“…However, even for the all-microring-based case, the obtained BER is below the forward error correction (FEC) limit, which validates the application of microring-based endto-end BPSK link for practical usage. Given the low cost advantage of the silicon platform, the microring-based BPSK link may find application in FTTH networks which has large volume of production and the key factor for deployment is cost [17].…”

We design and demonstrate for the first time an endto-end binary phase-shift keying (BPSK) link based on silicon microring resonators, with an operational bit-rate at 10 Gb/s. The obtained bit-error-rate is below the forward error correction limit, validating the practical application of the demonstrated technique. Performance comparisons to conventional BPSK modulation and demodulation techniques are also made. The microring-based BPSK link promises a compact, energy efficient, and low-cost interconnect solution for high-capacity transceivers.

“…In particular, in the wide fiber-to-the-X applications, demultiplexers operating at two frequencies, namely wavelength diplexers, have received special attention. At present, several schemes have been proposed for multiplexing signals at two different wavelengths, such as diffraction grating couplers coupling two wavelengths to different directions [28,29], on-chip microring resonators for filtering different wavelengths [30], and duplexers based on multimode interference [31,32]. For optical devices, compactness and high integration are among the key points to be considered.…”

Terahertz (THz) spoof surface plasmon polariton (SPP) waveguides can provide subwavelength confinement, which makes it possible for the THz waves to transmit at low loss over long distances along a metallic surface. In this work, an ultra-compact wavelength diplexer formed by THz spoof SPP waveguiding structures is reported on the design and actualization. By adding a certain number of periodic pillars in the coupling part of the directional coupler, the refractive index of the anti-symmetrically distributed odd modes can be engineered, thereby adjusting the coupling length. By adjusting the periodic pillar parameters properly, the SPP modes at two target frequencies will be coupled in the device for an odd or even number of times, so that SPP modes at these two frequencies can be coupled out from different ports. The length of the wavelength diplexer is 1.6 mm, which is about 12.8% of its traditional counterpart. Minimum simulated transmittances of-24.34 dB and-26.27 dB can be obtained at 0.637 THz and 0.667 THz, respectively. The insertion losses at the two operating frequencies are less than 0.46 dB, and the extinction ratios are both better than 19 dB. By cascading the proposed diplexers, a compact wavelength demultiplexer with more channels can be obtained, which has important applications for future THz integrated communication systems.

“…The 10G xPON standard and industry chain will be matured, and 10G xPON will become a mainstream technology for FTTx networks in the coming five years. Technology options for NG-PON2 [6] include wavelength-division multiplexing (WDM)-PON [7,8], optical orthogonal frequency-division multiplexing (OFDM)-PON [9], time and wavelength division multiplexing (TWDM)-PON [10], and high-speed time division multiplexing accesspassive optical network (TDMA-PON).…”

Performance evaluation of an IMDD optical OFDM-CDMA system

In this paper, we propose a modulation technique for passive optical networks that harnesses two-dimensional prime hop system optical code division multiplexing access (OCDMA) and optical orthogonal frequency-division multiplexing (OFDM) for intensity modulation with direct-detection (IMDD) to enhance users' signal capacity in a cost-effective manner. The theoretical analysis is built from an analytical formula that takes into account both multiple-access interference and photodetector noise. Results show that OFDM-OCDMA with multiple users has similar performance to single-user conventional OOFDM for low transmitted powers.
