Abstract
In this letter, Gallium Nitride (GaN) blue micro-Light-Emitting-Diodes (
$\mu $
LEDs) reported on a 200-mm Silicon substrate are utilized for multi-Gb/s data transmission. The manufacturing process is compatible with CMOS integrated circuit design, paving the way for fully integrated transmitters for
$\mu $
LED-based visible light communications (VLC) or chip-to-chip interconnects. Fiber-guided transmission has been realized using direct current optical-orthogonal frequency division multiplexing (DCO-OFDM) modulation, and a data rate of 5.9 Gb/s at a Bit-Error-Rate (BER) of
$3.8\times 10 ^{-3}$
is reported using a single
$50 \times 50~\mu $
m2 blue
$\mu $
LED. This data rate was further improved to reach 15.5 Gb/s in the case where the
$\mu $
LED is only limited by its non-linear distortions instead of the system’s noise, highlighting the high linearity of GaN
$\mu $
LEDs.
期刊介绍:
IEEE Photonics Technology Letters addresses all aspects of the IEEE Photonics Society Constitutional Field of Interest with emphasis on photonic/lightwave components and applications, laser physics and systems and laser/electro-optics technology. Examples of subject areas for the above areas of concentration are integrated optic and optoelectronic devices, high-power laser arrays (e.g. diode, CO2), free electron lasers, solid, state lasers, laser materials'' interactions and femtosecond laser techniques. The letters journal publishes engineering, applied physics and physics oriented papers. Emphasis is on rapid publication of timely manuscripts. A goal is to provide a focal point of quality engineering-oriented papers in the electro-optics field not found in other rapid-publication journals.
