Book Description

The "blue laser" is an exciting new device used in physics. The potential is now being recognized for its development into a commercial lighting system using about a tenth of the power and with a thousand times the operating lifetime of a comparable conventional system. This comprehensive work introduces the subject at a level suitable for graduate students. It covers the basics physics of light emitting diodes (LEDs) and laser diodes (LDs) based on gallium nitride and related nitride semiconductors, and gives an outline of their structural, transport and optical properties, and the relevant device physics. It begins with the fundamentals, and covers both theory and experiment, as well as an examination of actual and potential device applications. Shuji Nakamura and Nichia Chemicals Industries made the initial breakthroughs in the field, and these have revealed that LEDs and LDs are a sophisticated physical phenomenon and a commercial reality.

Book Description

Realization of the semiconductor laser diodes (LDs) operating in the blue wavelength region had been a 'dream' for a long time for the scientists working on widegap materials until just a few years ago. Quite remarkable progress has been made in the last few years the dream has come true. The first ZnSe-based blue/green LD was fabricated about four years ago and its officially reported life-time in CW operation exceeds 100 hours now; it is quickly approaching a practical use level. Further, GaN-based blue LDs have also been realized. In this way, the progress in these research fields is quite rapid. The work includes articles on bulk growth, epitaxy, doping and characterization, blue LDs and LEDs, and future prospects in both ZnSe-based and GaN-based areas.

Book Description

In 1993, the author, Shuji Nakamura developed the first commercially available blue and green light-emitting diodes. Now he has made the most important breakthrough in solid state laser techniques to date - the first blue semiconductor laser based on GaN. Here, Dr. Nakamura discusses the physical concept and basic manufacturing technology of these new blue light-emitting and laser diodes. he shows how this represents a new era in commercial applications for semiconductors, including displays, road and railway signalling, lighting, scanners, optical data storage, and much more. Moreover, Nakamura provides fascinating background information on the extraordinary realisation of an extremely successful concept of research and development. Of interest to researchers as well as engineers.

Book Description

The 1st edition of the book “Light-Emitting Diodes” was published in 2003. The 2nd edition was published in 2006. The 3rd edition was published in 2018. The current edition, the 2023 edition, is the most recent update of the book. The book is a thorough discussion of LEDs, particularly its semiconductor physics, electrical, optical, material science, thermal, mechanical, and chemical foundations. The book presents many fundamental aspects of LED technology and includes an in-depth discussion of white light-emitting diodes (LEDs), phosphor materials used in white LEDs, packaging technology, and the various efficiencies and efficacies encountered in the context of LEDs. The background of light, color science, and human vision is provided as well. The fully colored illustrations of the current edition are beneficial given the prominent role of light and color in the field of LEDs. The current edition is published in electronic PDF format in order to make the book affordable and easily accessible to a wide readership.

Book Description

In this chapter, we review our recent work on blue laser diode-based visible light communication and solid-state lighting. Gallium nitride (GaN) phosphor-converted white light-emitting diodes (Pc-WLEDs) are emerging as an indispensable solid-state lighting (SSL) source for next-generation display system and the lighting industry. Together with the function of lighting, visible light communication (VLC) using Pc-WLEDs has gained increasing attention to fulfill the growing demand for wireless data communication. Practically, the low modulation response and low emitting intensity of light-emitting diodes (LED) are the drawbacks for the development of ultrahigh-speed VLC and high-quality SSL system. Blue GaN laser diode (LD) and remote phosphor-based white light can be used for both high-speed VLC and SSL simultaneously. We demonstrated a color-rendering index (CRI) of 93.8, a correlated color temperature (CCT) of 4435¬†K, and a data rate of 1.6 Gbps under NRZ-OOK modulation by an exciting blue laser diode on narrowband green,àí/red-emitting composite phosphor film. This work opens up exciting possibilities for future high-speed indoor VLC and high-quality SSL.
