“…This result indicated that the RCLED/Cu emission wavelength stability is due to the superior thermal dissipation by a Cu substrate. The result is superior to the finding reported by Akhter et al [24]. The thermal resistance ( ) of both types of RCLEDs at different injection current is shown in Fig.…”

Abstract-High-performance InGaN-based green resonantcavity light-emitting diodes (RCLEDs) with a plating Cu substrate for plastic optical fiber communication applications are reported. Good stability of emission wavelength was obtained at 0.016 nm/mA. The RCLEDs presents low temperature dependence, showing only a 3% drop in light output power as the temperature increasing from 25 to 85 C. The superior performance can be attributed to the decreased dynamic series resistance and the enhanced thermal dissipation of the heat sink substrate.

“…Recent reports have raised the possibility of using GaN based visible-emitting LEDs for data transfer either in free space or plastic optical fibre. [1][2][3] These have included demonstration 2 of error-free data transmission at rates up to 1 Gbit/s. Fast modulation speeds would also be advantageous for the use of these devices in time-resolved fluorescence measurements.…”

“…According to the media-oriented systems transport (MOST) standard they must run at a data rate of 22.5Mb/s [1,2]. However, the optical bandwidth of the red operating window (~650nm) of the current commercially used polymethylmethacrylate (PMMA) POF is narrower, and the propagation loss higher (0.125dB/m vs. 0.09dB/m) than that of the high-performance POF system [3]. This operates under a PMMA loss minimum window, which has a wavelength of around 500nm [3].…”

We demonstrate cascade green Light-Emitting-Diode (LED) arrays, which have superior output-power to single LED without sacrificing modulation-bandwidth. 80Mbit/sec eye-opening with a 0.65mW coupled power to plastic-optical-fiber is achieved under the output of in-car battery (12V). I. IntroductionHigh-speed red light-emitting diodes (LEDs) [1,2] often serve as key transmitter components for communication networks using plastic optical fibers (POFs). According to the media-oriented systems transport (MOST) standard they must run at a data rate of 22.5Mb/s [1,2]. However, the optical bandwidth of the red operating window (~650nm) of the current commercially used polymethylmethacrylate (PMMA) POF is narrower, and the propagation loss higher (0.125dB/m vs. 0.09dB/m) than that of the high-performance POF system [3]. This operates under a PMMA loss minimum window, which has a wavelength of around 500nm [3]. The III-nitride-based green LEDs would thus be a more promising choice for such applications [3,4]. Furthermore, as compared to the GaAs based red RCLEDs or LEDs, the power and speed performance of III-nitride based LEDs is much less sensitive to the ambient temperature, which is a key issue for in-car application [1][2][3]. However, the speed and power performance of high-speed GaN based green LED is usually poorer than those of reported red high-speed RCLED [2][3][4]. In this paper, we demonstrate a cascade GaN three green LEDs array without using the complex and high-cost distributed-Bragg-reflector (DBR) structure in RCLED. Such device can have a three times larger active area with a three times higher differential efficiency than that of a single LED and sustain a similar modulation bandwidth performance [5]. A clear eye-opening at 80Mbit/sec with a 0.65mW coupled power to POF under the constant voltage bias of in-car battery output (12V) have been achieved simultaneously. The additional transformer-circuits or expensive constant bias current source is not necessary by use of such scheme of bias [6].
