibandingkan teknologi komunikasi wireless lain seperti infra-red, fiber-optic dan radio frequency, yakni bebas regulasi, cakupan bandwidth yang lebih besar, aman untuk kesehatan dan masih banyak yang lainnya. Sifat dari visible light adalah tidak dapat menembus objek padat seperti
