“…Due to the recent standardization activities of 100 Gigabit Ethernet (100 GbE), there have been growing interests in the 100-Gb/s PON [9]. For example, it has been already demonstrated that 100-Gb/s PON can be realized by using the optical orthogonal-frequency-division-multiple access (OFDMA) technique [10][11][12].…”

This article presents long reach wavelength division multiplexing passive optical network (WDM‐PON) system capable of delivering 100 Gb/s data to each subscriber. For cost‐effectiveness, WDM‐PON is implemented in loopback configuration using directly modulated reflective semiconductor optical amplifiers (RSOAs) at 25 Gb/s. We use four RSOAs at each optical network unit for the 100‐Gb/s upstream transmission. The operating wavelengths of these RSOAs are separated by the free‐spectral range of the cyclic arrayed waveguide gratings used at the central office and remote node (RN) for (de)multiplexing the WDM channels. We extend the maximum reach of this WDM‐PON to 123 km by using Erbium‐doped fiber amplifiers at the RN. The results show that the error‐free transmission can be achieved for all WDM channels in the wavelength range of >35 nm with sufficient power margins. Bit error rate and Q‐factor were measured to demonstrate the proposed scheme. In this article, long reach and large data service aspects of an access network are presented. © 2013 Wiley Periodicals, Inc.

“…The smaller the device, the less power required. Moreover, integrated photonic functions with redundancy enable flexible and energy-efficient network operation [2]. Si photonics, one of the most promising technologies for such high-density photonic integration, enables monolithic integration of photonic devices made of Si and Ge on a Si wafer.…”

By way of a brief review of Si photonics technology, we show that significant improvements in device performance are necessary for practical telecommunications applications. In order to improve device performance in Si photonics, we have developed a Si-Ge-silica monolithic integration platform, on which compact Si-Ge–based modulators/detectors and silica-based high-performance wavelength filters are monolithically integrated. The platform features low-temperature silica film deposition, which cannot damage Si-Ge–based active devices. Using this platform, we have developed various integrated photonic devices for broadband telecommunications applications.

For practical data communications applications highly-integrated silicon-based photonic devices, we have developed a silicongermanium-silica monolithic photonic integration platform, on which high-performance silica-based passive devices and compact, high-speed silicon-based dynamic/active devices can be monolithically integrated. In the Si-Ge-silica monolithic integration, it is important to deposit index-controllable silica at a low temperature, so as not to damage the Si-and Ge-based active/dynamic devices. Using this platform, various kind of photonic devices have been integrated on a small silicon ship. On this photonic platform, moreover, high-speed electronic circuits can also be integrated.
