“…Moreover, we have shown that LEDs with other visible wavelengths can also be used as converters and receivers with surprisingly good parameters. Gallium nitride (GaN) based blue LED may offer advantages in the temperature stability and lifetime (Wun et al, 2012) as well as in higher direct output voltages. In the next steps we plan to realize sensor links operating at shorter wavelengths than red.…”

“…For these conventional systems operating in the near infrared at typical wavelengths of 830, 940 and 1480 nm (Werthen, 2006), optical fibers made of silica glass are used mostly because of their low attenuation on the order of a few dB km −1 . Such infrared high-end systems can provide an electrical power of a few hundred milliwatt (Peña et al, 1999) up to several watt (Werthen, 2008). However, the attenuation of silica fibers is larger by an order of magnitude in the visible range of light as used in this paper and as shown later in Table 1.…”

Abstract. Many applications in high voltage or explosive environments require sensors which are electrically isolated from other components of a system. These sensors need remote powering as well as wireless or isolated data transmission links. A possible solution can be based on optically powered optical sensor links. These typically employ four different photonic components: for the data communication a fast LED as a transmitter and a photo diode as a receiver, furthermore for sensor powering a high-power light source and a photonic power converter. Additionally, two optical fibers are required for optical remote powering and the optical data link. In this paper we demonstrate an optically powered optical sensor link using only low-cost high-brightness LEDs and a single polymer optical fiber (POF) for all of these tasks. Coupling efficiencies, power transmission and modulation bandwidths are analyzed for LEDs with different colors. Potentials for many mW of electrical remote powering and Mbit s −1 sensor data links are demonstrated over 10 m of POF. This approach can be used for almost any electronic sensor with moderate power requirements.

“…For optical communication, a reported 2.6 GHz modulation bandwidth in commercial high-power LD shows that LDs can be modulated at least 100 times higher than LEDs [22]. High-speed blue LDs can potentially be suitable for plastic optical fibers (POFs) based low-speed and shortdistance communications [23]. In addition to the modulation speed, a narrow emission spectrum of 2~3 nm allows wavelength-division multiplexing (WDM) as well as OFDM in red-green-blue (RGB) lasers for white light communication [24,25].…”

El-Desouki, Munir M.; Speck, James S.; Nakamura, Shuji; Ooi, Boon S.; DenBaars, Steven P. Abstract:We demonstrate data transmission of unfiltered white light generated by direct modulation of a blue gallium nitride (GaN) laser diode (LD) exciting YAG:Ce phosphors. 1.1 GHz of modulation bandwidth was measured without a limitation from the slow 3.8 MHz phosphor response. A high data transmission rate of 2 Gbit/s was achieved without an optical blue filter using a non-return-to-zero on-off keying (NRZ-OOK) modulation scheme. The measured bit error rate (BER) was less than the forward error correction (FEC) limit of 3.50 × 10 -3 . The generated white light exhibits CIE 1931 chromaticity coordinates of (0.3628, 0.4310) with a color rendering index (CRI) of 58 and a correlated color temperature (CCT) of 4740 K when the LD was operated at 300 mA. The demonstrated laserbased lighting system can be used simultaneously for indoor broadband access and illumination applications with good color stability. Kruglov, and O.
