“…14 The insertion loss of 7 × 7 AWG is 2.4 dB according to the literature. 15 By contrast, the insertion losses in this paper are improved to 4 dB for the 1 × 7 coarse AWG multiplexer and 4 dB for the 7 × 7 fine AWG, respectively. This replaceable word is the insertion loss of D. The insertion loss of the optical switch is 0.7 dB according to the existing work.…”

Abstract. We propose a new code family, called extended shifted prime codes, and the universal encoding architecture for spectral amplitude coding optical code division multiple access systems using a two-code keying scheme. The proposed system can eliminate multiuser interference and suppress phase-induced intensity noise. In addition, we design the ESP codes to be an encoding/decoding architecture based on the array waveguide grating architecture and reduce the power loss and the complexity of the optical line terminal. The numerical results demonstrate that the proposed system with ESP codes outperforms the existing onedimensional shifted prime codes system. © The Authors.

“…The arrayed waveguide grating router (AWGR) is an attractive passive wavelength routing device that consumes almost no power, has less noise accumulation and can switch very fast (only through wavelength conversion) [7]. In an AWGR, the routing of an input signal is solely determined by its wavelength and input port address.…”

“…Adopting optical switching can not only achieve over 100 Tbit/s or even Pbit/s throughputs [6], but also dramatically reduce the power consumption [1], eliminate the high cost O/E/O conversions and thus make the switching operation independent of bit-rate and protocol. The arrayed waveguide grating (AWG) * * is a very attractive passive device for constructing high-speed largecapacity WDM optical switches, because it can switch fast, is scalable to large size, consumes little power and has less noise accumulation [7]. An AWG-based optical switch construction was proposed in [8] based on a single stage AWG.…”

SUMMARYArrayed waveguide grating (AWG) is a promising technology for constructing high-speed large-capacity WDM switches, because it can switch fast, is scalable to large size and consumes little power. To take the full advantage of high-speed AWG, the routing control of a massive AWG-based switch should be as simple as possible. In this paper, we focus on the self-routing design of AWG-based switches with O(1) constant routing complexity and propose a novel construction of self-routing AWG switches that can guarantee the attractive nonblocking property for both the wavelength-to-wavelength and wavelength-to-fiber request models. We also fully analyze the proposed design in terms of its blocking property, hardware cost and crosstalk performance and compare it against traditional designs. It is expected that the proposed construction will be useful for the design and all-optical implementation of future ultra high-speed optical packet/burst switches.

Abstract.A comparative study, in aspects of both wavelength dependence and fabrication tolerance, is carried out between silica-based phase shifters designed in two different regime, namely length difference regime and refractive index difference regime. Results show that in the wavelength range of 1500-1600 nm, phase shifter designed in refractive index difference regime has a working wavelength range 2.8~3.1 times wide as that designed in length difference regime; while in the aspect of fabrication tolerance, phase designed in length difference regime is advantageous, with respect to waveguide core dimension error, and waveguide core refractive index error as well.
